Snipweg 3. 1118AA Schiphol The NETHERLANDS FT-1000 Operating Manual Errata & Addendum External ALC Voltage On page 19, in the description of the EXT ALC Phono Jack (Item 12), the range of the voltage to be provided by a linear amplifier to reduce excitation is shown with the wrong polarity: the correct range is 0 to —4V. CAT System Addendum for Revision 6.0+ EPROM To improve the versatility of external com- puter control of the FT-1000, a facility to read back only the current memory number, or a 16-byte block of VFO or specified memory parameters has been added to EPROM Q5003 on the Control Unit, from revision 6.0. The installed EPROM revision number can be non-destructively checked by holding the 1 and 3 keys at the upper corners of the key- pad while switching on. The revision number appears after the display test and manufac- turer ID display. If your revision is below 6.0, contact your Yaesu dealer for availability and price of the upgrade. Revision 6.0 EPROM firmware adds two optional parameter bytes (#s 1 and 4) to the Update command: Parameter Byte 1 selects the type (and quantity) of data to be returned by the transceiver, and Parameter Byte 4 specifies, when necessary, which memory to read. This table indicates the possible pa- rameter values, and what they do: Parameter | Data Returned | Comment same as P1=0 All 1,636 bytes earlier revs. Current or P1=1 roy Last-Selected Memory 16-Byte structure for P1=2 Current Operation (either a VFO or Mem) | See the Table Two 16-Byte | on page 38 of P1=3 [structures (32 bytes) | the Operating for Main & Sub VFOs Manual P1=4 and |16-Byte structure for P4=1 - 63h |memory number P4 Table Notes: e Software written for previous firmware revi- sions may not be compatible with revision 6 and later (if the Update command is sent with non-zero parameters). Such software can be made compatible simply by zeroing the Update command parameters. o Parameter Byte 4 is significant only when requesting memory data (with Parameter Byte 1 = 4). Otherwise, Parameter Byte 4 is ignored by the transceiver. Note to Programmers: Yaesu models FT-1000, FT-990 and FT-890 all use similar, although not identical, pro- . gramming interface commands. All of these models share the Read Flags command (OFAh), which returns 5 bytes, the last two of which may be used to uniquely identify the transceiver model: “Read Flags” Model Update Bytes 4 and 5 FT-1000 10h 00h FT-990 09h 90h FT-890 08h 41h YAESU E2710101(204w-0K) 1, General Information - General Description General Description The FI-1000 1s a high performance hf transceiver providing dual-channel reception on all frequencies between 100 kHz and 30 MHz, adjustable transmitter power output of up to 200 watts on all hf amateur radio bands in CW, 555, FM, RI TY and Packet (PT and F2) modes, and up to 50 watts carrier in AM mode, A heavy-duty AC power supply, automatic antenna tuner and 1ambic electronic speed keyer/bug simulator are supplied, built in, as standard accessories, along with eight IF filters for the 2nd and 3rd IFs of the main and sub receivers. Inside the FT-1000, modular construction with ex- tensive use of surface mount components on composite epoxy boards allows greater RF circuit isolation and higher reliability than previous manufacturing techni- ques. A squirrel cage blower in the heart of the trans- ceiver replaces the usual rotary fan to cool the interdigital final heatsinks quietly and efficiently. For exceptionally clean receiver and transmitter performance, the FT-1000 incorporates two 10-bit and three 8-bit Direct Digital Synthesizers for its local oscillators (all driven by a single TCXO master oscil- lator), and the operator’s choice of front end RF ampli- fication (using four FETs in a double push-pull, constant-gain stage), direct feed to the double-balanced quad FET ring mixer, or three levels of RF attenuation in 6-dB steps. Two receiver front ends, IF strips and vios allow simultaneous reception and display of two different frequencies, even in different modes and with different IF bandwidths. Receiver audio can be com- pletely or partially mixed, or monitored separately in each ear. With independent bandwidth and mode selec- tion for each receiver, plus an option for separate anten- nas and bandpass filters, a variety of diversity reception modes are available when both vos are tuned to the same frequency. Six microprocessors in the FT-1000 are program- med to provide the simplest possible control interface tor the operator, even for previously complex applica- rons like diversity reception and hf packet. Two dual- speed tuning knobs allow simple independent adjust- ment of the two vfos at all times. Fine tailoring of the IF passband is made possible with pushbutton crystal filter selection, concentric IF width and shift controls, and an IF notch filter. Separate keys are also provided for band selection, and each band key accesses two subband vfo frequency/mode/filter settings per band, so you can keep separate vio settings for two different parts of the band, on all bands. In addition, 99 scanable memories are provided, each of which stores its own mode and IF filter selection, in addition to frequency, clarifier offset and scan status. The built-in automatic antenna tuner includes 39 memories of its own, auto- matically storing antenna matching setnnes for quick automatic recall later, Of course the front panel keypad can also be used to key in operating frequencies direct- ly, Special installable options for the FT-1000 include the BPF-1 Bandpass Filter Module to allow dual recep- tion on separate antennas (and any hf frequencies), the TCXO-1 Temperature Controlled Crystal Oscillator module for precision stability over an expanded tem- perature range, and of course a wide selection of IF filters to complement the eight already installed as standard, External options include the DVS-2 Digital Voice Synthesizer for continuous recording and instant playback of received signals, and pushbutton pre- recorded transmissions; the SP-3 External Loudspeak- er with audio filters and optional LL-5 Phone Paich module; the YH-775T Stereo Headset; and the MD- les Desktop Microphone and MHE-1gg Hand Micro- phone, Before connecting the power cord, you should read the Installation section carefully, heeding the warnings in that section to avoid damage to the set. After instal- lation, please take time to work through the Operation chapter, referring to the Controls & Connectors chapter as necessary for details. These chapters are intended to be read while siting in front of the FT-1000, so you can try out each control and function as they are described. — page ! 1.

The attenuator control on the BPF-1 can be used either to control sub receiver attenuation separately from the main receiver, or be overridden so that the FT-1000 front panel attenuator knob controls both receivers’ attenuators in parallel. TCXO-1 High Stability Master Reference Oscillator For special applications and environments where extra frequency stability is essential, such as for long- term hf packet monitoring under wide temperature variations, the TCXO-1 provides +0.5-ppm stability from —10) to +60°C for the master reference oscillator.

General Information - Accessories & Options MD-1cs Desk-Top Microphone Designed especially to match the electrical and cos- metic features of the FT-1000, the MD-1cg has 600-0 impedance, and includes up/down scanning buttons and a large PTT switch with latch. SP-5 Loudspeaker with Audio Filters and LL-5 Phone Patch Option Selectable audio high- and lowpass filters together with a large loudspeaker complement the superb audio characteristics of the FT-1000 with your choice of 12 different audio filtering combinations. Two input ter- minals are provided for multiple transceivers, with a front panel switch to select between them. A (mon- aural) phone jack is provided on the front panel to take advantage of the audio filters with headphones. With the optional LL-5 Phone Patch Unit installed in the SP-5, the FT-1000 can be patched to the public telephone network. The LL-5 includes a hybnd trans- former circuit to assure proper impedance matches, and front panel gain controls and level meter to set proper audio levels on the telephone line. YH-778T Lightweight Stereo Headphones Dual samarium-cobalt transducers with sensitivity of 103dB/mW (£2dB, @1 kHz, 350) provide the per- fect match for the FT-1000. During dual receive with the: YH-77ST, one receiver can be monitored in each ear, allowing easy separation of the signals from the two receivers (or the audio can be mixed, if desired). DVS-2 Digital Voice System Serving as either a continuous receiver recorder for instant pushbutton playback, or microphone audio re- corder for multiple on air playback, the DVS-2 applies the advantages of random-access solid-state digital memory to serious communications. All data is stored electronically, with no moving parts except your finger and the pushbutton. More information is on page 33.

Check to see that all controls and switches work freely, and inspect the cab- inet for any signs of damage. Make sure the accessory fuses and plugs pictured on page 3 are included. If any damage 1s found document it completely, and contact the shipping company (or dealer, if you purchased it over the counter) right away. Save the packing mat- erials in case you need to return the set for service. If you have purchased optional internal accessories separately, install them as described in Chapter 6 (page 40). Power Connection The FT-1000 в designed for opération from AC voltage only. Before connecting power, check the label on the rear panel which indicates the AC mains voltage for which your transceiver is currently set. If the volt- age on this label does not match your AC mains volt- age, the taps on the primary of the power transformer in the transceiver must be rewired, and the fuse may have to be changed. This requires only a screwdriver and is not difficult (see below), but you should make sure the transformer is wired correctly before connect- ing power, If you have any doubts about the procedure, contact your dealer for assistance. CAUTION Permanent damage will result if improper AC supply voltage is applied to the transceiver. Your warranty does not cover damage caused by application of improper supply voltage, or use of an improper fuse. We also recommend that you open the fuse holder on the rear panel, and make sure that the fuse is correct for your mains voltage: AC Mains Voltage Fuse Capacity 100, 110 or 117 15A 200, 220 or 234 ВА After making certain the AC voltage for which the transceiver 1s set matches your mains voltage, and that the correct fuse is installed in the fuse holder, connect the AC power cord to the 3-pin AC jack on the rear panel. Wait unl all other transceiver interconnections have been made before connecting the other end of the power cord to the wall outlet . Changing the Power Transformer Primary Winding for Different AC Voltages * Make certain that all cables are disconnected from the transceiver. * Remove the three screws from each side of the transceiver, and two from the top edge of the rear panel. Remove the top cover. * On the left side of the power transformer, locate the clear plastic insulating cover with voltage markings. Remove the four screws affixing this plate, and remove it and the plastic sheet underneath. * AC from the power cable is provided by the grey and white wires connected to the lower row of terminals, and for voltages of 117 V and below, two jumpers are also used. Reconnect these wires for the desired voltage according to the diagram at the right. De not, under any circumstances, change the wiring of the upper row af terminals. * Replace the insulating sheets and their four screws, and the top cover and its eight screws, TY a EE - 4 —— ae Г — — === PE ms — а и. — r wu! == = == о т ha | pi == IC = - = зн "== Г = Log | rr 100 EE = | és VE | ACiO0dY ACT 10V AC117V Lod Mo A EN IMPORTANT! If you change the primary transformer taps, make sure to also change the voltage marking on the label on the rear panel to match the new voltage setting. Also, if you change the trans- former taps for operation from 117V or below [0 220V or above, or vice-versa, you must change the fuse in the fuse holder, as indicated in text above. Do not use slow-blow type fuses. page 5 2. Station Installation - General Setup & AC Power Transceiver Location To assure long life of the components, a primary consideration in setting up the FT-1000 is providing for adequate ventilation around the cabinet, The cooling system of the FT-1000 must be free to draw cool air in at the lower rear of the transceiver, and to expel warm air out of the upper rear panel. Do not place the trans- ceiver on top of another heat-generating device such as a linear amplifier, and do not place equipment, books or papers on top of the transceiver. Also, provide a few centimeters of space on either side of the transceiver, if possible. Avoid heating vents and window locations that could expose the transceiver to excessive direc sunlight, especially in hot chmates. Grounding For protection from shock and proper performance, connect the GND terminal on the rear panel to a good earth ground, using a heavy braided cable of the short- est length possible. All other station equipment should be connected to the same grounding cable, as close together as practical. If you use a computer with or near the FT-1000, you may need to experiment with ground wiring to suppress computer noise in the receiver. Adjusting the Front Feet The two front feet of the FT-1000 can be set in either of two positions, By turning the knurled ring around a (retracted) foot clockwise, the middle of the foot will extend about one centimeter . Turn the ring as far as it will go (about 1/4-turn) to lock the extended foot in place. To retract an extended foot, tum the knurled ring counterclockwise 1/4-turn while pressing on the center of the foot. Adjusting the Front Feet Antenna Considerations У Any antennas connected to the FI-1000 should have coaxial feedlines with 50-£2 impedance, and in- clude a well-grounded lightning arrestor, For the anten- na connected to the main ANT jack, the automatic antén- na tuner in the FT-1000 is capable of matching antennas with an SWR of up to 3:1 or more on the amateur bands to the transmitter. Nevertheless, op- imum performance for both reception and transmis- sion will generally result with an antenna designed to provide a 50-07 unbalanced resistive load at the operat- ing frequency. An antenna that is not designed for resonance at the operating frequency may present too high an SWR to allow proper matching with the built-in antenna tuner, in which case the antenna itself should be readjusted, or an outboard antenna tuner used. If the tuner is unable to bring the SWR down to an acceptable level, attempting to transmit will result in an automatic reduction in power output and increased losses in the feedline. Operation under such conditions is not re- commended: it is better to install another antenna de- signed for that band. Also, if your antenna has a balanced feedpoint and you use a balanced feedline, install a balun between the feedline and the ANT jack of the transceiver. The same precautions apply to any additional (re- ceive-only) antennas connected to the RX ANT jack, or to the BPF-1 (if installed), except that neither of these antennas will have the benefit of the built-in antenna tuner. Therefore, unless such receive-only antennas have an impedance near 50 £2 at the operating frequen- cy, you may need to install an external antenna tuner to obtain optimum performance. Interconnection of Accessories The diagrams on the following pages show inter- connections of various external accessories. If you have any questions on these accessories or connecting devices not shown, contact your dealer for advice. Memory Backup The lithium memory BACKUP switch inside the top access panel is turned on at the factory, allowing vio and memory data to be retained while power is off, Backup current is miniscule, so it 15 not necessary to turn the BACKUP switch off unless the transceiver is to be stored for an extended period. After five or more years of operation the transceiver may fail to retain memories, at which time the lithium battery should be replaced. Contact your dealer for replacement of the battery, or for instructions on how to do so yourself. page 6 2.

Station Installation - Internal Settings Eel a EE | Internal Settings Described here are a few internal settings you may wish to make, as vou become familiar with the FT- 1000, to tailor it to your particular station require- ments. Be careful, however, to avoid tampering with other internal controls, so as not to degrade alignment. A few other internal controls are mentioned in the Controls & Connectors chapter. For full alignment details covering all internal controls, refer to the F7- 1000 Technical Manual. Key Beeper Volume This mimmer potentiometer sets the volume (rela- tive to receiver signal volume as set by the AF control) of the beep that sounds when one of the front panel buttons 1s pressed, CAUTION This adjustment must be made with power applied, and with the cover removed. Although the voltages at exposed places in the trans- ceiver are not dangerous to you, sensitive cir- cuitry canbe damaged by contact with metallic tools. Therefore we recommend using a non- metallic adjustment tool, if available. In any case, avoid touching any components not in- volved in the adjustment, and do not allow anything to fall in the set while the cover is removed. « Disconnect the cables from the transceiver, and tum the set upside-down on the table. 4 « Kemove the ten screws shown below, and remove the bottom cover. « Now place the set on its side, reconnect the AC power cable and antenna. * Turn the transceiver on, and adjust the AF control for normal volume on background noise on à common- ly-used band, « Locate Y R3007 from the photo below, and use a small screwdriver to adjust it for the desired beep volume while repeately pressing a front panel key, « Switch the transceiver off, disconnect the power cable, turn the transceiver on its top again, and re- place the bottom cover and ten screws removed above (unless also setting 51001, as described next). RA ANT Switch Selection Setting with BPF-1 Option (RF Unit Switch S1001) As supplied from the factory, the RX ANT switch on the front panel 15 configured to select a separate receive-only antenna connected to the RX ANT jack on the rear panel. If the BPF-1 Bandpass Filter Option is installed, this switch can be reconfigured to select the SUB RX ANT jack on the BPF-1 instead, by resetting switch §1001 on the RF Unit. Note however, that ser- ting this switch to the E BPF position disables the capability of operating split-frequency with a separate receive antenna (see the schematics on page 29). To gain access to the RF Unit, remove the ten screws shown in the photo at the lower left, and remove the bottom cover. S1001 is located near the back left corner, as shown below. 51001 - page 9 3. Controls & Connectors - Front Panel Controls Front Panel Controls This chapter describes each control and connector on the FT-1000. You can just read through quickly now, but some of the descriptions will be more meaningful if you first work through the Getting Started Tutorial at the beginning of the Operating chapter, and then retum to this chapter with the set powered up, as questions arise during operation. Some controls and switches are disabled under certain conditions, (1) POWER This button turns the transceiver on and off. (2) 2-Position Pushbutton Switches RX ANT When this switch is in the undepressed position, the antenna connected to the main ANTsocket is used for receive (it is always used for transmit). When this switch is depressed (LED indicator on), a second an- tenna connected to the RX ANT 18 used by the receiver(s). If the BPF-1 is installed, this switch can be recon- ficured to select the SUB RX ANT jack on the BPF-1, enabling reception on two antennas, by resetting switch $1001 on the RF Unit (see pages 9 and 29). МОХ This button may be used in place of a microphone PTT switch or CW key to manually activate the trans- mitter, when depressed. It must be in the undepressed position for reception. YOR Enables automatic volce-actuated transmitter swit- ching in SSB, AM and FM modes; and semi break-in keying in CW mode. The controls affecting VOX oper- ation are located in the top access panel, DIM Dims the brighmess of the display and meter lamp for comfortable viewing in the dark, Display Dim Level Adjustment The brightness of the dim selection is adjustable by holding the FAST button while turning the CLAR control, (3) METER Selector This selector determines the function of the mul- meter during transmission. The meanings of the ab- breviations are as follows: ALC = relative Automatic Level Control voltage COMP =RF speech compressor level (in dB, for SSB modes only) PO = RF Power Output (watts) SWR = Standing Wave Ratio (forward: reflected) IC = Final amplifier collector current (Amps) УСС = Final amplifier collector voltage. The meter indicates the selected parameter during transmission, and signal strength in S-umits during re- ception (on the main receiver). Each S-umtis approx- imately 6 dB. (4) AGC Selector Selects main receiver Automatic Gain Control de- cay ume for most comfortable reception, or disables page 1) —— a 3. Controls & Connectors - Front Panel Controls receiver AGC (off). Normally this switch is set to the MED position. Strong signals will cause distortion if this selector is set to OFF. (5) FRONT END Use this selector to set the optimum receiver front end characteristics. The NOR position activates the inter- nal rf amplifier, for maximum receiver sensitivity on a quiet band. The IPO position bypasses the rf amplifier and feeds the received signals directly to the first mixer. The other positions insert 6-, 12- or 18-dB (1,2 or 3 S-units) of attenuation before the mixer, to suppress band noise and possible overload from very strong signals. If the optional BPF-1 Bandpass Filter Unit is installed, the functions of this selector, for the sub receiver, may be controlled either in parallel with the main receiver via this selector, or independently via the selector on the BPF-1. (6) RX MIX =9)- MONI The inner RX MIX control adjusts the relative balance of receiver audio between the two receiver channels during dual reception. The outer MONI control adjusts the audio volume of the CW sidetone, and transmit RF monitor during transmission, when activated by the gray button with the same name. (7) MIC -9- RF PWR The inner MIC control adjusts the microphone input level for (non-processed) SSB and AM transmission. The outer RF PWR control adjusts the transmitter output power in all modes. The adjustment range is from less than 20 to 200 watts, except in AM mode, where it is from about 3 to 50 watts. (8) PROC 9 DRIVE The inner PROC control sets the compression (input) level of the transmitter RF speech processor in SSB modes, when activated by the gray button with the same name. The outer DRIYE control sets the carrier level for CW and AM transmission. Also, when the speech processor is used in the SSB modes, this control sets the processor level. In each case, the ALC function of the meter should always be selected when setting this control, to avoid overdriving the transmitter final amplifier. (9) SQL © NB The inner SQL control sets the signal level threshold at which receiver audio is muted (and the green BUSY LEDs turn off), in all modes. This control is normally kept fully CCW, except when scanning, and during FM operation. Both main and sub receivers are affected. The outer NB control adjusts the blanking level when the noise blanker is activated during reception, for the main receiver. If set very far clockwise, receiver audio may be distorted. (10) AF -9- RF The inner AF gain control adjusts the audio volume of the receiver(s) in the speaker or headphones. The outer RF gain control adjusts the receiver signal level in front of the main receiver 1st mixer (via PIN diodes), and also the gain of the main receiver IF amplifiers. This control is normally set fully clockwise for maximum sensitivity. When rotated counterclock- wise from maximum, the S-meter minimum deflection point will move up the scale. The peak deflection for a particular signal will remain the same if it is greater than the level set by this control, but the main receiver will be insensitive to weaker signals. This control also affects the SQL setting for the main receiver, and should be preset fully clockwise when setting the squelch threshold for vfo A or a recalled memory. This control does not affect the sub receiver. (11) MIC This 8-pin jack accepts the MD-1pg or MD-lcs Desktop Microphone or the MH-1g8 Handie Scanning Microphone. MIC pinout is shown on page 7. Proper microphone input impedance is 500 to 600 ohms. (12) KEY This !/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or output from an external electronic keyer. You cannot use a 2-contact plug in this jack. Pinout is shown on page 7. Key up voltage is 5 V, and key down current is 0.5 mA. There is another jack with the same name, connected in parallel with this jack, on the rear panel. (13) PHONES This !/4-inch, 3-contact jack accepts either mon- aural or stereo headphones with a 2- or 3-contact plug. When a plug is inserted, the loudspeaker is disabled. With stereo headphones such as the optional YH-77ST, you can monitor both receiver channels at the same time during dual reception. In this case, the PHONE switch (page 17) in the top access panel selects mixed, separate or monaural headphone operation. (14) Push Switches PROC This gray button enables the RF speech processor for SSB transmission. Processing level is set by the control with the same name. While activated, the LED above this button glows orange. page 11 3. Controls & Connectors - Front Panel Controls MONI This gray button enables the transmit (RF) monitor in all modes (except CW, in which thé monitor function is always on, to produce the sidetone). Audio level (relative to the main AF control) is set by the control with the same name. The LED above this button glows prange while activated. NB 42 NB-W These buttons activate the main receiver noise blankers. Press the NB button to blank short pulse noise such as from automobile ignitions, power lines and switching transient spikes. Press the HB-W button to blank long pulse noise, such as the “Woodpecker” over-the-horizon radar. The LEDs above gach button glow green while activated, Blanking level for both blankers is set by the control with the same name, А-В This button transfers data from the main display (either the main vfo (A) or a recalled memory channel) to the sub vio (В), overwriting any previous contents in the sub vfo, Use this key to instantly set both main and sub receivers to the same frequency and mode, A=B This button exchanges the contents of the main display (either the main vfo (A) or a recalled memory channel), and sub vio (B). No data 15 lost. M= YFO-A Pressing this button momentarily displays the con- tents of the currently selected memory channel for three seconds. Holding this button for for 1/>-second copies the data from the currently selected memory to page 12 — 1 4 the main vio (A), as two beeps sound. Previous data in the main vio 15 overwritten. RPT When operating in the FM mode on the 29-MHz band, this button activates standard hf FM repeater operation, Pressing this button once or twice while receiving causes the transmit frequency to be shifted 100 kHz below or above the receiving frequency, res- pectively. An 88.5-Hz subaudible tone 1s also trans- mitted automatically at a low level when using this feature, to allow access to repeaters that require it. Pressing this button a third time cancels repeater shift operation. M CK (Memory Check) This button allows display of the contents of the memory channels without disturbing operation. When pressed, M CK is displayed just above the channel num- ber. The contents of each memory channel can then be checked on the sub receiver display by rotating the MEM selector. Empty memory channels display as two deci- mals, with no frequency digits. Press this button again to cancel memory checking. SPLIT This button activates split frequency operation be- tween the main display (either the main vio (A) or a recalled memory channel), used for transmission, and the sub vfo (B), for reception. The SPLIT indicator on the display is lit while this function is active. DUAL This button activates dual-channel reception with the main and sub receivers. When this function is ac- | A 3. Controls & Connectors - Front Panel Controls tive, DUAL is displayed in an orange box at the left edge of the display. DOWN & UP Pressing either of these buttons momentarily steps the operating frequency down or up 100 kHz, respec- tively. Pressing and holding the FAST button while pressing one of these buttons steps down or up 1 MHz. Continue holding either button for repeated stepping. NOTCH This button activates the IF notch filter for the main receiver. The frequency of the notch is set by the con- trol with the same name. The LED above this button glows green while the notch filter is active. The notch filter does not affect the sub receiver. APF This button activates the Audio Peak Filter during CW operation with the main receiver. The peak fre- quency is set by the control with the same name. The LED above this button glows green while the audio peak filter is active. Sub receiver operation is unaf- fected. УРО-А > М Pressing and holding this yellow button for !/2- second transfers (writes) the current main operating data from the main vio (A), or a recalled memory, to the currently selected memory channel, overwriting any previous data stored there. Also, pressing and hold- ing this button after recalling a memory, without first retuning, causes the memory channel to be “blanked”, and repeating the process restores the blanked memory. VFO/MEM This button toggles main receiver operation be- tween the memory channel and the main vio (A). Either VFO, MEM Or M TUNE is displayed to the left of the main frequency display to indicate the current selection. If a displayed memory has been retuned, pressing this but- ton returns the display to the original memory contents, and pressing it again returns operation to the main vfo. (15) MODE These seven momentary buttons select the oper- ating mode, indicated by the LED in each button. Note that pressing the RTTY and PACKET buttons multiple times will switch between the possible modes of emis- sion that can be used by these digital modes (LSB and USB for RTTY, and LSB and FM for packet). (16) FAST For fast tuning, press and hold this button while rotating the main or sub tuning knobs or pressing the UP or DOWN button to increase the tuning rate ten times. See the table on page 20 for all available steps. (17) Main (VFO-A) Tuning Knob This knob adjusts the operating frequency of the main vfo (A) or a recalled memory. Tuning increments are normally 10 Hz (100 Hz in AM and FM modes). When the FAST button is held, the increments are ten times these sizes. The markings on the knob represent 50 increments each, and one full turn of the knob provides 1,000 increments (10 kHz, or 100 kHZ in AM/FM). page 13 3. Controls & Connectors - Front Panel Controls (18) MAIN VFO-A RX & TX LEDs These lamps indicate the transmit/receive status of the main tuning knob and display. When the green RX lamp is lit, the receiving frequency is under control of the main knob and display (either vfo (A) or a recalled memory channel). When the red TX lamp is lit, the transmitting frequency is under control of the main knob and display. (19) Lock This button toggles locking of the main tuning knob to prevent accidental frequency changes. LOCK is dis- played in a red box above the main frequency when active (the knob can still be turned, but it does nothing). Press again to re-enable the tuning knob. (20) BANDWIDTH These four momentary buttons select the 2nd and 3rd IF filters for the receiver (except in the FM mode). In AM mode, either 2.4-kHz or 6-kHz bandwidths are selected by pressing the 2.4K button (off = 6-kHz). The selectivity provided by these selections can be further enhanced by installing optional filters (page 40). See the diagram on page 23 for the available filter combina- tions. The sub receiver uses only 500-kHz (optional) and 2.4-kHz selections. (21) BAND (Keypad) The keypad provides one-touch band selection, or digital frequency entry. Normally, pressing one of the ten white numbered keys selects the corresponding (MHz) amateur band for operation (and pressing the SUB button first and then another key selects the band for the sub vfo. However, if the ENT key is pressed first, the yellow labels on the keys become effective, for entering any frequency one digit at a time. If you press the white numbered key for the band your are already on, you will select the alternate subband vfo on that band. See the Operation chapter for details. (22) Sub (VFO-B) Tuning Knob This knob adjusts the sub vfo (B) operating frequen- cy. Tuning increments are the same as described for the main tuning knob. (23) SUB VFO-B RX & TX LEDs These lamps indicate the current status of the sub vfo. When the green RX lamp is lit, the receiving fre- quency is under control of the sub vfo (B). When the red TX lamp is lit, the transmitting frequency is under control of the sub vfo. During dual receive operation, the RX lamps above both tuning knobs are lit. (24) LOCK This button toggles locking of the sub vfo tuning to prevent accidental frequency changes. The red LED just above this button glows when active (the knob can still be turned, but it does nothing). Press the button again to re-enable the tuning knob. (25) NOTCH 9 APF These controls are active only when their functions have been enabled by the corresponding buttons below the sub vfo tuning knob. The LEDs above the buttons indicate when the functions are active. The inner NOTCH control adjusts the IF notch filter frequency. The outer APF control adjusts the frequency of the Audio Peak Filter in CW mode. Both affect only the main receiver. (26) CLAR Tuning Knob This knob tunes the clarifier offset frequency up to +9.99 kHz, when activated by the CLAR RX and/or TX buttons just above it (the 3-digit offset frequency ap- pears in the center of the display when the clarifier is active). Operating details are on page 28. (27) SHIFT -©- WIDTH These controls tailor the IF passband of the main receiver (the main vfo (A), or a recalled memory chan- nel) in all modes except FM. The inner SHIFT control offsets the center frequency of the IF passband from the displayed frequency when turned away from the 12- o’clock position. The outer WIDTH control, when turned counterclockwise from the fully clockwise position, reduces the overall IF bandwidth from the maximum selected by the BANDWIDTH buttons. (28) MEM This detented knob selects the operating memory channel when the memories are active (but not re- tuned). When the vfo or memory tune functions of the main display are active, turning this knob causes the sub vfo display to temporarily show the frequencies of the memories (memory check), without otherwise af- fecting operation. The channel number of the selected memory is displayed at all times at the center right of the display (in front of “CH”). (29) Electronic CW Keyer Controls The KEYER button toggles the internal CW keyer on and off, as indicated by the LED above this button. BK-IN turns full break-in (QSK) CW operation on and off. SPOT turns the CW receiver spotting heterodyne oscillator on and off. The SPEED control sets the repeti- tion rate of the keyer/bug simulator. page 14 3, Controls E Connectors - Front Panel Controls (30) CLAR Pushbuttons Pressing the RX button activates the CLAR knob (below this button), to allow offsetting the receiving frequency temporarily (see (26), above). The TX button provides the same function for the transmit frequency. If both buttons are pressed, the receiver and transmitter are both offset from the original frequency. Pressing the CLEAR button zeros any offset tuned by the CLAR knob, Each memory and vio retains all clarifier settings inde- pendently. (31) TUNER 2-Fosition Pushbutton Pressing this button so that its LED 15 lit places the antenna tuner in line between the transmitter final amp- lifier and the main antenna jack. Reception 1s not af- fected. The tuner is also activated when the START button (below) 15 pressed. (32) START Momentary Pushbutton Pressing this button while receiving in an amateur band activates the transmitter for a few seconds while the automatic antenna ner rematches the antenna for minimum SWE. The resulting settings are automat- ically stored in one of the antenna tuner’s 39 memories, for instant automatic recall later when the receiver 1s tuned near the same frequency. (33) M SCAN Pushbutton Activates scanning of the memory channels. Also used together with the FAST button to seyreset Scan skip status of a recalled memory channel. (34) Right Side LED Indicators The HI SWR LED lights when an impedance mis- match 1s detected at the main ANT jack. Avoid transmiit- fing until me problem has been corrected, The WAIT LED lights while the antenna tuner is tuning, and flashes briefly when changing frequency, as the main cpu sends new frequency data to the anten- na tuner coprocessor: this does not affect opération. The CR TUNE LED 15 a visual tuning indicator for CW réception on the main receiver, which hghts in synch- romzation with a signal tuned to the center of the IF passhand during CW reception. (35) Digital Display The display shows, from left to right, special oper- ating status (CAT SYSTEM, DUAL, SPLIT or GEN (eral coverage), VFO, MEM or M TUNE mode of the main receiver; main receiver operating frequency, clanfier offset, memory channel number; and sub vfo mode and fre- quency. (36) Left Side LED Indicators The TRANSMIT LED glows red when the transmitter 15 activated. The MAIN BUSY and SUB BUSY LEDs clow green when the main or sub vfo squelch is open, respectively, (37) Meter The 7-function multimeter normally indicates main receiver signal strength on the top scale, and one oË six parameters (selected by the METER selector) during transmit on the lower scales. page 13 3.

There i5 no need to turn this switch off unless you plan to store the transceiver for a long period without use. (10) PHONE Slide Switch This switch selects between three possible modes of dual-receive audio when stereo headphones are con- nected to the front panel PHONES jack. The aix (mixed) mode is à combination of the other {wo modes described below: audio from both receivers can be heard in each ear, but the sub receiver audio 15 attenuated in the left ear, and the main receiver audio 1s attenuated in the right. In the st (stereo) mode, audio from the main recei- ver 15 heard only in the left car, and audio from the sub receiver is heard only in the right ear. In the mono (monaural) mode, audio from both main and sub receivers is combined and heard the same in both ears (as from the loudspeaker when headphones are not used). Note that both receivers must be activated by the DUAL button on the front panel, and the RX MIX control on the front panel must be set near the center position, to hear both receiver channels. (9) MARK Slide Switch Set this switch en to activate the internal 10-kHz marker generator, for testing or calibration purposes. For normal receiver operation, this switch must be off. This switch does not affect dual-channel audio from the AF OUT jack on the rear panel, which should be processed by an external stereo amplifier. Power Up Selections By pressing and holding certain combinations of keypad keys while switching on the FT- 1000, you can perform several functions and make some simple settings, “To reset the microprocessors and clear all memories, turn the transceiver off, and then press and hold the SUB and ENT keys at the lower corners of the keypad while also pressing the POWER switch. Normally there should be no need to do this, but it is provided for servicing purposes, to return all memories and other settings to their default states. Note that it is not necessary 10 turn off the memory backup to reset the microprocessors. To perform the “Las Vegas” diagnostic test of the display and its microprocessor, and to check the ROM version of your transceiver, press and hold the 1.5 and 7 MHz band keys (yellow-labelled 1 and 3 keys) at the upper comers of the keypad while switching the power on. This procedure will not erase any memorized data. After testing the display segments, “YAESU” will be displayed, followed by a ROM versión number. After a few seconds, the display will return to normal operation. | Pressing the 29 MHz band key (yellow-labelled 0 key) while switching on the power causes the 10-Hz digit on the main and sub vfo displays to be blanked. Repeat the same step to unblank it. Pressing the 10, 14 and 18 MHz band keys (yellow-labelled 4, 5 and 6 keys) simultaneously while switching the power on toggles the manner in which the displayed frequency is affected when changing modes. In its default state, switching to and from CW, packet or RTTY modes causes the display to change by the amount of | offset selected by the OW PITCH and PKT/RTTY DIP switches in the top access panel. After holding these keys | while switching power on, the display will continue showing the same frequency when changing to and from | these modes, However, the actual BFO (carrier) offsets, set by the DIP switches, relative to the display and IF bandpass are unaffected, regardless of either display state. — — page 17 3.

Switch $1001 on the RF Unit must also be set to the E BPF position to use the BPF-1 (page 9). (2) GND Terminal Post Use this terminal to connect the transceiver to à good earth ground, for safety and optimum perfor- mance. Use a large diameter, short braided cable. (3) ANT Coaxial Jack Connect your main antenna here, using a type-M (UHF, PL-259) plug and coaxial feedline, This antenna is always used for transmission, and is also used for reception unless a separate receive antenna 1s also used for the main receiver. The internal antenna tuner affects only the antenna connected here, during transmission. (4) RX ANT Phono Jack This antenna jack 18 for a separate receive-only antenna, activated when the switch with the same name on the front panel is pressed. If the BPF-1 option 15 not installed, an antenna connected here can be used by both the main and sub receivers. If the BPF-1 1s in- stalled, internal switch 51001 on the RF Unit deter- п о о mines whether this jack is used, or the SUB RX ANT on the BPF-1 instead. See the diagram on page 29. (5) TX GND Phono Jack (normally disabled) When enabled, this output jack connects inside the FT-1000 to à set of relay contacts which short together (to chassis ground) whenever the transmitter 15 active. This allows transmitreceive switching of an external device such as a linear amplifier, This jack is disabled at the factory to avoid the clicking of the relay when it is not used. To enable the jack when you are connecting a linear, move switch S1002 (shown on page 9) to 1ts ON position. Maximum ratings for these relay contacts are 500 mA @ 125 VAC, 300 mA @ 220 VDC or 2 A @ 30 VDC. Before connecting an external device, make sure its switching requirements will not exceed these limits. If your amplifier requires higher current, or has higher voltage switching requirements, an external switching device such as the Yaesu FRB-757 Relay Box must be used, and may be connected here.

This bandwidth provides the best fidelity for SSB reception, so should be used unless interference from stations on adjacent frequencies becomes a prob- lem (as described later). Adjust the AF control for comfortable volume on signals or noise in the loudspeaker or headphones. Press the large UP and DOWN buttons below the keypad to step around the band in 100-Hz steps, and then tune around the band a bit with the main tuning knob. For faster (x10) tuning steps with either the tuning knob or UP and DOWN buttons, press and hold the FAST button at the lower left side of the knob (all available tuning steps in each mode are shown in the table below). If your microphone has UP and DWN buttons, you can press them to tune in 10-Hz steps, and if it has a FAST button, you can use it to duplicate the function of the key with the same name on the front panel.

Pressing the same band key again switches you back to the frequency you were on before. What you have here are two completely independent vio selections for each band, selectable by each band’s keypad key, You can tune, select a mode and a bandwidth for each of these two vio selections in each band, and they wall be page 20 4. Operation - Getting Started Tutorial remembered until you return to this “subband” selec- tion. Try this now: assuming you have already set one of the vio selections to the SSB portion of the band (and in an SSB mode), press the keypad key for that same band, tune to the low end of the band, and press the CH button to the left of the tuning knob. You can consider this your CW subband vfo. Now press the keypad key for the same band again several times, and notice that operation shifts back and forth between the SSB and CW subband vfo frequencies and modes. You'll be pleased to know that you can also select different IF bandwidths for the two subbands, just as you did above with the modes (and even different clarifier settings). Note that this dual subband feature is not related to the vío A/B scheme — both main vfo A and sub vfo В support their own dual subbands, independently of one another. More on that later, Keypad Frequency Entry One other important tuning feature to try before going on is numeric keypad frequency entry. To do this, pick a new operating frequency, say, 14.25000 MHz, and enter it on the keypad as follows: Press the ENT key at the lower right corner of the key- pad (the leftmost operating | 3 ss 1 [7 frequency digit will blink). E db [| ‘Then referring to the yellow | [** «)[** s][* à numbers on the keypad, en- B ; [= | [28 ter the digits of the new fre- = = suB — [* o ENT quency, from left to right (1-4-2-5-0-0-0), followed ‘by the ENT key again. As you enter the numbers, the Next digit to be entered will blink on the display, You Can use the DOWN and UP buttons below the keypad to reposition the blinking digit location as desired (but ignore the direction labels on these buttons). Only when you press the ENT key the second time will the operating frequency actually change, so if you decide to remain on the original frequency after starting to key in a new one, you can cancel any entered digits by pressing the CE key (“Clear Entry”, the yellow label at the lower left corner of the keypad) instead of the ENT BAND Ñ key. Note that, to enter frequencies below 10 MHz, you must key in the leading zeros. That's all there is to tuning the main vio (A). The sub vio (B) has a lot more features of 15 own, which we'll look atin detail later. First, however, let's look at some other important receiver features, General Coverage Reception You may have already noticed that if you tune out- side one of the amateur bands (actually, outside of the 500-kHz segment that includes each band), GEN appears in à box at the left side of the display. On such frequen- cies, the transmitter (and antenna tuner) are disabled, If you try to transmit, the TRANSMIT LED will blink. Also, such frequencies are ignored by the band selection keys (including the alternate subband fea- ture): so if you wne a vio to a frequency outside of a ham band, you will have to store it in a memory (as described on page 32) if you want to be able to recall it quickly later. Otherwise, as soon as you press a band key, the general coverage frequency will be lost as the vio reverts to the (ham-band) frequency it was on when the band was last changed. Once you become familiar with the memories, you will find this really doesn't present a problem, as each memory can be tuned just like a vfo, and stored into another channel without having to go through a vfo. Aside from the above, general coverage reception provides all of the features available on ham frequen- cies, including dual channel reception, digital modes and diversity reception, described on the following Pages. page 21 4. Operation - Dealing with Interference Dealing with Interference The FT-1000 includes a wide range of special fea- tures to suppress the many types of interference that may be encountered on the hf bands. However, real world interference conditions are constantly changing, so optimum setting of the controls 1s somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls. Therefore the following information should be considered only as general guidelines for typical situations, and a starting point for your own experimentation. The descriptions of the use of each control are arranged in the order that you would usually make them after changing bands. The possible exception to this 18 if strong pulse noise is present, such as from the “Woodpecker”, in which case you may need to activate the noise blanker (described on this page) before you can make other adjustments. Front End Selection Perhaps the most important consideration for op- timum receiver performance, after you have selected a particular band, 1s the receiver front end selection, The best selection will depend on background noise at the time, the presence or absence of strong signals, and whether or not you want 10 hear very weak signals. It the front end is set for too much gain, background noise will make listening difficult, and very strong signals on other frequencies may cause intermodulation interter- ence, masking weaker signals. On the other hand, if the front end 15 set for too little gain (or too much atténua- tion), very weak signals will not be heard. The NOR setting of the FRONT END selector activates a constant-gain, quad push-pull FET amplifier for maxi- mum sensitivity. However, if background noise causes the S-meter to deflect on clear channels, turn the FRONT END selector clockwise until the S-meter drops below S-1 (the white area at the left end of the top meter scale). This setting optimizes the trade-off between sensitivity and interference immunity. Also, once you have tuned in a station you want to work, you may want to reduce sensitivity further (or add апепцапоп) Бу turning the FRONT END control to a more clockwise setting. This can make reception of the desired station more comfortable, important especially in long OSOS. KF Gain Setting When tuned to a moderate strength signal, 1f low level background noise 1s still present after setting the FRONT END selector, try reducing the RF gain control from the fully clockwise positon, This reduces the signal input to the first mixer via a PIN diode attenuator page 22 and causes the minimum S-meter reading to move up the scale, often clearing up the background noise and putting the desired signal more “in the clear”. Remem- ber, however, to return this control fully clockwise when you want to receive weak signals, or read low levels on the S-meter. See also the Note box below. AGC (Automatic Gain Control) Selection When tuning around the band looking for signals, the AGC selector is usually best kept in the FAST position, to allow the receiver gain to recover quickly after tuning past strong signals. However, once you have a station tuned in, SSB reception will usually be more comfortable if you switch to the MED or even SLOW position (keeping the receiver from picking up low- level noise during pauses in speech). However, for CW reception, when several signals are present in the pass- band, the FAST or even OFF positions can avoid AGC “pumping” (gain fluctuations) caused by strong un- desired signals. For AM, the SLOW position 1s usually better, and for 300-baud packet and RTTY/AMTOR, the FAST or OFF positions will usually give the fewest errors/retries. Note: The AGC OFF position disables the over- load-protection normally provided by the AGC circuitry, If the RF gain control is left fully clock- wise in this condition, the RF and IF amplifiers can be easily overloaded (causing distortion) when a strong signal is received. Correct the overload either by setting the AGC selector to another position, or by turning the RF control counterclockwise to manually set receiver gain to a comfortable level. Noise Blanker Selection and Setting The two noise blanker circuits in the FT-1000 are provided for two different types of pulse noise. The NB button activates the narrow pulse blanker, for short pulse noise such as from switching rransients, auto- mobile ignitions and power lines. This blanker can sometimes also reduce the level of static crashes from electrical storms. The NB-W button activates the wide pulse blanker, for longer duration man-made pulse noise such as the “Woodpecker” over-the-horizon radar. If you hear any of these types of noise, just press either the NB or NB-W button so that the green LED above it lights, and turn the NB control clockwise. If the blanker seems to distort a signal you're listening to, reduce the setting for optimum readability, 4. Operation - Dealing with Interference IF Bandwidth and Shift Adjustment (not used in FM mode) Once you have tuned in a signal you are going to listen to for a while, if you hear interference from stations on nearby frequencies, use the BANDWIDTH but- tons and then the SHIFT and WIDTH controls to suppress the interference. Their use varies somewhat from mode to mode. In general, however, you will want to press the LOCK button beneath the tuning knob before adjusting the SHIFT and WIDTH controls, as accidentally retuning would invalidate your settings (particularly in narrow-bandwidth modes). When you are ready to re- tune to a new frequency, press LOCK again to release it, and return the SHIFT and WIDTH controls to their default positions (centered, and fully clockwise, respectively). In the SSB modes, the 2.0K bandwidth button can sharply cut interference from unwanted signals on either side of the desired signal (although with some necessary loss of fidelity). The WIDTH control can also be turned counterclockwise to reduce the IF bandwidth more gradually, and then the SHIFT control can be turned left or right from center to shift the center fre- quency lower or higher, as depicted at the right. In AM mode, if the BANDWIDTH LEDs are all off, the 6-kHz AM wide bandwidth is selected. This gives the highest fidelity, and is best on strong AM signals (and particularly music).

Operation - Dealing with Interference controls in this wide bandwidth are subtle, but they can be helpful in fine tuning the audio characteristics. For weaker AM signals, or where adjacent channel inter- ference is present, the 2.4K bandwidth offers a com- promise between interference rejection and fidelity. In this case the SHIFT and WIDTH controls can be used to improve fidelity. However, even better reception of AM signals under these conditions can usually be had by switching to an SSB mode (whichever gives the clearest reception), and superb reception of weak sig- nals is often possible using diversity reception, des- cribed on page 30. In RTTY anil AMTOR modes, the wider bandwidth selections are fine for tuning around, but the 250 or 500 (Hz) bandwidths will generally give the best copy with narrow shifts. If you have the RTTY DIP switches in the top panel set to match your tnc/terminal unit (see page 16 ) you should not need to adjust the SHIFT control at all, and the WIDTH control should only be adjusted with a great deal of care (to avoid loosing the contact). See the section on digital modes later in this manual for more details. For 300-baud packet, use the 500 (Hz) bandwidth, and make sure the PKT DIP switches in the top panel are set to match your tnc/terminal unit (or see the section on HF Packet on page 34). The WIDTH control must be set fully clockwise, and the SHIFT control may need to be fine tuned a few clicks either side of center for optimum copy of weak signals. Experiment with the SHIFT setting on a busy packet channel, and then note the optimum setting for all future hf packet operation (it will be the same unless you replace your tnc or recalibrate the input tones). If you have the BPF-1 option installed and two antennas connected, you will definitely want to try diversity recepuon of HF packet signals (page 30). In the CW mode, the 2.0K or 2.4K bandwidth is often convenient to give “a wide view” of the band when tuning around, but once a signal of interest has been found and centered in the passband, the 500 or 250 (Hz) selections are much better. Then the APF (Audio Peak Filter) can be activated, if needed, for even nar- rower (audio) bandwidth. More details of CW opera- tion are provided in the box below, and in the next section on transmission. IF Notch Filter (not used in FM mode) After tuning in a desired signal and adjusting the IF bandwidth and shift, if heterodyne interference 1s heard, activate the IF notch filter by pressing the NOTCH button and adjusting the control with the same name to null the heterodyne. Note that if the interfering het- erodyne is more than about 1.2 kHz away from the center of the passband, the notch filter may be unable to null it. In this case, switch the notch filter off, and readjust the IF bandwidth and shift so that the heter- odyne 1s outside of the passband. IF Notch Filter Adjustment Héterodyne Demi red > ra — m LF Bandpass Special Tips for CW Reception: Pitch Setting and Spotting The FT-1000 can be set for 400-, 500-, 600- or 700-Hz CW pitch, by setting the Cd PITCH DIP switches in the top access panel. With the CW SPOT button pressed, set these to the tone your prefer, according to the table on page 17. This selection affects the audio frequency of the spotting oscillator, which sounds a tone in the receiver when you press the SPOT switch near the lower right corner of the front panel (relative tone volume can be adjusted by the MONI control). The frequency of this tone is also (exactly) the frequency that the IF center frequency and display are offset from the true carrier frequency during CW reception, which means that you can use this switch when tuning in another station to zero beat with him, so that when you transmit, your signal will be on exactly the same frequency as his. When you have a station tuned so that his signal produces the same audio note as the spotting oscillator, you will know that his signal is centered in your IF passband, which ensures that you will not loose track of his signal when switching to a narrower filter or acuvatng the APF. Of course you should turn off the SPOT switch to copy his signal. In addition to the spotting oscillator, the CW TUNE LED at the right end of the display provides a constant visual indication of any signal at the center of the IF passband (if not too weak), You can use this LED to tune in a signal just by tuning so that the LED glows in sync with the signal of interest. page 24 - = 4. Operation - Transmitting Transmitting The transmitter can be activated within the 500-kHz segment of any of the hf amateur bands, and from 28 to 30 MHz. When tuned to any other frequency, GEN is displayed at the left side of the display, and the trans- mitter is disabled. However, you are responsible to restrict your transmissions to those frequencies on which you are authorized to do so. You should also restrict transmissions to the frequencies for which your antenna 1s designed. Attempting to transmit outside of an amateur band segment will cause the red TRANSMIT LED to the right of the meter to blink. The transmitter is also temporari- ly inhibited when stopping memory scanning (des- cribed later), as pressing the PTT switch while scanning just causes the scanner to stop. Whenever the transmitter is activated, the FT-1000 automatically detects any reflected power that might appear at the main antenna jack (as a result of an impedance mismatch), and disables the transmitter if too much reflected power is found (in which case the red HI SWR LED at the right side of the display will be lit). Although this protection system should prevent any damage to the transceiver, we still recommend that you never activate the transmitter without having a proper antenna connected to the main ANT jack. Automatic Antenna Matching The automatic antenna tuner in the FT-1000 makes even first-time transmitter setup very simple. After you have used it once on your favorite bands, it will be able to recall previous settings from memory (the tuner has AY of its own) during reception, whenever you tune to the same part of the band again. When you use the tuner the first time on an antenna, we recommend you set the RF PWR control to around the 9-o'clock position, to minimize interference you might cause others, and also to minimize stress on the tuner, feedline and antenna (in case there 1s a high SWR). All you have to do before- hand 15 to make sure of the frequency you will transmit on, and check that it is clear of other signals. Also, if you want to visually monitor the tuner's action, set the METER selector to the SWR position. l the orange TX LED above the main tuning knob is not lit, press the SPLIT button below this knob to disable split frequency operation for now. After making sure the channel is clear, press the START button near the upper right corner of the front panel, The green TUNER LED will come on, indicating the automatic tuner is activated, and the orange WAIT LED at the right end of the display will light for (up to) a few seconds while the tuner seeks the proper match- ing settings (and, if monitoring SWR on the meter, you should see the tuner select the lowest possible reading), When the WAIT LED turns off, you are ready to transmit (assuming the HI SWR LED didn't light). > CAUTION If the red HI SHR LED lights ar any time, the tuner 15 unable to match your antenna to the transmitter at the displayed frequency. You will have to tune to another frequency, or repair or replace your antenna or feedline. After using the antenna tuner, the green TUNER LED will remain on (unless you press the TUNER button to turn it off), and the orange WAIT LED will occasionally flash when you change frequency, indicating that the main microprocessor is reporting the frequency change to the tuner coprocessor (reception is unaffected). If the tuner coprocessor finds, by comparing the frequencies in 1ts own memories, that you have tuned far enough to possibly require rematching, it will reset itself to the new range (if it has any previously stored settings for the new range). However, when you first connect a new antenna, the tuner will not have the correct settings stored in these memories, so you will need to “train” the tuner, by pressing the START button whenever you Change to a new band or frequency range (for this antenna). SSB Transmission To transmit in LSB or USB mode: * Make sure the appropriate mode indicator is lit, and set the METER selector to the ALC position. * If this is the first time you are transmitting SSB with the FT-1000, preset the MIC and RF PWR controls to about the 12- 0 clock position, and make sure the YOX is Off (button out). * Check the RX and TX LEDs above the tuning knobs to determine which frequency you're going to transmit on, and make sure the GEN box is not showing to the left of the main frequency display. * To transmit, just press the PTT (push-to-talk) switch on your microphone, and talk. To determine the optimum setting of the MIC control for your microphone, adjust it while speaking into the microphone (at a normal level) so that the meter de- flects to about midrange on voice peaks (the upper end of the blue ALC range). Once found, this setting can be left as it is unless you change microphones, = page 25 4. Operation - Transmitting You can switch the METER selector to the PO position and adjust the RF PWR control for more or less output, from about 20 to 200 watts (on the second meter scale from the top), as desired. However, you should always use the lowest possible power output to maintain reli- able communications — not only as a courtesy to other stations, but to minimize the possibility of causing RFI and TVI, and to maximize the life of the equipment. Transmitter Monitor The transmitter monitor is actually a separate recei- ver circuit which picks up a sample of your transmitted RF signal, allowing you to hear accurately how the signal sounds. This feature is very helpful for setting up the speech processor controls, among other things. However, audio feedback of your signal from the loud- speaker to the microphone is likely if you attempt to use the monitor without headphones, so you should plug in your headphones now, if you have them. Activate the monitor by pressing the gray MONI but- ton (below the AF control) so that its orange LED lights, and adjusting the MONI control beneath the meter for comfortable volume while transmitting. "RF Speech Processor Once the proper MIC control setting has been deter- mined, you can activate the RF speech processor to increase the average power of your signal. + Set the METER selector to the COMP (speech processor compression) position, and press the gray PROC but- ton (at the left end of the row of buttons along the bottom) so that its orange LED lights. * Now while speaking into the microphone, adjust the PROC control for a compression level of 5 to 10 dB on the COMP scale of the meter (the second scale from the bottom). If you have the monitor activated, you will be able to hear the effect of the compression on your signal. In any case, we do not recommend higher compression settings, as your signal will become less readable. + Finally, move the METER selector back to the ALC position, and (without touching the MIC control set- ting) adjust the DRIVE control so that the meter reads in the upper end of the blue ALC scale on voice peaks. VOX (Voice-Actuated T/R Switching) VOX operation allows you to activate the transmit- ter in any voice mode merely by speaking into the microphone, without having to press the PTT switch. For the VOX circuit to operate properly, three con- trois in the top access panel must be set to match your microphone and the acoustic environment of your sta- tion. Once set, these controls should not require re- adjustment unless you change your microphone or sta- tion location. + First make sure the receiver is set for normal volume on a clear channel, and preset the VOX GAIN control in the top access panel fully counterclockwise. Also preset the ANTI-TRIP and DELAY controls in the top access panel to their 12-o'clock positions. * Set the RF PWR control fully CCW (to avoid creating interference while you set up the VOX controls). + Now press the VOX switch near the upper left corner of the front panel, so that its green LED is lit. * Without pressing the PTT switch, speak continuous- ly into the microphone while slowly advancing the VOX GAIN control (in the top access panel) clockwise, just until your voice activates the transmitter. + Now speak intermittently into the microphone, and note the “hang time” between the moment you stop speaking and when the receiver is reactivated. This period should be just long enough so that the trans- mitter remains keyed between words, but drops back to receive during pauses. Adjust the DELAY control, if necessary, for comfortable hang time. The ANTI-TRIP control probably needs no adjust- ment, but if you find that, with the microphone in its normal operating position, receiver audio from the loudspeaker trips the transmitter, advance the ANTI- TRIP control more clockwise. On the other hand, 1f transmitter keying with the VOX keying seems slug- gish or unstable when you speak into the microphone, try a more counterclockwise setting. CW Transmission There are several types of CW transmission avail- able with the FT-1000. All require, of course, that you have a CW key or keyer paddles connected to either of the KEY jacks on the front or rear panel (with a 3-contact plug). Initially, you will need to set the DRIVE control to determine its setting for the proper ALC level, but after that you can use the RF PWR control to set your output power. * Begin by setting the METER selector to the ALC posi- tion, and preset the RF PWR control to about 12 o’clock and the DRIVE control fully counterclockwise. Of course you must select the CW mode, if you haven’t already, and for now, make sure the KEYER and BK-IN switches near the lower right corner of the front panel are both off (out). * Press the VOX button to turn on the VOX circuit, which provides automatic transmitter activation when you close your key. page 26 4. Operation - Transmitting + Now close your key, and advance the DRIVE control 50 that the meter indicates center scale. This 15 the proper ALC level for CW operation. * Adjust the MONI control, if necessary, for comfort- able level on the CW sidetone. * Now you can switch the METER selector to the PO position and adjust the RF PWR for the desired level. 1f you change it much, return the METER selector to ALC and touch up the DRIVE setting, if necessary, to keep the ALC reading in the safe zone. * Release the key to return to receive. Courtesy of the VOX circuitry, you are now using semi break-in CW, in which the transmitter remains activated except during pauses in your sending, You can set the “hang time” during which the transmitter remains on after you stop sending, by adjusting the DELAY control in the top access panel. However, if you prefer full break-in (Q5K) opera- tion, in which the receiver 1s activated between each dot and dash, simply press the BK-IN switch. Using the Internal Electronic Keyer You will need to connect keyer paddles to one of the KEY jacks to use the kever. * Once the transceiver has been set up for CW trans- mission as just described, you can activate the keyer with the KEYER pushbutton near the lower right cor- ner of the front panel (its green LED should hight). + Now squeeze the paddles, and adjust the SPEED con- trol for the desired speed (if you are using the bug simulator mode, described in the box below, don’t squeeze both paddles: just press the dit paddle). If the dot:dash weighting is not to your preference, see the table on page 16 to set the WEIGHT DIP switches in the top panel. If you prefer a higher or lower sidetone pitch, see page 24 and the Pitch table on page 17. You can use the keyer for both semi and full break- in keying, as described in the previous section. AM Transmission Transmitter setup for the AM mode 15 essentially che same as for LSB or USB, except that you must avoid overmodulating, and limit carrier power to 50 watts. * With the AM mode selected, preset the RF PWR and DRIVE controls to the 12-0 clock position. + If you have already set the MIC control as described for SSB transmission, there should be no need to readjust it, Otherwise, preset this control fully coun- terclock wise, + VOX operation can be used in the AM mode, but for now, make sure the YOX switch 18 off, so as not TO confuse adjustments, * The transmit monitor 15 very helpful in setting the correct modulation level, and if you have head- phones on, you should turn the monitor on now. « Close the PTT switch and advance the DRIVE control 50 that the meter deflects just to midrange. « Now, if you don’t have the MIC control already set up, speak into the microphone while advancing this con- rol just to the point where slight movement of the meter can be seen. Don't set it wo far beyond this point or your signal will become distorted from overmodulation if the monitor is on). * You are now ready to transmit. Switch the METER selector to the PO position, and adjust the RF PWR control for the desired output (but not over 50 watts!) Note that the speech processor 1s disabled in the AM mode. You can, however, activate the VOX if desired. FM Transmission For transmission, this is the easiest mode of all. The only control on the front panel you need be concerned about 1s RF PWR. Microphone gain for FM 1s set the separate FMMIC GAIN control in the top access panel, and normally needs no adjustment after leaving the factory. If you receive signals reports of low audio with a strong carrier, you may want to increase the gain. If you notice distortion in the transmit monitor, vou may want to decrease it. Otherwise, we suggest leaving it alone, All you need to do is set the METER selector to the PO position, and adjust the RF PAR control for the desired output while transmitting. If you need full power, keep your transmissions to three minutes or less, with the same time for reception. page 27 4. Operation - Transmitting You can use the VOX circuit for yr switching, if desired, and the transmit monitor to listen to your signal. See also the box below for FM Repeater opera- tion. The FT-1000 includes several features specifi- cally intended for operation on FM repeaters above 29 MHz which use 100-kHz splits. To locate these repeaters, you can ask around the calling channel (29.6 MHz), or you may want to load a block of memory channels (page 32) with 50-kHz frequency multiples from 29.61 to 29.7 — MHz (and FM mode, of course). Then set the squelch so that the receiver is silent on a clear channel, and press M SCAN to scan the memories. | When you find a repeater, press the RPT burton, once for “~" shift (to transmit 100 kHz below your receiving frequency). Pressing it again will select “+” shift, but this is not used above 29.6 | MHz Press it once more to return to simplex. Try a quick identification transmission to make sure you have the shift right (the FT-1000 also | automatically ransmits a low-level 88.5-Hz sub- | audible tone during FM Repeater transmissions, to access those repeater that require it). Once you have made contact through the repea- ter, you can store the frequency, mode and repeater shift settings in memory (page 32) for Clarifier (Rx/Tx Offset Tuning) The three CLAR buttons near the upper right corner of the front panel and the control just below them are used to offset either the receive, transmit or both fre- quencies from their settings on the main display. The three small numbers in the center of the display (just to the right of the man frequency display) show the cur- rent clarifier offset. The clarifier controls on the FT- 1000 are designed to allow you to preset an offset (up to £9.99 kHz) without actually retuning, and then to activate it with the clarifier's RX and TX buttons. Perform the following steps, if you like, to familiarize yourself with the clarifier controls: * Turn the CLAR knob back and forth while watching the center of the display. Notice that a minus sign appears when the offset is negative, * Now, with a non-zero offset displayed, press the RX button several times while watching the display. When the clarifier is activated, RX CLAR appears al the top center of the display, and the main frequency display shifts by the amount displayed for the clari- fier offset. « Press the PTT switch and notice that the transmit frequency remains the same as the original frequen- cy display when the receive clarifier is on. « With the receive clarifier active, turn the CLAR knob again, and notice that both the main frequency and the clanfier offset displays change together. + Now press the clarifier CLEAR key and observe that the offset is cleared to zero, and the main vio fre- quency returns to what it was originally. The transmit clarifier works almost the same way as the receive clarifier, by pressing the clarifier TX button. TX CLAR appears at the top center of the display when the transmit clarifier is active. The offset is only added to the displayed operating frequency, however, when you transmit. A typical application for the clarifier is when you are in contact with a station whose transmitter drifts (or perhaps you didn’t have him quite tuned in when you called him). You don't want to change your transmit- ting frequency, as that would force him to retune — you just want to adjust your receiver, You could proceed as follows while listening to his signal: « Press the clarifier CLEAR button if the displayed clari- fier offset 1s not zero. * Then press the clarifier RX button to activate the receiver clanfier, and carefully retune his signal with the CLAR knob, After you finish your conversation with him, you must remember to press the clarifier RX button again to tum off the clarifier. However, if vou hear another station you want to call right on the frequency he was on, instead of turning off the clarifier, you can just press the TX clarifier button to bring your transmitter onto the same frequency, and make your call (now both the receive and transmit frequencies are offset by the dis- played amount). Keep in mind, however, that you will need to press both the RX and TX clarifier buttons again to turn off the clarifier when you finish. You might also want to clear the offset when done. The FT-1000 actually has an independent clarifier for each vio, on every band and alternate subband, plus one on each of the 99 memories. This means that clarifier TX/RX and offset settings are not carried over when you change bands or memory channels, but rather are stored until you return to that vfo, band, subband or memory again. page 28 - — 4. Operation - Using Sub Vfo B DE Using Sub Vfo B ~ As you might imagine, the sub vfo works in a similar manner to the main vfo, with which you are familiar by now (if you have worked through the pre- vious sections). The major purpose of the sub vfo is to provide simple split (transmit/receive) frequency oper- ation via the SPLIT button, and more importantly, dual- channel reception via the DUAL button. We’ll get into those in a minute, but first let’s look at how to control the sub vio. Frequency, mode, filter bandwidth and clarifier data can be transferred from the main to the sub vio by pressing the A = B button (below the mode buttons), but don’t forget that this will overwrite any settings that were in the sub vfo previously. Also, the contents of the two vfos can be swapped (with no loss of data) by pressing the A = B button. Most selections you can make for the main vfo can also be made for the sub vfo directly, without involving the main vfo at all: the “key” to this is the SUB key (white label) at the lower left corner of the keypad. Sub vfo band (and subband), mode and filter selec- tions can be made just by pressing this key right before pressing another keypad key to select a band, or before a mode button to change the sub vfo mode (displayed above the sub vfo frequency), or before a BANDWIDTH button to select another filter (only 500-Hz and 2.4- kHz filters are available for the sub vfo). When you press the SUB key, the entire display for the sub vfo will blink, afterwhich you have five seconds to press an- other key. Note that to switch subbands in the sub vío, you need merely press the SUB key followed by the key for the same band that the sub vfo is already on. Additionally, you can enter a frequency from the keypad into the sub vio by pressing the SUB key before pressing the ENT key (and the digits of the new frequen- cy you want to enter into the sub vfo, followed by ENT again), Of course you can tune the sub vfo using its tuning knob, and even use coarser (x 10) tuning steps by hold- ing the FAST button (below the left side of the main tuning knob). You can use the large DOWN and UP keys (in both normal and 1-MHz fast steps) for the sub vfo as well, if you just press the SUB key first. About the only things you cannot do with the sub vfo (that you can with the main vfo), are store it directly into a memory, and set the clarifier. For these functions you need to swap it with the main vfo first (push À % B, then hold the yellowVF0-A = M button for !/>-second (to store it in a memory) or set the clarifier, and then press A = B again to return the data to the respective vfos. Dual-Channel Reception By pressing the blue DUAL button, dual receiver operation is activated on the main (A or recalled mem- ory) and sub vfos. DUAL appears in an orange box at the left edge of the display, and the green RX LED above the sub vfo tuning knob lights. NOTE: If the optional BPF-1 bandpass filter option is installed in your set there is no limitation on the relative frequencies of the two vfos if you have set things up as follows: * Internal switch S1001 must be set to the E BPF posi- tion (see the diagram below, and page 9), * Connecta separate antenna to the SUB RX ANT jack on the BPF-1, and | + Press the RXANT switch on the front panel (so its LED is on).

Operation - Using Sub Vfo B Otherwise, the two vos will share the same antenna and frontend bandpass filter, and so should be tuned fairly close to each other for maximum sensitivity (that is, Within 500 kHz or so at low frequencies, or within several MHZz at higher frequencies). Although you may be able to receive on, say, 21 and 28 MHz at the same time, you may find the sub receiver signal attenuated. The RX MIX control adjusts the audio balance be- tween the two receivers. To really take advantage of dual reception, you will want to connect the AF OUT jack on the rear panel to an external stereo amplifier, or stereo headphones to the PHONES jack, and set the PHONE switch in the top access panel to either the mix or the st(ereo) position. Compare these two positions with the RX MIX control set at 12 o” clock and both vfos tuned to signals, to select your preference. With headphones, the st position completely separates the two channels (main in left channel, and sub in right), while the mix position gives you some audio from each channel in each ear, but with the one channel emphasized in one ear, and the other emphasized in the other ear, resulting in a kind of “3-D” spatial audio effect. If you have connected the AUX (high impedance) input of an external stereo amplifier to the AF OUT jack on the rear panel, the front panel AF and RX MIX controls, and the PHONE switch in the top access panel, will not affect your audio. Instead use the controls on your external amplifier. Note that the RF GAIN, SHIFT, WIDTH, NOTCH, APF and AGC functions do not affect the sub receiver (AGC decay rate is automatically selected according to mode). We’ll return to discussing some special applications for dual reception in a minute, but first lets look at split operation. Split Frequency Operation Typical split operation is performed by receiving on the main vfo (A) or a memory channel, and transmit- ting on the sub vfo (B). The special case of FM repeater operation uses some features of its own, and is des- cribed in the box on page 28. To activate split receive/transmit operation, just press the SPLIT button. SPLIT appears in a box at the left edge of the display, and the orange TX LED above the sub vfo tuning knob lights. With the FT-1000, we re- commend that you always activate the dual receiver feature when working split, as this allows you to mon- itor your transmit frequency on the sub vfo (while receiving), as well as the main vfo receiving frequency, so you don’t accidentally “step on” somebody. page 30 Note: For split operation with a separate antenna, you do not need the BPF-1 . In fact, if you have the BPF-1 optioninstalled and you wantto use a separate receiving antenna for split operation, you will have to set things up differently from that described on the previous page for dual reception on separate antennas: * The receiving antenna must be connected to the RX ANT phono jack on the rear panel (not the jack on the BPF-1). * Internal switch S1001 on the RF Unit must be set to the R ANT position. * Press the RXANT switch on the front panel (so its LED is On). Keep in mind that only the main ANT jack can be used for transmission. During split frequency opera- tion, since the sub vfo (B) determines the transmitting frequency, and since only the main ANT jack is used for transmission, the BPF-1 option is inoperative. Diversity Reception This is one of the most exciting types of operation offered by the FT-1000, which is capable of several types of diversity reception: sideband diversity recep- tion of AM signals, bandwidth diversity reception of all modes except FM, and antenna diversity reception of all modes (this last requires the BPF-1 option, and of course, two antennas). Sideband Diversity Reception of AM Signals In this mode, you receive a single AM signal through the two receivers in the FT-1000, each receiv- ing the opposite sideband. Skywave-propagated sig- nals often show considerable phase distortion in this mode, but it gives you a view of the entire passband, from which you can then select the best sideband for listening (or for SWL dxing, you may want to listen to both sidebands at the same time, to get the best copy). On groundwave signals, where the phase of the side- bands is likely to be the same, there 1s an interesting sense of depth to the signal. To tune in a signal using this mode, you should have stereo headphones connected to the front panel PHONES jack, or an external stereo amplifier connected to the rear panel AF OUT jack. » Set the main vfo to either LSB or USB mode, and tune precisely for zero beat on the desired signal. + Press the A» B button below the main tuning knob to copy this mode and frequency into the sub vfo. * Press the mode button to select the opposite side- band for the main vfo (A). * If using headphones, set the PHONE switch in to top access panel to the st position. (J Press the blue DUAL button to activate dual reception. OF using headphones, adjust the RX MIX control to balance the volume of the two receivers. If using an external amplifier, adjust its balance control. If interference is present on one of the channels, you may have to turn the RX MIX control to suppress that channel, Otherwise, try moving the PHONE switch to the mix and mono positions, for different effects (or try settings with similar effécts on your external ampli- tier). Although you don't get the “stereophonic” effect in the monaural mode, the two signals are still mixed, offering the potential for much better copy than in regular AM or even single-sideband ECSS modes, Bandwidth Diversity Reception This mode involves receiving the same signal through two different bandpass filters (the BPF-1 op- tion is not required). The frequency and mode of each vio 15 the same. The main receiver provides a narrow bandpass, and the sub receiver a wide bandpass, result- ing in a spatial perception of the channel, Although any mode (except FM) can be used, CW offers the widest array of choices, and perhaps the most startling effects on crowded channels. stereo headphones or an external stereo amplifier are recommended for this mode, To set up the transcel- ver for bandwidth diversity reception: [1 Select the desired mode on the main vio, and the 2.0- or 2.4-kHz filter (or wide AM - press the 2.4K button if its LED is lit, so that it turns off). (I Tune to the signal of interest (if in CW mode, use the SPOT button to center the signal in the passband). [1 Press the A= B button below the main tuning knob to copy this mode and frequency into the sub vio. O Press one of the narrower BANDWIDTH selections to select a narrow filter for the main vio (A). [11f using headphones, set the PHONE switch in to top access panel to the st position, J Press the blue DUAL button to activate dual reception. ON using headphones, adjust the RX MIX control to balance the volume of the two receivers. If using an external amplifier, adjust its balance control. Notice that we selected the wider filter first, and copied that selection into the sub vio. This allows you lo take best advantage of the extra flexibility of the main vio. For example, try the SHIFT and WIDTH controls for some interesting effects, and the APF if in CW mode. Before retuning, remember to press the DUAL button to turn off dual reception, and also select a wide filter. When you find another signal, reselect your narrow filter after copying the new frequency into the sub vfo. 4. Operation - Using Sub Vfo B Antenna Diversity Reception This mode offers thé potential of even greater im- provements in recéption of any mode, but requires that the optional BPF-1 be installed in the FT-1000, and that two antennas be connected. Different results can be expected depending on the differences in antenna po- larization and gain at various angles. The advantages of this mode can be particularly helpful in reducing multipath distortion, especially important for optimum AMTOR and HF packet operation, although these modes require special considerations concerning sub receiver IF bandwidth. Requirements for antenna di- versity reception are: Oconnect your second antenna (used only for recep- tion) to the BPF-1, make sure that switch S1001 is set to the E BPF position (page 9). O press the RX ANT switch on the front panel to activate sub vio reception through the BPF-1 (main vio re- ception will still use the main antenna). Other than that, set up and tuning are similar to those for Bandwidth Diversity Reception, described above, except that you needn't use different bandwidths in the two vies (although you can, and will want to tor digital modes — see box below). Remember that both vfos must be set to the same mode for CW, SSB and FM reception. At the time of this writing, the vast potential for optimizing reception of different signals using diversi- ty reception with the FT-1000 15 largely unexplored. We invite you to experiment with these modes, and we hope you will share your findings with others on the air. If you find diversity reception interesting and potential- ly helpful in your regular operations, you may wish to use the CAT System with an external computer to handle the somewhat complex control procedures. Us- ing the CAT system, dual synchronous vio tuning and activating any of the diversity reception modes (or combinations of them) can be reduced to a single key- stroke on your computer keyboard. Digital Modes on the Sub Receiver The 600-Hz IF bandwidth for the sub receiver | can only be selected in the CW mode, so to use this filter for RTTY or Packet operation, CW mode must be selected and your modem ser to decode signals within the 400 - 500 Hz CW passband. The displayed freqeuncy will be 600 Hz above the (suppressed USB) carrier frequen- cy, 50 will not correspond to the main receiver display when tuned to the same signal. page 31 4. Operation - Memory Features Memory Features Memory Channel Storage The 99 memory channels in the FT-1000 each store frequency, mode, filter selection and clarifier settings copied from the main display into the displayed mem- ory channel number when the yellow YFO-A = M button is pressed and held for 1/2-second. The data to be copied from the main display may be either in the main vfo (A), or in a memory that has been retuned. Example: to store 14.25 MHz in memory channel 10. + First tune the main vfo (A) to the desired frequency. To do this with the keypad (as just one of several ways it could be done), press ENT and then the keys with the (yellow) numbers 1 4 2 5 0 0 0, followed by the ENT key once more. Also select the desired mode and BANDWIDTH filter. + Next rotate the MEM knob until 10c# is displayed (to select the channel number to store). * Now just press and hoid the yellow VFO-A = M button for 1/2-second, until a double beep sounds from the key beeper (confirming that the memory has been stored). If you have the clarifier set for some offset, and either receive or transmit clarifier functions activated, these settings are also stored in the memory. Checking Stored Memories One memory channel number is displayed at all times (just to the left of the CH at the right center of the display). You can change the selected channel number by rotating the MEM knob at the right edge of the front panel. If you rotate this knob while receiving on a vio or a retuned memory, M CK will appear blinking above the channel number, and the mode and frequency previ- ously stored in the selected channel will be displayed in place of the sub vfo data, until a few seconds after you stop turning the knob. Try that now. You can also view memory frequencies and modes by pressing the M CK button beneath the main tuning knob, in which case memory channel data (and M CK, non-blinking) will be displayed until you press M CK again to return the display to the sub vfo. Of course, if nothing has been stored in a memory, you will not see any frequency or mode displayed — just the two deci- mal points in place of the sub vfo display. Also, after recalling a memory to the main display as described next, as long as you haven’t retuned it, you can view the other memories by turning the MEM knob. In this case, however, reception will shift to each mem- ory as it appears on the main frequency display: Memory Channel Operation/Recall To recall data stored in a memory channel for opera- tion, you can either copy it into the main vfo, or you can switch operation from the main vfo to the memories. The M = VF0-A button can be used to copy the current memory channel data into the main vfo, by pressing and holding this button for !/2-second. Pressing it only momentarily shows you the contents of the memory, without actually overwriting the vfo data. (Otherwise, when you press and hold this button, the previous contents of the vfo are lost). In most situations, however, you may find it more convenient to simply switch operation from the main vfo to the memory, by pressing the YFO/MEM button to the right of the yellow button, near the lower right. This method allows you to leave any settings in the main vfo undisturbed, so you can instantly recall them just by pressing VFO/MEM again. When actually operating on a memory channel, MEM appears at the left side of the display (instead of vFo), and you can rotate the MEM knob to select any previ- ously-stored memory for operation. If you change frequency, mode, filter or clarifier settings while operating on a memory, MEM on the dis- play is replaced with M TUNE. This makes each memory just as flexible as the main vfo. If you want to save any changes you have made to a memory channel, just rotate the MEM knob (if you want to store the new settings into another channel), and press the yellow VFO-A = M button for !/7-second until the double beep sounds (of course you needn’t turn the MEM knob if you want to overwrite the memory channel you're on now). Note that in this instance the labelling of the VF0-A = M button is somewhat deceptive: the settings of the main vfo, which are hidden at this point, are not actually involved in this operation at all, since those of the recalled memory have taken their place. If you just want to cancel any changes you have made to a recalled memory, press VFO/MEM once (MEM will be displayed again), and press it again if you want to return to the main vio (A). | Dual channel reception, split operation and all types of diversity reception can be activated while operating On a memory, in which case the recalled memory simp- ly replaces the main vfo settings. Note: There 1s a “back door” feature of memory operation that does affect the main vfo — that is sub- band selection. Memories do not actually store their own subband settings like those used by the main and sub vfos (by pressing the keypad key for the band that page 32 re E Ta T= EE VE OR SE 4. Operation - Memory Features you are already on). However, if you do this (press the key for the current band) while operating on a memory, operation will shift to the alternate subband settings for the main vo! You will be able to retune the subband settings, and change mode, filter and clarifier settings. You can even store the new settings in a memory channel, and then return to the original subband. How- ever, when you later return to vio operation (by press- ing YFO/MEM once or twice), and then recall the alternate subband, its settings will be those last set on the sub- band while operating on the memory. If vou try this, use care, as you can unwittingly erase your subband set- tings if you return from a memory to the vio while having a subband selected (in memory tune mode). Memory Scanning You can scan any stored memories by pressing the M SCAN key at the upper right corner. However, for this to work, you must first adjust the SQL control so that the recelver is silenced (green MAIN BUSY LED at the right of the meter off). During memory scanning, the scanner will pause on any channel having a signal strong enough to open the squelch, during which the two decimal points in the main frequency display will blink. Scanning resumes a few seconds later), so you may need to readjust the SQL control to keep the scanner from stopping on channels with high background noise. To stop the scanner, press the PTT switch (no trans- mission will occur), or the M SCAN button again. Note that the FRONT END and RF gain settings also affect the squelch threshold. Memory Scan Skip Once you have stored a lot of memories, you prob- ably won't want to scan every one of them. You can mark some of them to be skipped during scanning. To do this, recall the channel to be skipped, and press and hold the FAST button below the left side of the main tuning knob while also pressing M SCAN momentarily. By default, when a memory is first stored, it is set to be included in scanning (SCAN is displayed above the channel number). When you set the memory to be skipped, this indicator disappears from the display, If you have set a memory to be skipped, and later want to include it, just repeat the same FAST + M SCAN procedure. Memory Blanking After storing many memories, you may want fo completely hide some from normal operation, to simp- lity selection of the others. To blank a displayed mem- ory, while MEM is displayed at the left of the frequency, press and hold the yellow VFO-A = M button for 1/5- second until the double beep sounds (this won't work if M TUNE is displayed — if you have retuned the memory, either store It again, or cancel changes by pressing YFO/MEM once). As long as you don't overwrite a blanked memory, you can unblank it simply by repeating the same proce- dure you used to blank it. Optional DVS-2 Digital Voice Recorder The DV 5-2 is a digital recorder designed especially for the FT-1000, which has a special jack for connection of the DV5-2 on the rear panel. It offers two independent functions: recording received signals for playback later in the loudspeaker/headphone, and recording signals by the microphone for playback later over the air (during transmission). Operating details are provided with the DVS-2, but a summary is provided here. Receiver Recording When used in this mode, the DVS-2 maintains a continuous recording of the last 18 seconds of audio from the main receiver. This can be particularly helpful in picking out callsigns during a pileup, as you can replay the same recording several times. As the DVS-2 uses only the main receiver audio channel, real-time action can be continually monitored on the sub vfo audio channel while playing back on the main channel. Transmission Recording This mode allows the DVS-2 to record either two 8-second segments or four 4-second segments of audio from the microphone, such as contest exchanges or station ids. Each can then be played back, either in a monitor mode (without transmission), or directly over the air. The 8- and 4-second segments share the same memory, 50 two 4-second segments can be combined into one 8-second segment. Note that the digital memory used in this mode is independent from that used for receiver recording, page 33 BF 4 "| 4. Operation - Digital Modes: AMTOR, RTTY & Packet ER SC ON TER GETS NE AR RS Digital Modes: AMTOR, RTTY & Packet The FT-1000 offers some special features to meet the requirements of digital modes, such as a built-in digitally-synthesized AFSK generator for RTTY and AMTOR terminal units, IF bandwidth optimization and automatic display offsets, and an 18-ms transmit- to-receive turnaround time. Antenna diversity recep- tion, described on page 30, also has the potential to improve performance greatly in these modes, Howev- er, note that the sub receiver bandwidth is fixed at 2.4 kHz in the RTTY and PKT modes. RTTY and AMTOR with a Terminal Unit Connect your TU to the RTTY jack on the rear panel, as shown below. Also, set the four RTTY DIP switches in the top access panel for the Mark frequen- cy, shift amount and usual direction you wish to use (see page 10 for the switch settings). To operate, just press the RTTY mode button, once or twice to select the desired sideband for operation (which is normal will depend on your RTTY DIP switch settings — if you selected “NOR”, LSB will give normal shift). The display shows your actual Mark frequency. For optimum signal-to-noise ratio, use the 250-Hz BANDWIDTH selection for 170-Hz shift, the 500-Hz selec- tion for 450-Hz shift, or the 2.0-kHz selection for 850-Hz shift. Before transmitting the first ime, preset the RF PWR control fully counterclockwise, and set the METER selec- rei 3 RX ANT | | — ANT ; . tor to ALC. Key the transmitter (you can use the MOX button) and adjust the MIC control for mid-scale indica- tion. Now you can switch the METER selector to PO and set thé RF PWR control for the desired power output. CAUTION The FT-1000 cooling system is designed to han- dle continuous duty transmission at 100 watts output. If you need more power output for RTTY, you must limit the length of your transmissions (or use an external linear amplifier). At 200 watts output, RTTY transmissions must be limited to 3 minutes or less, with at least 3 minutes receive in | between transmissions. In any case, place your hand on the transceiver occasionally to ensure that it’s not getting too hot. The safest approach is to keep power output at 100 watts or less. 300-Baud Packet Connect your Inc to the PACKET jack on the rear panel, as shown on the next page. Do nor connect the squelch line (pin 5) for 300-baud packet operation. Tuning is very critical for F1 packet: you should tune the transmitter and receiver within 10 Hz of a signal to minimize repeats. The FT-1000 includes a packet frequency display offset feature that allows it to FT-1000 — IE L a nla == ac RI TY Machine Г” Г o FSK OUT AF IN PTT = 8. с i | RTTY/AMTOR Terminal Unit Interconnections page 34 4. Operation - Digital Modes: AMTOR, RTTY & Packet р display the center frequency of the two transmitted carriers, without any offset, in accordance with the latest convention. However, for this to work properly, you must set the PKT DIP switches in the top access panel to match the tones generated by your tnc. See the Packet DIP Settings Table on page 16. Select the 5S00-Hz BANDWIDTH filter for 300-baud packet, and press the PKT mode button on the front panel once or twice, so that the green LSB LED indi- cator lights along with the orange PKT LED. Transmitter adjustment is similar to SSB: e Preset the RF PWR control counterclockwise, and set the METER selector to ALC. | * Now set your tnc to its “calibrate” mode, preferably with both tones alternating, and adjust the MIC con- trol so that the meter deflects to mid-scale. * Switch the METER selector to PO and advance the RF PWR control for the desired power output. When tuning, bear in mind that some common hf packet channels, such as “14.103” MHz, were original- ly determined to correspond with an actual IF center frequency 1700 Hz lower (in accordance with an old TAPR convention). Therefore, if you have the DIP switches set to match your tnc”s actual tones, the dis- play will show 14.101.30 when you are tuned to the above frequency — which is the actual center of your receiver passband, and the frequency mid-way be- tween the two FSK carriers you will transmit. Initially, you may need to adjust the receiver IF shift a few clicks to the right or left to get the 500-Hz IF filters perfectly centered over incoming signals. Start 2RX ANT ANT with the SHIFT control centered, and try to establish a connection with a moderately strong signal on a clear channel. If the connection is poor (many repeats), move the SHIFT control one click to the right, and see if the repeats decline. Continue in this manner until you find a “sweet spot” (with minimal repeats) for the SHIFT control, and make note of it. You will use this same setting for all future hf packet operation. 1200-Baud FM Packet The equipment setup for 1200-baud FM packet (above 29 MHz) is the same as for 300-baud packet, except that you may want to connect the squelch line of the tnc to pin 5 of the PACKET jack if you plan to use the squelch. Press the PKT mode switch unti: both it and the green LED on the FM mode button are lit. Tuning is much less critical in this mode, requiring no special adjustments. Also, the FM MIC GAIN control in the top access panel has been preset at the factory for proper deviation with typical signal levels, so you should not need to readjust it (you should adjust the tx audio output level of your tnc, though, if your signal sounds distorted in the monitor). To set up the transmitter for FM packet: o Start with the RF PWR control counterclockwise, and set the METER selector to ALC. * Set your tnc to its “calibrate” mode, preferably with both tones alternating, and adjust the DRIVE control so that the meter deflects to mid-scale. | * Switch the METER selector to PO and set the RF PWR control for the desired power output. —FT-1000 U.” Ea — —— — = hm Packet TNC Interconnections (Cats) | TNC | Do | © DATA DATA cooo QO OO °° BUSY RX/TX OU IN e q 9 © о РАСКЕТ — + r = Tf i 1 i L 7 > В, page 35 5. CAT System Computer Control EEE. HI TEN ET RE Les RE ке Cat System Computer Control The CAT (Computer Aided Transceiver) System in the FT-1000 provides control of frequency, mode, vfo, memory and other settings by the operator's external personal computer, This allows multiple control opera- tions, such as dual-channel memories and diversity reception, to be fully automated as single keystroke operations on the computer keyboard. Serial data is passed at TTL levels (0 and +5V) via SO (serial output) and SI (serial input) pins 2 and 3 of the CAT jack on the rear panel of the transceiver at 4800 bits/s . CAT jack pinout is shown on page 7. Each byte sent consists of one start bit, 8 data bits, no parity bit and two stop bits: RECI LE All commands sent from the computer to the trans- ceiver consist of blocks of five bytes each, with up to 200 ms between each byte. The last byte sent in each block is the instruction opcode, while the first four bytes of each block are arguments: either parameters for that instruction, or dummy values (required to pad the block out to five bytes): [4 Avg Bye [aed Avg By [2d Ag Bye ist Arg By] Opcode 5-Byte Command Block (sent Left-to-Right) There are twenty-seven instruction opcodes for the FT-1000, listed in the table on the next page. Notice that several instructions require no specific parameters. However, every Command Block sent to the trans- ceiver must always consist of five bytes. The CAT control program in the computer must construct the 5-byte block, by selecting the appropriate instruction opcode, organizing the parameters, if any, and providing unused (dummy) argument bytes for padding (the dummy bytes can contain any value). The resulting five bytes are then sent, opcode last, to the SI serial input pin of the CAT jack on the transceiver. EXAMPLE: Set main vio (A) to 14,25000 MHz; OJ First determine the opcode for the desired instruc- tion (see the CAT Commands Table). These op- codes should be stored in the program, so they can be looked up when the user requests the correspond- ing command.

Update causes the transceiver to return 1,636 bytes of Status Update data, while Read Flags obtains only the first 3 bytes (the Status Flags), plus 2 extra “filler” bytes (10h and 21h), and Read Meter returns the meter deflection (0 — OFFh) repeated in four bytes, followed by one “filler” byte (OF7h). Each byte of returned data may be delayed by an interval determined by the Pa- cing command (0 to 255 ms in 1-ms steps). This delay is initially zero unl the Pacing command is sent. The Pacing command allows returned data to be read and processed by even very slow computers. However, you should set it as short as your computer will accommodate, to minimize the inconvemence of the delay. Sending 1,636 bytes requires just under 4 seconds with “0"-length delay selected, but over 7 minutes if the maximum delay 15 selected!, Status Update Data Organization The 1,636 bytes of Update data consists of 24 one- bit state indicator flags (3 bytes), followed by one byte indicating the current (or last selected) memory chan- nel, followed by 102 16-byte channel records: one for the current operating parameters, one each for vios A and B, and one for each of the 99 memories. The Read Flags data consists of just he 24 one-bit state indicator flags (3 bytes), plus 10h and 21h, as mentioned above. These data arrangements are shown pictorially on the page after next. 5.

CAT System Computer Control En TT MEER ES SSE EE A AE RE ST Ns Data Returned From F'T-1000 Update Data An overview of the data returned to the PC in response to the Update command is shown at the right. The sequence of the data stream is from top left w bottom. The first three bytes are subdivided into 1-bit flag fields: if a bit is set (1), the function is enabled (on); and if reset (0), the function is disabled (off). These flags reflect the current states of various functions, most of which are indicated on the radio display.

CAT System Computer Control Read Flags Data The Read Flags command retrieves the three Flag Bytes (and two padding bytes) without having to read the entire 1,636-byte Update Status. The transceiver responds to the Read Flags command by returning the Flag Bytes described on the preceding page, plus two additional bytes with the constant values of 10h and 21h (in that order), as shown here: Flags Byte 1 | Flags Byte 2 | Flags Byte 3 | Dummy (10h) | Dummy (21h) Read Meter Data Sending the Read Meter command causes the com- puter to return a digitized meter deflection indication, between 0 and OFFh (in practice, the highest value returned will be around OFOh). Four copies of this value are returned, along with one padding byte (OF7h), as follows: Meter Byte | Meter Byte | Meter Byte | Meter Byte OF7h During reception, the signal strength deflection is returned. During transmission, the parameter repre- sented by the reading returned depends on the setting of the METER switch. Coding Examples Although Yaesu Musen Company cannot offer to provide complete CAT control programs (owing to the large variety of incompatible computers used by our customers), following are a few examples of critical CAT i/o functions, in Basic. Note that all variations of Basic may not support some of the commands, in which case alternate algorithms may need to be devel- oped to duplicate the functions of those shown. Sending a Command After “opening” the computer’s serial port for 4800- baud, 8 data bits and 2 stop bits with no parity, as 1/0 device #2, any CAT command may be sent. However, if you determine that your computer may need extra time to process data returned from the transceiver, you should send the Pacing command first. Here is an example of the Pacing command setting a 2-ms delay: PRINT #2, CHR$(0);CHR$(0);CHRS (0) ;CHRS (2) ; CHRS (&HE) ; Notice that the instruction opcode 1s sent last, with the first (MSB) parameter sent just before it, and the LSB parameter (or dummies) sent first. This means that the parameters are sent in the reverse order from that in which they appear in the CAT Commands table. Also note that in this and the following examples, we are sending zeros as dummy bytes: this is not necessary, however. If you decide to send commands through a S-byte array, they values of the dummy parameters need not be cleared. Using the same example as on page 36, the follow- ing command could be used to set the frequency of the display to 14.25000 MHz: PRINT #2, CHR$ (&H00) ; CHR$ (8H50) ; CHR$ (&H42); CHR$ (&H01) ; CHR$ (&HA) ; Notice here that the BCD values can be sent just by preceding the decimal digits with “&H” in this ex- ample. However, in an actual program, it may be pref- erable to convert the decimal frequency variable in the program to an ASCII string, and then to convert the string to characters through a lookup table. If you send a parameter that is out of range for the intended function, or not among the specified legal values for that function, the FT-1000 should do no- thing. Therefore, you may wish to alternate your sen- ding regular commands or command groups with the Read Flags command (and occasionally even the Up- date command), allowing the transceiver to let the computer know if everything sent so far has been ac- cepted and acted upon as expected. Bear in mind that some commands specify “bi- nary”, as opposed to BCD formatted parameters. You can send binary parameters without going through the character/hex string conversion process. For example, the CH parameter in the Command table is a binary value. You could have the FT-1000 recall memory channel 50 (decimal) by the following: PRINT #2, CHR$ (0) ; CHR$ (0) ; CHR$ (0) ; CHR$ (49) ; CHR$ (2) ; Note that we have to send 49 to get channel 50, since the channel numbers in the command start from 0, while those on the display start with 1. Reading Returned Data The reading process is easily done through a loop, storing incoming data into an array, which can then be processed after the entire array has been read. To read the meter: FOR I=1 TO 5 MDATA(I) = ASC(INPUT$(1,#2)) NEXT I Recall from above that the meter data consists of four identical bytes, followed by a filler byte, so we really only need to see one byte to get all of the infor- mation this command offers. Nevertheless, we must read all five bytes (or 1,636, in the case of the Update data). After reading all of the data, we can select the bytes of interest to us from the array (MDATA, in the above example). page 39 6.
