FLARE] - 1.1 KENWOOD TS-830S The TS-830S is a highly sophisticated solid state Amateur band transceiver employing only three vacuum tubes. Operating on all Amateur bands between 1.8 and 29.7 MHz, this unit is constructed modularly. The TS-830S includes many built-in features usually found as extras on other transceivers. Included are VOX, 25 kHz calibrator, RIT, RF attenuator, and an effective noise blanker. The TS-830S also includes automatic gain control (AGC), automatic level control (ALC), semi-break-in CW with sidetone, a speech processor, speaker and built-in AC power supply. Designed for operation on SSB or CW, the TS-830S delivers more than 220 watts PEP input. Any complicated electronic device will be damaged if operated incorrectly, and this transceiver is no exception. Please read all of the operating instructions before putting your TS-830S on the air. 1.2 FEATURES 1. Interference-free DX operation * Variable bandwidth IF filter circuit (VBT) The built-in VBT (Variable Bandwidth Tuning) circuit al- lows IF filter pass-bandwidth to be varied as you wish to eliminate unpleasant interference. It is adjustable independent of the IF shift. * |F shift circuit The IF SHIFT (also called pass-band tuning) is a circuit to shift IF pass-bandwidth without changing receive frequency. It eliminates interference or adjusts receive frequency characteristic as desired. * High reliability 455 kHz notch circuit Interference, is also eliminated by the built-in notch circuit. The TS-830S uses 455 kHz notch-frequency. The notch circuit shifts the BFO frequency and the local mixer frequency at the same time, thereby equiva- lently changing the notch frequency. Thus, accurate notch characteristic is realized even when the notch point is changed, completely eliminating nearby inter- ference signals. * NARROW/WIDE BANDWIDTH selection and optional filters for enhanced CW operation: NARROW or WIDE CW operation can be selected when using the following optional filters: YK-88C (500 Hz), YK-88CN (270 Hz), YG-455C (500 Hz), YG-455CN (250 Hz) *Variable tone control circuit. 2. WARC bands The TS-830S fully covers 160-10 m Amateur bands, including the new WARC bands of 10, 18 and 24.5 MHz. The TS-830S VFO covers more than 50 kHz above and below each 500 kHz band. The optional VFO-230 external digital VFO covers about 100 kHz above and below each band, for MARS and other applications. 3. “ SECTION 1.

Choose an operating location that is dry and cool, and avoid operating the transceiver in direct sunlight. Also, allow at least 3 inches clearance between the back of the equipment to any object. This space allows an adequate air flow from the ventilating fan to keep the transceiver cool.

E GROUND To prevent electric shock, and reduce the possibility of TVI and BCI, connect the transceiver to a good earth ground. through as short and heavy a lead as possible. Use ground rods or metal cold water feedline. NOTE: A ground connection greater than 1/4 X away from the transceiver may be a good DC ground, but NOT an RF Ground. E ANTENNA Connect through a 50 ohm antenna feedline to the coaxial connector on the rear panel. @ KEY If CW operation is desired, connect a key to the KEY jack. Use shielded line or coaxial cable. Em POWER CONNECTIONS Make sure the POWER switch on the front panel is turned off, the stand-by switch is in the REC position, and the line voltage is correct. Then connect the power cord to the line source. E AC POWER For fixed station operation, the TS-830S is supplied to operate from a 120V AC. 50/60 Hz power source capable of supplying 280 watts or more. 24 MICROPHONE Attach the microphone connector to a suitable microphone, as shown in Figure 2-1. Be sure the microphone PTT switch Is separate from the microphone circuit, as shown in Figure 2-1A. It should be noted that a microphone with a 3P plug using a common ground terminal should not be used. The microphone input is designed for 500~50 kQ microphones. The choice of microphone is important for good speech quality, and should be given serious considera- tion. The crystal lattice filter in the transceiver provides all the restriction necessary on audio response, and further restriction in the microphone is not required. It is more im- portant to have a microphone with a smooth, flat response throughout the speech range. Follow the microphone manufacturer's instructions for con- necting the microphone cable to the plug. With many microphones, the push-to-talk button must be pressed to make microphone audio available. For VOX operation, this unwanted feature may be eliminated, if desired, by opening the microphone case and permanently connecting the contacts which control the microphone audio. Standard microphone sensitivity is within the range of —50 dB to —60 dB. If a microphone having a higher sensitivity is used, the ALC and compressor circuits will not function properly. In this case, insert in the mike line an attenuator as shown in Fig. 2-1C. A typical MIC gain control setting is 12 o'clock. If you must run this control at 9 o'clock or less, use an attenuator. 2.5 KEY If CW operation is desired, connect a key to the KEY jack. Use shielded cable, and a standard (mono or 2P) phone plug. Headphones Use headphones of 4 to 162 impedance. The optional HS-4, HS-5 headphone is best suited for use with the TS-830S. Stereo-type headpho- nes can also be used. Microphone Either a low or high impedance microphone (500 to 50 k®) can be used. The P.T.T. switch should be isolated from the mic circuit (shown in “A”). Use a microphone with a separate switch and MIC line so both PTT. and VOX are available. — A — + B | View from cord side Transformer o E y Microphone D e 3 Microphone (a) this ó swieeh : Transformer ит [= —! te Microphone D e | Е € Switch р | (b) not this А a | Microphone D e 3 (c) not this Antenna Key Lightning a arrestor Transformer Microphone connection EO7-0403-05 | Switch IO K ~ 33 K [esos E Microphone connector o о Microphone IO K AAA Monitor scope External speaker GND terminal It is recommended that a ground lead be connected to the GND ter- minal at the rear of the set to prevent the possibility of electric shock, TVI and BCI.

The TS-8305 has a built-in the SPEAKER plus an external speaker jack on the rear panel. The speaker may be an 8-ohm permanent-magnet type, 4 inches or larger. The internal speaker is disconnected when an external speaker is used. Headphones should also be 4 to 16 ohms im- pedance. When the headphones are connected to the front-panel PHONES jack, the speaker is disabled. 2.7 GROUND To prevent electric shock, and reduce the possibility of TVI and BCI, connect the transceiver to a good earth ground through as short and heavy a lead as possible. 2.8 ANTENNA Any of the common antenna systems designed for use on the high frequency amateur bands may be used with the TS-8305, provided the input impedance of the transmission line is not outside the capability of the pi-output matching network. The transmission line should be coaxial cable. An antenna system which shows a standing wave ratio of less than 2:1 when using 50 or 75 ohm coaxial transmission line, or a system that results in a transmission line input impedance that is essentially resistive, and between 15 and 200 ohms will take power from the transceiver with little difficulty. If openwire or balanced type transmission line is used with the antenna, a suitable antenna tuner with balun is recommended between the transceiver and the feed line. Methods of construction and operating such tuners are described in detail in the ARRL Antenna Handbook, and similar publications. For operation on the 160, 75 and 40 meter bands, a simple dipole antenna, cut to resonance in the most used portion of the bands, will perform satisfacto- rily. For operation of the transceiver on the 10, 15 and 20 meter bands, the efficiency of the station will be greatly increased if a good directional rotary antenna is used. Remember that even the most powerful transceiver is useless without a proper antenna. CAUTION: Protect your Equipment — Use a LIGHTING ARRESTOR. Mobile Station — Mobile antenna installations are critical, since any mobile antenna for use on the high frequency bands represents a number of compromises. Many amateurs lose the efficiency of their antenna through improper tuning. Remember the following points when using the TS-830S with a mobile antenna. The “QQ” of the antenna loading coil should be as high as possible. The loading coil must be capabie of handling the power of the transceiver without overheating. In the CW mode the power output of the transceiver will exceed 80 watts. The SWR bridge is a useful instrument, but unfortunately it Is quite often misunderstood, and overrated in importance. Basically, the SWR bridge will indicate how closely the antenna load impedance matches the transmission line. With long transmission lines, such as will be used in many fixed station installations, it is desirable to keep the impedance match fairly close in order to limit power loss. This 1s particularly true at the higher frequencies. The longer the line, and the higher the frequency, the more important SWR becomes. However, in mobile installations the transmission line seldom exceeds 20 feet in length, and an SWR of even 4 to 1 adds very little power loss. The only time SWR will indicate a low figur2 is when the antenna presents a load close to 50 ohms, but many mobile antennas will have a base impedance as low as 15 or 20 ohms at their resonant frequency. In such cases, SWR will indicate 3 or 4 to 1. and yet the system will be radiating efficiently. The really important factor in your mobile antenna is that it should be carefully tuned to resonance at the desired frequency. The fallacy in using an SWR bridge lies in the fact that it is sometimes possible to reduce the SWR reading by detuning the antenna. Field strength may actually be reduced in an effort to bring SWR down. Since field strength is the primary goal, we recommend a field strength meter for antenna tuning. For antenna adjustments, the transceiver may be loaded lightly, using the TUNE position instead of operating at full power output. This will limit tube dissipation during adjustments, and will also help to reduce interference on the frequency, In any case, do not leave the transmitter on for very long at one time. Turn it on just long enough to tune and load, and get a field strength reading. Start out with the antenna whip at about the center of its adjustment range. Set the VFO to the desired operating frequency and then adjust the PLATE control for a dip, and then the LOAD control. Then observe the field strength reading. The field strength meter may be set on top of the dash, on the hood, or at an elevated location some distance from the car. Change the whip length a half inch or so at a time, retune the finals each time, and again check the field strength at the antenna. Continue this procedure until the point of maximum field strength is found. This adjustment will be most critical on 75 meters, somewhat less critical on 40, until on 10 meters the adjustment will be quite broad. After tuning the antenna to resonance, the finals can be loaded to full power. “SECTION 3.

VFO INDICATOR LED The VFO indicator illuminates when the internal VFO controls transceiver operation. The indicator is not lighted during fixed channel or remote VFO operation. 3. FIX (FIXED CHANNEL) INDICATOR LED The FIX indicator illuminates when the internal fixed frequency oscillator controls transceiver operation. 4. RF ATT INDICATOR LED ® This illuminates when the RF ATTENUATOR is turned ON. 5. DH (DISPLAY HOLD) SWITCH With this switch ON, the display frequency remains ON even if the main tuning is changed. This feature is used to memo- rize the original frequency when checking another frequency. 6. METER The meter monitors six different functions, depending on METER switch position. In receive the meter is automatically an S-meter, and shows received signal strength on a scale of O to 40 dB over S9. In transmit, meter function depends on the position of the METER switch, as described below. This is an average-responding meter, NOT peak-reading. 7. PROC (SPEECH PROCESSOR) SWITCH 7) This switch is used during SSB operation. Set the switch to the ON position and the speech processor will be activated, increasing the average talk power. Compression level can be adjusted by the processor control (8). 8. COMP LEVEL CONTROL @ This control adjusts compression level. Set the meter switch (12) to the COMP position and adjust this control while observing the meter COMP scale. 9. NB SWITCH 6) With the push switch, the noise blanker circuit is turned ON reducing pulse-type (ignition) noise. Power-line, radar, QRM and atmospheric “white” noises will not operate the blanker. The noise blanker circuit operating level is adjustable by the noise blanker control (10). 10. NB LEVEL CONTROL ® This control adjusts the noise blanker circuit operating level according to receiving conditions or noise level. 11. AGC SWITCH ® This controls the AGC (Automatic Gain Control) circuit: OFF.............. AGC disabled (no AGC). FAST... Normally used for CW operation. SO Vera Normally used for SSB operation. 12. METER SWITCH This determines the transmit meter function: ALC (Automatic Level Control) Monitors internal ALC voltage, or the ALC voltage feedback from a linear amplifier operated in conjunction with the TS-830S. For SSB operation the ALC reading for voice peaks should be within the indicated ALC range. ALC voltage adjustment is made with the MIC control for SSB and with the CAR control for CW. IP (Plate Current) In this position the meter monitors final tube plate cur- rent. The scale is calibrated from O to 350 ma. RF (Output Power) This monitors relative output power of the transceiver. There is no meter scale for this position. Normally the reading should be adjusted (with the RF METER control) for a 2/3 scale reading. COMP This indicates compression level when the speech processor is operating. HV (High Voltage) This position monitors the high voltage power supply. The meter scale is calibrated from O to 10, indicating O to 1000 volts. 13. STAND-BY SWITCH M This two-position lever switch selects: REG cou The transceiver is receiving unless the microphone PTT switch, or the VOX circuit is activated. SEND even Locks the unit in transmit. 14. VOX GAIN M This controls sensitivity of the VOX (Voice Operated Transmit) circuit. 15. VOX DELAY CONTROL M The DELAY control adjusts the hold time for VOX or break-in CW operation. Adjust for individual preference. 16. PHONES JACK ® The headphones jack allows use of a 4 to 16 ohm headphone through a 1/4” phone plug. When phones are used the speaker is disconnected. 17. MIC CONNECTOR 7 The four pin connector allows use of a microphone with PTT. Figure 2-1 shows plug wiring. 18. MODE SWITCH The mode switch selects type of emission, and TUNE. TUNE ........... This position provides reduced carrier and shorted key line for transceiver tuning. (Input power to the final section is reduced to prevent tube damage during tune-up.) Frequency is shifted approximately +800Hz from the USB or CW receive frequency. This is the actual CW transmit offset. This feature allows you to Zero-Beat an incoming CW signal. CV Vi casas Used for CW operation. A high-cut filter is inserted in the receiver audio circuit to reduce unwanted noise. SSB filter selected for WIDE receive bandwidth. CWN (NARROW) Used for CW operation with CW filters YK-88C (500 Hz), YK-88CN (270 Hz), YG-455C (500 Hz) or YG-455CN (250 Hz), which are available as optional accessories. Without an optional CW filter installed, the pass-bandwidth is the same as in CW.W, USB............ Used for upper-sideband operation. Inter- national Amateur practice dictates the use of USB on and above the 10 MHz band. LEB seves Selects lower-sideband. International Amateur practice dicates the use of LSB on and below the 7 MHz band. 10 19. MIC GAIN CONTROL M This control adjusts microphone amplifier gain for SSB operation. Adjust for an on-scale ALC reading on voice peaks. In the CAL ON position, receive frequency can be calibrated at 25 kHz intervals using the built-in oscillator. 20. CAR LEVEL CONTROL ©) This controls carrier level during CW operation. Adjust for approximately 250 mA of plate current. 21. FIX SWITCH Place this switch ON for fixed channel operation: (an optional crystal is required. Trio-Kenwood does not supply these crystals.) 22. MONI (MONITOR) SWITCH © This delivers a sample of the demodulated transmit IF signal to the AF for monitoring modulation. 23. RF ATT SWITCH ® With this switch ON, A 20 dB attenuator is inserted in the antenna circuit, protecting the RF amplifier and mixer from overload on strong input signals. 24. DIGITAL DISPLAY The digital display indicates operating frequency to the nearest 100 Hz. 25. ANALOG DIAL SCALE The mono-scale permits direct analog frequency readout over the O to 500 kHz range, graduated at 1-kHz intervals. Operating frequency equals the dial (in kHz) plus the BAND switch frequency (in MHz). An additional 50 kHz both above and below the 500 kHz range is also covered. 26. MAIN TUNING This controls the VFO, selecting the transceivers operating frequency. The indented knob is convenient for quick tu- ning. 27. LOAD CONTROL (7 This controls the loading of the network between the final section and the antenna. Adjustment is described in Section 4. 28. PLATE CONTROL M This controls the plate tuning of the final amplifiers. Ca- libration is approximate, 29. DRIVE CONTROL This control tunes the plate tank circuit of the 12B Y 7A driver as well as the receiver's antenna and mixer coils. In receive the DRIVE control is tuned for maximum sensitivity (maximum S-meter deflection), and in transmit for a maximum on-scale ALC reading. These points occur concurrently. Tuning for one also achieves the other. 30. RIT/XIT INDICATOR LED This indicator will light when the RIT switch (44) or XIT switch (43) is ON. 31. RIT/XIT CONTROL This control allows the receive frequency, transmit frequency or both to be shifted without using the main tuning control. With the RIT switch (44) ON, the RIT circuit is activated to shift only the receive frequency. With the XIT switch (43) ON, the XIT circuit is activated to shift only the transmit frequency. When both switches are ON, both frequencies are shifted. The center (0) position equals no shift. 32. BAND SWITCH The 10-position switch selects all Amateur bands from 1.8 to 29.7 MHz. To select the 28.5 or 29.5 MHz bands, push the +0.5 switch (33) ON. Use the 10 MHz band for WWV reception. An AUX receive band is also available. Coilpack (Receiver front-end) and PLL components must be installed and aligned for the specific receive frequency range desired. 33. +0.5 SWITCH This switch is used in conjunction with the bandswitch (32.). Depress the switch with the bandswitch set to 28”, and the transceiver will operate in the 28.5 MHz band. When the bandswitch is set to “29”, the transceiver will operate in the 29.5 MHz band. This switch has no function at any other bandswitch position. 34. RF GAIN ® This adjusts receiver RF amplifier gain. Turn fully clockwise for maximum gain and a correct S-meter reading. 35. AF GAIN ® This adjusts receiver audio level. clockwise. Volume increases 36. POWER SWITCH This switches all power to the transceiver. 37.

E MB LEVEL Coma LEVEL — O —— METER о GAIN DELAY oN Coen cr "a REC o Drive Control Fig. 4-2 (Preselector) Adjustment (1) Basic Procedures for Receive Operation The TS-830S has many advanced features such as VBT, IF SHIFT, NOTCH, etc. to assure enhanced receive operation. For the use of these specialized controls and switches, refer to Section 4.2 “Reception (11)”. 14 With a suitable antenna and microphone or key connected to the transceiver, set the controls as described in Fig. 4-1. Turn the POWER switch ON. The meter, dial scale, and VFO indicator will light, indicating the transceiver is operating. Advance the AF GAIN control clockwise until some receiver noise is heard in the speaker. Turn the main tuning dial within the frequency range of the Amateur band chosen until a signal is heard. Tune the signal for clearest reception, and then adjust the DRIVE control for maximum S-meter deflection. (Fig. 4-2). (2) WWV Reception Set the band switch to “10” and turn the main tuning control to 10.0 MHz. 4.2 RECEPTION (11) This section covers operation of controls and switches to provide maximum performance from the TS-830S. (1) RF ATT SWITCH The input to the receive RF amplifier is attenuated approximately 20 dB, providing distortion-free reception. This feature may be used in cases of receiver overload, caused either by a strong local signal, or during weak signal reception when a strong adjacent signal may blank the receiver or “Pump” the noise blankes. (2) RF GAIN CONTROL RF GAIN is controlled by changing the AGC threshold voltage. Adjust the RF GAIN so the S-meter does not deflect excessively. This also reduces noise during reception. For normal operation, this control should be turn- ed fully clockwise for maximum sensitivity. Maximum "S” meter reading of an incoming signal АР ar GAINTŸ— GAIN 6 Po | !

AF RF GAIN 7Ÿ GAIN = 6 | 6 +20 añ i a EN в № in à tv HED rE ' | Turn 10 К counter a lockwis Fig. 4-3 RF GAIN Control Operation conjunction with the IF SHIFT and NOTCH filter to obtain optimum results, By setting the VBT control to the NORMAL position, maximum passband-width is obtained. The IF filter passband-width is narrowed as the control is adjusted counterclockwise, while center frequency remains unchanged. Fig. 4-4 illustrates operation. The range of variability depends on the type of optional filter used. (i) When the filter bandwidth is 2.4 kHz (without an option- al filter), the passband-width varies within the range of 500 Hz to 2.4 kHz. See Fig. 4-4A. (ii) With an optional YK-88C filter (8.83 MHz, 500 Hz bandwidth) or YG-455C filter (455 kHz, 500 Hz bandwidth), the passband-width varies from 500 Hz to approximatly 150 Hz. Since an optional filter center frequency is 700 Hz higher than that of the built-in 2.4 kHz filter, the CW receive tone will be about 800 Hz without using the IF shift. Fig. 4-4A shows the VBT function with an optional filter. (3) AGC (AUTOMATIC GAIN CONTROL) Set the AGC switch to the appropriate position: Generally for SSB, SLOW, for CW FAST, and for very weak signals, the AGC may be turned OFF. Simultaneous Use of the RF GAIN CONTROL and AGC Switch If a strong signal (such as a local station) appears in the vici- nity of the intended receive signal, the S meter may show unusual deflection due to the AGC voltage developed from the strong disturbing signal. If this occurs, turn the RF GAIN down so the meter pointer remains at about the original deflection peak and turn the AGC switch OFF. This will eliminate the unwanted AGC voltage and permit clear reception. (4) RIT/XIT First set the RIT/XIT control to center, and turn the RIT switch ON. The RIT/XIT control allows shifting the receive frequency by approximately +2 kHz without changing the transmit frequency. With the RIT switch ON, the receive frequency can be adjusted by using the RIT control. With both the RIT and XIT switches ON, both the transmit and receive frequencies can be shifted. For XIT switch operation, refer to Section 4.4 “Transmission (11) NOTE: When the RIT is ON, transmit frequency is different from the receive frequency. For normal operation, leave the RIT switch OFF. It should be turned ON only when needed. (5) VBT CONTROL (Variable Bandwidth Tuning) This control is used to eliminate radio interference by changing the IF passband-width.

This is achieved by use of a PLL (Phase-Locked Loop) in the L.O. (local oscillator) circuit. This is a major feature of the TS-830S and can be used in the following cases: 1. Adjustment of tone quality and interference rejection during SSB Reception. When the transceiver is on 20 meters and above, USB mode, turn the IF SHIFT in the “+” direction and the lower frequencies are attenuated. Turning the knob in the "—”’’ direction cuts the higher frequencies. (These procedures are reversed for LSB operation below 20 meters). Adjust the control to your listening preference. The IF SHIFT is also effective in eliminating interference from adjacent receive signals. 2. Adjustment of tone quality during CW operation. For a detailed description, refer to Section 4.4.

A beat of approximately 1.5 kHz can be eliminated at the center position of the control. In USB or CW mode, a beat signal lower than 1.5 kHz can be eliminated by turning the control clockwise.

Adjusting the NB LEVEL control varies the blanker's threshold, eliminating even low level noises. NOTE: If high level signal or noise is present on an adjacent frequency, do not use excessive NB threshold LEVEL as it may distort the received signal. If you are operating near other strong signals, use the RF ATT along with the noise blanker level control.

NOTE: The TUNE position permits tuning of the final tank circuit at reduced power without danger to the tubes. In the TUNE position, the screen voltage to the finals is reduced approximately 50% and the keying circuit is closed. Adjust DRIVE control for maximum on-scale meter deflection.

If necessary, adjust the RF METER control on the rear pa- nel to bring the output reading to about 2/3 scale. This is a meter adjustment, not an output adjustment. NOTE: Dip point may not always coincide with maximum output, because neutralization is accomplished on the 10 meter band. For this reason, you may simply adjust both the PLATE and the LOAD controls for maximum output as described in both tune-up procedure and summary Table 4-1. Table 4-1.

MODE by Band E PTT (Push to talk) OPERATION By using a microphone equipped with a PTT switch, the transceiver is ready for PTT operation. To key, depress the PTT switch with the stand-by switch left in the REC position. 44 TRANSMISSION (Il) To obtain maximum transmitter performance from your TS-830S you should understand the proper operation of the following controls and switches. (1) SPEECH PROCESSOR In SSB operation (particularly DX operation), it may be desir- able to increase “talk-power” by using the speech processor. This may make the difference between a margi- nal, and a copiable signal. Operation The speech processor system in the TS-830S is anRFclipper using two filters, one in the VBT circuit and the other in the IF. Turn the PROCESS switch ON and place the METER switch to COMP. Adjust the COMP LEVEL control while speaking into the microphone in a NORMAL tone of voice for a peak COMP scale reading of about 10-20 dB. Do not overdrive the COMPRESSOR: This will deteriorate voice quality, increase transmitter noise level, and in general make copying your signal more difficult. Next, set the METER switch to ALC and adjust the MIC control while speaking into the microphone. Ensure that meter deflection is within the ALC zone. NOTE: When a high-output microphone is used, input overload and distortion will result. To prevent this, use an attenuator in the microphone circuit as shown below, or connect a 10 — 33 kf) resistor (depending on microphone used) across the microphone input. (“Normal” mic control setting should be approximately 12 O'clock). 10k — 33 k (depending on microphone used.) WW о from microphone = to the MIC connecter 10k £2 O— - —0 The MC-50 microphone is recommended (Microphone sensitivity: — 55 +3 dB for approx. 5 cm distance to the mic.) (2) VOX (Voice Operated Transmit) OPERATION Adjust the transceiver as described in the previous pa- ragraph. Flip the VOX switch on and while speaking into the microphone, increase the VOX GAIN control until the VOX relay just operates. For VOX operation it is sometimes desireable to close-talk the microphone to prevent background noises from tripping the transmitter. Check that the ALC reading for voice peaks is still within range on the meter. If necessary, adjust the MIC control for proper ALC reading. If the VOX circuit is activated by speaker output, adjust the ANTI-VOX control (on the rear panel) as necessary for proper VOX operation. Do not use excessive VOX or ANTI VOX gain more than necessary to control VOX operation. If the VOX circuit transfers between words, or holds too long, adjust the release time constant by the DELAY control. 19 (3) XIT By using XIT, transmit frequency can be shifted independent of receive frequency. With the XIT switch ON, the XIT is controlled by the RIT/XIT knob and transmit frequency can be shifted by about +2 kHz. When both the RIT and XIT switches are ON, both receive and transmit are shifted without adjusting the main tuning. (4) MONITOR To monitor transmitted SSB signal quality, turn the MONITOR switch ON to sample and demodulate a part of the transmit IF signal. This feature is useful for checking modulation. or when adjusting the speech processor. When monitoring, use a headphone to avoid audio feedback. NOTE: - If the HEATER switch is OFF or the DRIVE control is in- correctly adjusted, the ALC circuit will not operate properly, causing excessively high transmit IF signal level, resulting in a distorted monitor signal. (5) CW OPERATION (fig. 4-13) Tune and load the TS-830S as described in Sections 4.3. Using shielded line, connect a key to the rear panel KEY jack, set the MODE switch to CW. and set the stand-by switch to SEND for transmitting. CW transmission is automatically monitored through the transceiver's speaker. Sidetone audio gain can be adjusted through the opening in the bottom cover. Real transmit-receive frequency (Displayed in transmission) Displayed receive frequency J y i | I 1 _ - Beat frequency 800 Hz Fig. 4-13 CW ZERO-Beat (i) Reception The TS-830S operates in two different CW modes; WIDE and NARROW. In the WIDE mode, the SSB filter (pass bandwidth 2.4 kHz, — 6 dB) and an audio filter are used. 20 In the NARROW mode, option CW filters (YK-88C, YK-88CN. YG-455C, YG-455CN) may be used to nar- row the IF pass bandwidth to 500 Hz (—6 dB) or 250 Hz along with the audio filter. In both modes, high frequencies are cut so the received signal will be more easily copied. E OPERATION WITHOUT CW FILTERS To receive CW, set the IF SHIFT control to its center position and the RIT switch to OFF. Adjust the main tuning for about an 800 Hz beat and your transmit frequency will be tuned (zeroed) to the transmit frequency of the station you are receiving. If the O beat cannot be obtained easily, adjust the IF shift knob, then return the mode switch to CW. The transmit frequency of the unit is adjusted to that of the mate station. You may now adjust the RIT for a pitch which suits your preference. If interference is encountered, adjust the IF SHIFT. For more convenient and effective CW operation, use of the optional CW filters is recommended. ® OPERATION WITH CW FILTERS (OPTION) Set the IF SHIFT to its center position and the RIT OFF. Adjust the main tuning for maximum S-meter deflection. Receive signal pitch will be about 800 Hz, indicating correct tuning. Em KEY CONNECTION (Fig. 4.14) Your key should be connected as illustrated in Fig. 4-14. When using an electronic keyer, make sure that polarity is correct. Use shielded line from the key to transceiver. NOTE: When using an electronic keyer, set polarity of the keyer for NEGATIVE keying. ANTI VOX EXT SP GND O © IF OUT Before connecting. check that polarity is correct. The KEY jack provides — 65V. 1 2 Fig. 4-14 Key Connection E SEMI-BREAK-IN OPERATION The TS-830S has a built-in side-tone oscillator to permit semi-break-in operation, besides the normal CW operation. During semi-break-in operation, the transceiver is set in transmit mode when the key is depressed, and returns to receive mode when the key is released. For semi-break-in operation, place the STANDBY switch to REC and turn the VOX GAIN control ON. Adjust the DELAY control for your preference. 4.5 FIXED CHANNEL OPERATION A fixed channel is available for common use on all bands by installing a crystal in the socket on the PLL unit (X50-1680-00). The crystal frequency can be computed by the following formula: Crystal Frequency (MHz) = 55 MHz — X + Operating Frequency (MHz). X = Band Switch frequency (1.5, 3.5, etc.) Crystal specifications: See Fig. 4-15 NOTE: TRIO-KENWOOD does not supply crystals. The shift stet circuit CW frequency between transmit and receive, and the RIT/XIT circuit are not effective in FIXED (CHANNEL OPERATION. To use the fixed frequency oscillator, depress the FIX push switch. 4.6 DIGITAL DISPLAY CALIBRATION Connect the antenna and set the BAND switch to WWV. Turn the main tuning dial to receive 10 MHz WWV. Adjust the dial until a low-frequency beat is heard. Next, turn the MIC control to the CAL position and a marker signal will be superimposed on the WWYV signal. A double beat (two beat signals of high and low frequencies) will now be heard. Adjust the IF shift for low AF response. While receiving this double beat, adjust the Standard oscil- lator trimmer through the reference frequency adjustment access opening (on the bottom of the TS-830S) so the two beats are heard as a single beat. Repeat this procedure 2 or 3 times. This completes calibration of the Digital Display. After calibration turn of the CAL switch.

Use shielded line for both ALC and RL (control line). E SSTV OR AFSK OPERATION The TS-830S will adapt very well to slow scan television or AFSK RTTY operation. For SSTV, the only cabling required are connections between the MIC connector of the TS-830S and the camera output, and between the SPEAKER jack and the monitor input. When transmitting, adjust the transmitter output so that fi- nal input power is less than 100W (less than 125 mA Ip), ог for approximately 1/2 of normal output power. for AFSK, connect the T.U. output to the MIC input. and speaker output to the T.U. input. E PHONE PATCH OPERATION The PC-1 Phone Patch can be used with the TS-830S. Recommended settings are: PC-1 RX Gain 4 TX Gain 4 Null as necessary TS-830S Vox Gain 1 AF Gain 4 Mic Gain 5 Anti Vox Max Most other phone patches will work satisfactorily without any modification to the radio. requiring only an external speaker connection, and that the Mic line be run through the patch. For those operators who desire a Patch input similar to the TS-520S or TS-820S, an input connection and terminal must be added at the Mic input preamp circuit. Use a 100 k{ resistor in series, with a 10 k2 to ground on the input side of the 100 k(2 resistor. Use shielded line, and connect as follows: On the IF unit X48-1290-00 install the fixed divider at the junction of R111 10 k{2, C103, 100 pF and C104 1 uF (input of Q19).

EXERCISE EXTREME CAUTION TO AVOID ELECTRIC SHOCK. 6.1 GENERAL Your TS-830S has been factory aligned and tested to specification before shipment. Under normal circumstances the transceiver will operate in accordance with these operating instructions. All adjustable trimmers and coils in your transceiver were preset at the factory and should only be readjusted by a qualified technician with proper test equipment. Attempting service or alignment without factory author- ization can void the transceivers warranty. E CLEANING The knobs, front panel and cabinet of the TS-830S are likely to become soiled after extended use. The knobs should be removed from the transceiver and cleaned with a neutral soap and warm water. Use a neutral soap (not harsh chemicals) and a damp cloth to clean the cabinet and front panel. B® FUSE REPLACEMENT : When the fuse blows, there is some cause. Be sure to find the cause before attempting operation. Use a 6 amp fuse for 120V AC operation. Under no circumstances use a higher amperage fuse than specified. This can cause extensive damage. Also, the warranty will be void if an oversized fuse is used. ® FAN MOTOR LUBRICATION Every 6 months dust out the final compartment, and apply a few drops of light machine oil to the front and rear fan motor bearings. WARNING: Be certain to disconnect power, and to discharge high voltage before servicing in the final compartment. 6.2 SERVICE POSITION The TS-830S should be placed on its side, with the final section up, for any alignment or service. This position permits adequate ventilation for the final tubes as well as easy accessibility to the modules. Most of the described adjustments can be made without removing the boards from the transceiver. Cl li rd ee db lel i Lite lala bo iain pai a EEE FAN NEE EN SECTION 6.

If the frequency is not the same, adjust the RIT zero preset control, VR2. To zero the RIT, turn on the calibrator and tune the VFO for about a 1000 Hz calibrator tone. Turn the RIT control to zero. Turn the RIT switch ON and adjust VR2 for the same 1000 Hz tone. Push the RIT switch ON and OFF to be sure the tones are identical. ® NOTCH ADJUSTMENT (IF UNIT) Turn the NOTCH switch OFF and center the NOTCH control. trol. Receive a 25 kHz marker signal at 1.9 MHz with a 1.5 kHz beat frequency. Turn the NOTCH switch ON. While monitoring AF output through the speaker, adjust L10 and VR1 alternately to minimize this signal. = ede] El] | (on) ee ED! me I 1 | TTT | MIX coil BEER ! | q eee L------ = | АВВ | [ore j- Oak вв | CIE E9 Eo Fig. 6-1 Coil Pack Locations < $ FRONT Panel BAND Switch adjustment Frequency 1.5 1.9 MHz 3.5 3.75 7 7.15 10 10.125 14 14.175 18 18.125 21 21.225 24.5 24.95 28.5 28 8 Table 6-1 Coil pack Alignment order 27 EH ADJUSTMENT OF ANT AND MIX COILS (COIL PACK UNIT) The ANT and MIX coils are included in the coil pack unit. Use the 25 kHz calibrator as a signal. Connect a 50{ dummy load to terminate the receiver input. Set the DRIVE control to 12 o'clock. Adjust the ANT and MIX coils for maximum S meter deflection, following the frequency table. Start with the 1.8 MHz band and then proceed to the other bands. To adjust the 10m band, use only 28.8 MHz in the 28.5 MHz band. EH ADJUSTMENT OF RECEIVE IF COILS (RF AND IF UNITS) Receive a marker signal using any frequency. Adjust the DRIVE and the main tuning for maximum S meter deflec- tion. Adjust T2 on the RF unit and L5, L6, L7, L11 and L12 on the IF unit for maximum S meter indication. DO NOT adjust L3, L4 and L9. mS METER ADJUSTMENT (IF UNIT) Disconnect the antenna with the transceiver in receive mode. Zero-point adjustment: Adjust VR2 for meter pointer zero indication. If a standard signal generator (SSG) is available, adjust VR3 so the S-meter indicates 'S-9”, at 14.175 MHz for A 40 dB (50 uV) signal. 6.4 TRANSMITTER ADJUSTMENTS EH TRANSMITTER NEUTRALIZATION (See Internal View Bottom) The TS-830S requires neutralization every time the final tubes are changed. Tune up the TS-830S into a 50 ohm dummy load at 28.5 MHz for CW operation as described in Section 4 . Set the SG switch to OFF and place a sensitive RF milli-voltmeter across the dummy load. Flip the stand-by switch to SEND and adjust TC1 (at the bottom of the final section) for a minimum reading on the voltmeter. After the final section is neutralized. flip the stand-by switch to REC and slide the SG switch ON. A receiver tuned to 28.5 MHz works very well for neutraliz- ing if an RF voltmeter is not available. Instead of tuning for a minimum voltage, tune for a minimum S-meter reading. NOTE: Since the drive tube operates into a fixed load (the finals) it is not always necessary to replace this tube when replacing the finals. CAUTION: Neutralization of the final section should be carried out with the chassis shield in place. Dangerous high voltages are present in the final section when the transceiver is turned on. Use an insulated tool to make this adjustment. 28 EH TRANSMIT DRIVE COIL ADJUSTMENT (RF UNIT) The drive coils are part of the coil pack unit. Set the SG switch on the rear panel to OFF and center the DRIVE con- trol (12 o'clock). Set the METER switch to ALC and the MODE switch to CW.W, CW.N or TUN. With the standby switch in the SEND position, adjust the drive coils for maximum ALC deflection for each band using the same frequency and in the same order as for adjustment of the ANT and MIX coils. During adjustment, adjust the CAR control so there is just enough injection to swing the ALC meter. ® TRANSMIT IF COIL ADJUSTMENT (IF AND RF UNITS) Using any frequency, place the transceiver in transmit mode in the CW.N, CW.W or TUN position. Adjust L28, 29 on the IF unit and T4 on the RF unit for maximum ALC deflection. B® CARRIER BALANCE ADJUSTMENT (IF UNIT) With a 5092 dummy load connected to the ANT terminal, adjust for maximum output at 14.175 MHz. Reduce mic gain to zero. Set the transceiver in LSB mode and adjust the RF METER control on the rear panel for maximum sensitivi- ty. The RF meter will deflect if the carrier is unbalanced. To balance the carrier, alternately adjust trimmer TC2 and trim- pot VR4 until the meter indicates minimum. Switch to USB mode and if the pointer deflects, read just so the pointer deflects equally for both LSB and USB. ® ADJUSTMENT OF SIDE TONE LEVEL (AF-AVR UNIT) Adjust VR1 to your preference. Em ADJUSTMENT OF MONITOR LEVEL (IF UNIT) Adjust VR8 to your preference. 6.5 TRANSMITTING ON WARC BANDS As supplied, the TS-830S will receive but not transmit on the 3 new WARC bands. If transmit capability is desired, a minor wiring change is required. 1. For all 3 bands: Break the line between the RF unit X44-1360-00, connector #6, Pin #1 (TOF terminal) and AF unit X49-1140-00, connector #6, Pin #4 (TOF ter- minal). 2. Or, for individual Bands: On the RF unit X44-1360-00: Band Remove (or Cut) Part 10 MHz D4 18 MHz D5 24.5 MHz D6 6.6 ANALOG DIAL ADJUSTMENT 1. Turn the main dial fully CCW. The red cursor should line up with the VFO start mark on the sub-dial. If it does not, remove the main knob (2mm allen), loosen and line the 12mm nut up the scale start point to the red cursor. 2. Turn the main knob to 50 kHz analog. Adjust the aluminum slip sub-dial to line up with any one of the larger black dial marks. 3. Note the digital error. If it is MORE than 2 kHz adjust the VFO trimmer cap TC1 (Front under the seal tape) to exactly 50.0 on the digital readout. 4. Turn the main knob to 450 analog. If the digital error is less than 2 kHz it is in spec. If the digital error is greater, proceed: For instance if the digital error is 14.454.0 (plus 4 kHz), multiply the error times 4 (16 kHz) and adjust the VFO timmer cap to the desired frequency (14.450.0) LESS the error, or 14.434.0. Next adjust the VFO inductor L3 (Center under the seal tape) back up to the desired frequency of 14.450.0. 5. If the error in step 4 was in the minus direction, reverse the direction of the correction adjustment in step 4. 6. VFO linearity final check: The digital readout and analog dial should agree to within £2 kHz at every 100 kHz dial point. 6.7 OPERATION ON 220 OR 240V AC To operate the TS-830S on 240V AC, the power transformer split primaries must be rewired from parallel to series connection. 1. Unplug the AC power cable. 2. Remove the bottom cover. 3. Remove the jumper wires between the two O terminals and two 120 terminals on the bottom of the power transformer. 4. Connect the adjacent 120 and OQ terminals at the middle of the transformer. This will provide 240V AC operation. For 220V AC operation, connect the adjacent 120 and O terminals, and move the white lead and Bypass, capacitors from the 120 terminal to the 100 terminal. 5. Change the AC fuse from 6A to 4A. Tag the power cord at the back of the radio to indicate that the transformer Is strapped for 240V AC, and the power fuse should be 4A, and not BA. 6. Replace the bottom cover and reconnect power to verify your work. 1204 240V 220V Tn, a Su FAN MOTOR CIDO Y) WHITE To POWER SW. 6.8 ORDERING SPARE PARTS When ordering replacement or spare parts for your equip- ment, be sure to specify the following information: Model and serial number of the equipment.
