MICROPROCESSOR CONTROLLED
0.7 METER ALL—MODE TRANSCEIVER
Nc ®
GENERAL DESCRIPTION
The FT-780R is a revolutionary, high performance USB, LSB, FM, and CW transceiver for
the most demanding 70 cm operator. Controlled by a NMOS 4-bit microprocessor, the
FT-780R features full PLL synthesis in 10 Hz, 100 Hz, 1 kHz, 25 kHz (US model), and
100 KHz steps. The extremely compact size of the FT-780R makes this model particularly
well suited for mobile use.
The microprocessor chip allows never-before-possible operating flexibility. As many as
four memory channels may be programmed to your favorite frequencies, and by switching
to the MEMORY SCAN position, all four memory channels will be scanned.
Digital display of the operating frequency is provided. The front panel meter consists of a
string of bright LED's, for easy monitoring of the received signal strength and transmitter
output.
The standard microphone features a PTT switch and up/down scanning controls, plus
a tone call button for repeatrer operation.
Among the convenience features of your FT-780R are receiver offset tuning for CW and
SSB, and a digitally synthesized dual VFO system. For satellite work, the transmit fre-
quency may be varied to counter Doppler shift.
We recommend that you read this manual in its entirety, so as to derive maximum benefit
irom your new FT-780R, an exciting breakthrough from the communications experts
. Yaesu.

The FT-780R has been designed for ease of opera-
tion. However, the operator may not be familiar
with some controls since the FI-780R utilizes
modern computer technology. Be sure you thor-
oughly understand the function of each control
and indicator before operating this equipment.
(1) SQL
The -squelch control quiets the receiver in the
absence of a signal on FM, It should be set to the
point where the background noise just disappears,
in order to provide maximum sensitivity.
(2) VOL
This control is the main ON/OFF switch for the
transceiver, and it also sets the audio output level
to the speaker. Clockwise rotation increases the
audio output level.
(3) STEP
The 3 positions of this switch control the tuning
rate of the main dial, as shown in Table 1.

(4) MEMORY
This switch selects the MS mode (Memory Scan}
or one of the four frequencies that the operator
has programmed into memory. Memory scan
control is exercised via the UP/DOWN switches on
the microphone.
(5) MAIN TUNING KNOB
The tuning knob is used to control the receive and
transmit frequencies over the entire 0.7 meter
amateur band. It is activated when the DIL button
is pushed.
When the transceiver is initially turned on, the
display will indicate *435.000.0 MHz, and the dial
may be turned from that point to the desired
operating frequency.
(6) MODE
This switch selects the mode of operation: USB
(upper sideband), LSB (lower sideband), CW (code
operation), and FM (frequency modulation).
Selection of simplex or +5 MHz repeater shift 15
also provided on this switch.
(7) MIC
The MIC jack is used for microphone input, PTT
control, and scanner control lines.
(8) S/PO
A string of LEDs provides indication of signal
strength and relative power output.

When this switch is pushed, the PTT line will close,
and a 1750 Hz or 1800 Hz tone will be transmitted
for accessing repeaters.
(15) CLAR
The clarifier switch allows +10 kHz offset of the
receive frequency from the dial or memory fre-
quency. Clarifier tuning is accomplished via the
main tuning dial. When the CLAR switch is
pushed, the scanning step selector should be set to
10 Hz or 100 Hz; if not, control will be returned
to the main dial, with the clarifier being disabled.
(16) M (Memory)
This switch is used for programming a frequency
into memory.
(17) VFO A/B TXA
This switch, when pressed, allows split operation
using the two internal VFOs.
(18) PRI
While operating in the dial tuning mode, the
PRIORITY switch allows scanning of the main
dial and one of the memorized frequencies every 7
seconds, The SCAN switch controls the stopping
of the scanner on a busy or clear channel.
(19) F.SET
This switch, when pressed, clears all digits of the
operating frequency below the step frequency you
are using.
(20) HI/LOW
This switch, when pressed, reduces the transmitter
power from 10 watts to 1 watt RF output.
(21) MR (Memory Recall)
This button transfers frequency control from the
main dial to the memory channels.

UNDERSIDE CABINET SWITCHES
(1) SAT (Satellite)
This switch allows the operating frequency to be
(2) 3) changed while transmitting. This feature is useful
especially for satellite operation, for it allows the
operator to zero on the proper frequency within
the satellite passband. Neither VFO A/B TXA nor
the CLARIFIER function works when the SAT
switch is placed in the ON position.
(2) SCAN
This switch will select scanning stop on a busy or
clear channel in the FM mode. Manual scanning
stop 1s also provided on all modes.
(3) BURST
The BURST switch applies a short “tone burst” to
the carrier at the start of each transmission in the
“ON” position. This is normally used only for
“tone access” repeater actuation.

INSTALLATION
ANTENNA CONSIDERATIONS
The FT-780R ıs designed for operation using an
antenna presenting a 50 ohm resistive load. The
automatic final transistor protection circuitry will
reduce the power output to protect the transistors
when a high antenna SWR is encountered, The
SWR on the antenna should, if possible, be kept
below 1.5 : I at all times to secure full output
from the transceiver,
In most cases, coverage is a function of antenna
height. The antenna for base station operation
should be located as high and jn the clear as
possible. Vertical polarization is standard for FM
communications in most areas, so be sure that your
antenna is oriented appropriately. Popular anten-
nas for base station use include the 5/8 wavelength
vertical or one of the many stacked dipole arrays.
For accessing repeaters a long distance away, a
Yagi or other high gain directional array may be
required.
For mobile applications, the most popular anten-
nas are the 1/4 wavelength vertical and the 5/8
wavelenght vertical, which shows approximately
3 dB gain over the 1/4 wavelength vertical.
Do not economize on coaxial cable, 4s much
power can be wasted in lossy transmission line,
For mobile use, the RG-58A/U type of coax may
be used. To minimize loss, use the shortest length
that is possible. For base stations, use type RG8A/
U coaxial cable. For very long runs, type RG17A/
U, aluminum-jacketed “foamflex” coax, or air
dielectric “heliax’’ cable may be used.

MOBILE INSTALLATION
For mobile service, the FT-780R should be in-
stalled where the digital display, controls, and
microphone are easily accessible for operation.
The transceiver may be installed in any position
without loss of performance. A suitable location
would be stop the transmission tunnel. A universal
bracket is supplied with your transceiver for
mobile installation. Refer to Fig. 1 for mounting
details.
1. Use the universal mounting bracket as a
template for positioning the mounting holes,
Use a 3/16” diameter bit for drilling these
holes, allowing clearance for the transceiver,
its cables and microphone, and its controls.
Secure the mounting bracket with the screws,
washers, and nuts supplied, as shown in the
drawing.
ho
Ease the transceiver into the guide rail, and
slide it into the desired position. Tighten the
knobs on the outside of the universal bracket
Lo secure the transceiver.
3. The microphone hanger may be installed
wherever convenient for access to the micro-
phone.
Power connections should be made directly to the
automobile battery. Routing through the cigarette
lighter may cause the lighter fuse to blow if the
fuse is not of sufficient rating. As well, connection
directly to the battery allows the memory circuits
to remain activated when the ignition is turned off,
using the BACKUP switch.

may be connected to the rear apron SP jack, 1f
desired. Use the speaker plug supplied with the
transceiver. Insertion of a plug into this jack auto-
matically cuts off the internal speaker.
BASE STATION INSTALLATION
A base station mounting stand Is supplied with
your transceiver, to provide easier viewing of the
display and controls. A power supply capable of
supplying 5 amps at 13.8 VDC is required for
operation from AC mains. The FP-80A AC power
supply option provides the required 13.8 VDC for
the FT-780R transceiver. See your Yaesu dealer.

OPERATION
The all solid-state design of the FT-780R means
that tuning procedures are very simple. The follow-
ing paragraphs will describe the tuning procedures
for receiver and transmitter operation.
INITTAL CHECK
Before connecting the transceiver to the power
supply, be certain that a fuse of the proper rating
15 in use, and that a 50 ohm antenna has been
connected to the antenna jack.
FREQUENCY SELECTION USING MAIN DIAL
When the transceiver is initially turned on, the
digital display will read the preset frequency
*445.000.0 MHz, and frequency control will be via
the main tuning dial. After memory, scanning, or
priority operation, pressing the DIL button will
return control to the main dial. Rotate the dial to
secure the operating frequency desired. Since tun-
ing steps depend on the combination of the MODE
switch and STEP switch as shown in Table 1, use
the synthesizer step for easy tuning. When the
upper or lower bandedge is reached the next
synthesizer step will automatically be to the
opposite bandedge. Thus, after *449.999.9 MHz,
the next step is 440.000.0 MHz. While transmit-
ting, the operation frequency can not be changed
in any operation modes except the satellite mode.
* A model.
RECEIVER OPERATION
Preset the controls and switches as follows:
MODE .......... Desired mode
SQL ............ Fully counterclockwise
STEP ........... Desired synthesizer step
VFO A/B TXA .... VFO “A” position
SCAN .......... . MAN position
All other switches should be turned off initially.
Rotate the VOL control clockwise to turn the
transceiver on and adjust for a comfortable level.
(1) SSB mode
Using the main tuning dial, tune in an SSB signal.
The STEP switch should be set to M or F position
so that you can secure the operating frequency
— {0 —
desired in 100 Hz or 1 kHz steps. When you get
close to the desired frequency, set the STEP switch
to S position for 10 Hz step in order to tune in the
signal smoothly. When pulse type noise such as
ignition noise is encountered, press the NB (noise
blanker) switch.
(2) CW mode
With the clarifier off, tune in a CW signal. When
the incoming signal is tuned to a beat note of
800 Hz, your transmit frequency will coincide with
that of the other station. If another beat note is
desired, or И the other station drift, then use the
clarifier function.
(3) FM mode
Using the main tuning control, tune in an FM
signal for a maximum and steady S-meter reading
and a clear, natural voice output from the speaker.
Set the STEP switch to the M (25 kHz) position,
as almost all FM stations use 25 kHz steps. When
you change the operating mode from SSB/CW to
FM, all the digits of the operating frequency below
10 kHz will be set to zero by pressing the F.SET
button.
When the channel is clear, rotate the SQL control
to the point where the background noise 1s just
silenced. Do not rotate the SQL control much
beyond this threshold point, or else the receiver
will not respond to weak signals. The BUSY/MOD
lamp will light up when the squelch circuit 1s
opened. If the S-meter wobbles, or if it is impos-
sible to obtain clear audio, it 1s possible that the
incoming signal is on another mode such as SSB,
TRANSMITTER
Before transmission, be certain that the frequency
on which you are going to operate is clear to
prevent interruption of the other station’s opera-
tion. It is important that an antenna or dummy
load be connected to the antenna jack at all times.
(1) SSB mode
Set the MODE switch to SSB and close the micro-
phone PTT switch; the ON AJR lamp should light
up. Speak into microphone in a normal voice;
the SPO LEDs will light up according to the
relative output power.
for free by
RadioAmateur.eu
(2) CW mode
Plug a key into the KEY jack on the rear panel.
In the key-down condition, the 8-9 LEDs of the
indicator wil light up. Since the semi-break-in
circuit is furnished, when the key is closed, your
keying activates the transmitter, and the 800 Hz
side tone will be heard from the speaker. With the
HI/LOW switch pressed, the power output of 10
watts may be reduced to 1 watt, and the LOW
lamp will light up.
(3) FM mode
Set the MODE switch to FM, and close the micro-
phone PTT switch. When transmitting, 8-9 LEDs
which show relative output power will light up,
and BUSY/MOD lamp will be illuminated accord-
ing to the voice input. On this mode, 10 watts of
RF output power can also be reduced to 1 watt by
pressing the HI/LOW button,
MEMORY OPERATION
A total of four memory channels are available for
operation. Storage and recall of memory channels
allows considerable operating flexibility. The
storage and recall procedure 1s extremely simple.
(1) Rotate the main tuning dial to the desired
frequency, for example 446.640.0 MHz. Now
rotate the MEMORY switch to position ].
Press the M button to store 446.640.0 MHz
into memory channel position 1.
(2) Now rotate the main tuning dial to another
frequency (for example 446.360.0 MHz). For
instant return to 446.640.0 MHz, press MR
button, the 446.640.0 1 will be displayed on
the digital readout.
To return again to 446,360.0 MHz, press
DIL, and you will be operating on 446.360.0
MHz.
(4) Memory channels 2, 3 and 4 may be program-
med and recalled as above.
(5) When you push the MR button, the far right
LED on the readout will illuminate, indicating
the memory channel.
(6) To return frequency control to the main tun-
ing dial, push the DIL button.
- 11 -
(7) Set the STEP switch to the desired step
before activating the clarificr in the memory
operation. Changing the synthesizer step with
the CLAR switch ON will lock the operating
frequency.
SCANNER OPERATION
Fingertip switches, located on the microphone,
allow convenient frequency control while driving.
The simple operating procedure is describer below.
(1) Set the bottom panel SCAN switch to the
MAN position. Push the DIL switch to select
operation on the dial frequency.
(2) Press the microphone UP switch for an instant
to shift the frequency up by one step. If you
hold the UP bution for more than }/2 second,
the scanner will be activated. To stop the
scan, press the PTT switch or one of the
scanning controls on the microphone. П you
push the PTT switch, no transmission will
occur; release the PTT switch, then press it
again for normal transmission.
(3) To scan lower in frequency, use the same
procedure, but press the DWN button.
(4) In the FM mode, to halt the scan automatical-
ly on a busy channel, set the bottom panel
SCAN switch to BUSY. In this mode, when
the scanner encounters a signal strong enough
to open the receiver squelch, scanning will
stop. When the bottm panel switch is placed
in the CLEAR position, the scan will stop
when a clear channel (one where the squelch
wil! not open) is found.
(5) To scan only the memory channels, rotate the
MEMORY switch to the MS (memory scan)
position. Now press the UP or DWN switch on
the microphone. The scanning rate for memo-
ry scan will be approximately two channels
per second. The scan may be halted in any of
the ways discussed previously. The BUSY and
CLEAR positions of the SCAN switch are
particularly helpful when scanning the memo-
ry channels tn the FM mode.

PRIORITY CHANNEL OPERATION
A priority channel may be used in conjunction
with a memory channel for increased flexibility.
Here is how to set up the FT-780R for priority
operation.
(1) First program one or more memory channels
for priority use. For example, store 446.640.0
MHz into memory channel 1. Set the bottom
panel SCAN switch to MAN. Rotate the main
dial to the desired frequency (for example
446.360.0 MHz).
(2) Now set the MEMORY switch to 1 and push
MR to recall 446,640.0 MHz; now push the
PRI (priority) switch. The display will indi-
cate 446.360.0 P, and every 7 seconds the
display will switch to 446.640.0 MHz allow-
ing you to check it for activity.
(3) If you have other frequencies stored in
memory, you may rotate the MEMORY
switch to select one for use with the priority
channel.
(4) In the FM mode, you may use the SCAN
switch to good advantage during priority
operation, as described in SCANNER OPERA-
TION.
(5) If you wish to return to normal operation
from the priority mode, push the DIL button.
Now control is shifted back to the main dial.
REPEATER OPERATION
(1) Repeater shifts of +5 MHz (+7.6 MHz), and
- 5 MHz ( 7.6 MHz) are built into the FT-
780R. To select these shifts, set the bottom
panel RPT switch to the + or — position
respectively.
To cover unusual repeater splits, you can use
the VFO A/B TXA feature.
Example: receive frequency 448.640 MHz
with 1 MHz split. Rotate the main tuning dial
to the 447.640 MHz and press the VFO A/B
TXA button on the front panel; now the
transmit frequency, 447.640 MHz, is memo-
rized. Rotate the main tuning dial to 448.640
MHz for receiving. If you close the PIT
switch, your transmit frequency will be
shifted to 447.640 MHz.
(3) A 1750 or 1800 Hz tone generator is included
with your transceiver for accessing repeater
requiring such a tone. When the T.CALL
switch is pushed, a tone will be superimposed
on your transmitted signal. This switch also
activates the PTT function, and transmits the
access tone, for as long as the switch is held,
An external tone or burst generator, optional
FTS-64E may be connected through the rear
panel TONE IN CONNECTOR.
INITIALIZING FREQUENCY/BACKUP
FEATURE
The FT-780R includes a backup feature which
№1] hold all memory frequencies, as well as dia)
frequency, when the front panel power switch is
turned off. So long as the DC power to the rear
apron power jack is not interrupted, these fre-
quency will be held. When the power is again
turned on, the frequency and mode (memory
priority, dial, etc,) last used will be recalled, but
scanning mode is automatically reset to dial mode.
However, if the power cord is connected to 13.8
VDC circuit that is switched off along with the
automobile ignition, all memory channels as well
as the dial frequency will be reset to the preset
frequency.
SATELLITE OPERATION
The FT-780R includes provision for changing the
transmitting frequency while you arc transmitting
(some other synthesized transceivers lock up dur-
ing transmission). The ability to change frequency
in this manner is important during satellite opera-
tien, as Doppler shift may cause your downlink
frequency to be +3—4 kHz from a predicted value.
While listening on the downlink, and sending a
series of dots, satellite operators can usually find
themselves quite quickly.
To allow frequency change during transmission, set
the bottom panel SAT (Satellite) switch to ON.
For most satellite work on SSB or CW, the synthe-
sizer step switch should be set to Slow or Medium.
You may now close the PTT switch and vary your
frequency as desired. Note that your receiver fre-
quency will also change if you rotate the main dial.
When the SAT switch is set to ON, the + repeater
shift and receive clarifier features are disabled.

CIRCUIT DESCRIPTION
The block diagram, and circuit description to
foliow will provide you with a better understand-
ing of this transceiver. Please refer to the block
and schematic diagrams for specific circuit details.
RECEIVER
The RF signal from the antenna jack is applied to
the PLL UNIT through a low pass filter and the
antenna relay, RlLyooı - The signal is amplified by
О! (3SK97), a dual gate GaAs FET with excel-
lent rejection of cross modulation and mtermodula-
tion. The amplified signal is fed to the Ist mixer,
Qz002 (2SK125), where the RF signal is mixed
with a local signal delivered from Q3003 (28C2407),
resulting in a 67.6] MHz first IF signal.
The first LF signal is amplified by Q,ooı (3SK73Y)
and then passed through a stagger tuned bandpass
filter to the second mixer Q 00,(25K125). The signal
is then mixed with a second local signal of 56.91
MHz, which is delivered from buffer Qyoo4
(28C460), thus producing a second IF signal
(10.7 MHz).
The 2nd IF signal is passed through a monolithic
crystal filter, ХЕ: (10M30B), which has #15
kHz bandwidth, and amplified by Q 005 (3SK73Y),
which acts as a switch driven by the NB (noise
blanker) circuit. The amplified signal from Qyoos 15
fed to JF amplifiers for each mode.
FM mode signals are fed to 3rd mixer Qioos
(2SC460), where the signal is mixed with a 10.245
MHz local signal, resulting in a 455 kHz 3rd IF
signal.
The 3rd IF signal is passed through a ceramic filter,
CFE oo, , Which has a +4.5 kHz bandwidth, and then
fed to the FM mode IF amplifier.
The filtered signal is amplified by Qiao, (2SC945Q)
and passed through CF, 992, which has a +7.5 kHz
bandwidth. The filtered FM signal is amplified by
Q,009 (uPC577H) and demodulated by CD 001 and
Divo, Dj003 (1S188FM). The demodulated FM
signal is amplified by Q;o14 (28C1815GR) and
then fed to the AF amplifier.
SSB and CW mode signals from the Qjoos are
passed through a crystal filter, XF ¡00 , which has а
very high shape factor, fo improve adjacent fre-
quency selectivity. The filtered SSB signal is
amplified by Qjoig and Q19,;7 (3SK73Y), and then
fed to the balanced demodulator, Osos
(„PC1037H), where a carrier signal is applied from
the carrier oscillator Q 073 (28C945P); the detected
audio output is then fed to the AF amplifier.
The audio signals from each demodulator are
passed to the active lowpass filter, which consists
of QO,o2a and О:о25 (2509450) to eliminate the
unwanted noise portion of the signal. The audio
signal is then fed, through the AF gain control, to
the audio output amplifier, Q3o09 (uPC2002H),
providing about 2 watts of audio output to the
speaker.
S-METER CIRCUIT
A portion of the amplified IF signal is fed to Q;019
(2SC535B), a buffer amplifier, through Cyog9. The
amplified signal is then applied to the AGC
detector, Do /Dio1o (JSIS8FM). The rectified
signal 15 amplified by DC amplifier Quo (2SC-
2785E) for AGC control. This AGC voltage is
delivered to the front panel S.PO indicator to illu-
minate LEDs according to the input signal strength.
SQUELCH CIRCUIT
A portion of the demodulated FM signal from the
ceramic discriminator (CD 001, Diooı : Dio02 ) 15 fed
to noise amplifiers Qigio and Ojo (2SC945P)
through VRio and the SQ Control (VR, ,), and
then rectified by Ojo. (284564). The rectified
signal is fed to the base of Оз (2SC945P), the
squelch control circuit.
When no carrier is present, the rectified DC voltage
is applied to the base of Ojoja, to turn Qioia
(2SC1815GR) on. With conduction of Оо, the
base of Qioi4 is grounded, squelching the audio
amplifier.
When a carrier is present, the rectified DC voltage
is reduced, the audio amplifier Q 014 then recovers
to normal operation. The BUSY lamp switch,
Qiors (2SC945P), is also activated by the rectified
voltage from the demodulator to Шиттае the
BUSY lamp when a carrier is present.

NB (Noise Blanker) CIRCUIT
A portion of the 2nd IF signal from monolithic
filter XF 001, 15 amplified by Оо, (2SC535B),
Qios2, Qi063, and Qioss (28C1583). The output
signal is rectified by Dyoas and Dios (1S188FM),
producing a DC voltage. This DC voltage is
amplified by Qioes (MPSA 13) and fed to gate 2 of
Qioos, the noise blanker gate. A portion of the
DC voltage is amplified by О (25C945P), and
then fed to Qjo62, Qıası (2SC1583) as a noise
blanker AGC voltage. When impulse-type noise is
received, the induced DC voltage reduces the gain
of Qıoos, and blocks the signal path momentarily.
The noise AGC control voltage is not, however,
induced by such impulse-type noise, because the
time constant of Cyso4/Ri2s7 is long. Normal
signals, though, induce the noise blanker AGC
voltage, reducing the gain of the noise amplifier,
allowing normal signal flow at Qyoos.
TRANSMITTER
The discussion of the signal flow on transmit will
be on a mode by mode basis.
SSB
The audio input signal from the microphone is
amplified by Q,o2s (28C1815GR) and O,0.9 (2SC-
945P), the audio level is adjusted to the proper
level by УК, од, avd 1$ applied through an active
lowpass filter. Ojo (2SC945P), to the double
balanced modulator Оз. (MC1496P). Here the
audio signal modulates the 10.7 MHz carrier signal
delivered from the carrier oscillator О\о23 (2SC-
945P), resulting In a 10.7 MHz double-sideband
signal. The signal is amplified by Q,038 (2SK19TM-
GR) and fed to ХЕ, оз, a crystal filter, where the
unwanted sideband is sliced out. The SSB signal is
amplified by Ош» (3SK73), and then fed to mixer
O ¡04 (MC1496) and mixed with a local signal from
the PLL Unit. resulting in a 67.61 MHz SSB signal.
The SSB signal is passed through Tios —Тлонв,
which minimizing spurious radiation. The signal is
then amplified by Qio4, (3SK73Y), and fed to PLL
unit.
The SSB signal applied to mixer D;513 - Dots
(15597) is mixed with the local signal from the
PLL circuit, resulting in a proper operating fre-
quency. Next the signal is buffered by Qso04
(2SK125), and fed through cavity CV 4993, which
eliminates spurious harmonics, thus providing a
clean SSB signal. The signal is then amplified by
Qs005 (28C2026) and Qyo96 (25C1426) to the level
necessary to drive the power amplifier circuit.
FM
The output audio signal at Qios is amplified by
Q,osı (2SC1815GR) and Qio3. (2SC945P) and fed
to IDC circuit, consisting of Dos and Dio,
which clips both positive and negative peaks to
control the maximum possible deviation; the
clipped signal is then passed through an active
lowpass filter to eliminate harmonics above the
speech range caused by clipping. The output signal
is amplified by Q;,533 (28C945P) to a sufficient
audio level and applied to the FM modulation
module XM,oo,; for modulation, and the maximum
deviation is adjusted by VRio0 prior to delivery
to Q,535. The signal path is then identical to that
of the SSB signal.
CW
For CW, the 10.8107 MHz carrier signal is
generated by Ojos (2SC945P), amplified by О: оз;
(2SC945P), and fed to IF amplifier Q,oss- The
signal path is then identical to that of the SSB
signal.
The key line is connected to switching transistor
QOioss (2SC945P) through inverter Оо
(MC14011B), which controls the gate voltages at
Qio39 (3SK73) and Qyoaı (3SK59Y), thus turning
the RF signal on and off.
An RC circuit connected to the base of O,oss
produces an ideal keying waveshape for click-free
CW operation. The key line is also connected to
side tone oscillator Q,o55 (MC14069UB) for

RadioAmateur.eu
monitoring of the code signal during CW operation.
In order to operate on semi-break-in, the Schmitt
trigger and delay circuit at Q;os activates the
RX-TX changeover relay.
POWER AMPLIFIER CIRCUIT
The RF signal from the Main Unit is amplified by
О: (M57716) in the Power Amplifier Unit,
delivering approximately 10 watts of RF output to
the antenna through a lowpass filter.
POWER CONTROL CIRCUIT
When the HI/LOW switch is set to the LOW posi-
tion, the base of Q,oa4 is grounded through VR;50,
and the collector current of Ojos, is decreased.
Because the output power of О.о: is controlled
by Qioaa, the drive level to Q3001 is decreased, thus
reducing the RF output power to approximately
| watt.
TONE BURST CIRCUIT
When the T.CALL switch is pressed, the base of
О1о4‹ (2SA564A) is grounded, and DC voltage 1$
applied to tone burst oscillator Qio47 (TC5082P)
to generate a 1750 Hz or 1800 Hz tone signal. The
tone is superimposed on the transmit signal as long
as the switch 1s held.
ALC (Automatic Level Control) CIRCUIT
A portion of the output power from Qyon; 15
applied through strip line to rectifier Drop] (18597)
producing a DC voltage. The DC voltage is ampli-
fied by DC amplifier Q 032 (2SC1815Y) and fed to
gate 2 of Q.1o39 to control its ват, thus preventing
overdrive. The ALC level 1s adjusted by VRioog for
proper drive to Qyoo; .
AFP (Automatic Final Protection) CIRCUIT
If the transmitter is activated without an antenna
being connected, or if a high VSWR is present at
the antenna jack, the reflected power is coupled
through a stripline fo detector, Doyo, (158897).
18 —
The detected AFP voltage is applied through
VR3902 10 Qio43 (2SC94SP) in the Main Unit. As
the reflected power increases, the AFP voltage also
increuses, and consequently Qyo43 conducts. The
voltage at gate 2 of О\озо (3SK73Y) then decreases.
resulting in lower output power. When the trans-
celver is correctly matched to an antenna, full
power output will be obtained.
PLL CIRCUIT
The PLL circuit 1s comprised of three PLL oscil-
lators each consisting of a reference crystal oscil-
lator, a programmable divider, a prescaler, and a
phase comparator. The PLL produces local signals
for the receiver and transmitter stages. using a
synthesis scheme which produccs 10 Hz steps.
PLL Circuit Configuration
Voltage Controlled Oscillator VCO-1, consisting of
Qyroı (2SKI9TM), D:002 /D:003 (1T25), and as-
sociated circuitry, generates a signal at 128.80 —
124.13 MHz. This signal is multiplied by a factor
of three at Oz019 (28C2026), then fed through a
bandpass filter to eliminate spurious responses.
The filiered signa! is then amplified by Q3o2.0 and
Q3007 (25802060), passed through another bandpass
filter, then amplified further by Qs00s (2SC2047)
prior to delivery to the receiver first mixer, Q:2602
(2SK125) or the transmit mixer, ОВ! — Daoıs
(15897).
A portion of the signal from buffer Q300% is
amplified by О.о’ (2SC2026) and applied to
mixer Oz30,2 (SN16913), where the VCO signal is
mixed with a local signal at 106.18 MHz delivered
from Озо27 (28C3027). The resulting signal at
14.62—17.95 MHz is. in turn, delivered to another
mixer, O3023 (SN16913), where the 14.62—17.95
MHz signal is mixed with a local signal at 11.28—
11.68 MHz from PLL Loop 2. The resulting PLL
IF signal at 3.333—6.667 MHz is fed through a low-
pass filter, consisting of Laoag, [3049 , Caraı , Сз132 ,
and Czj33, then amplified by Оз. (2SC535B).
The output from Q:3624 1$ then fed to a program-
mable divider, Q35,, (1C9122P), where the PLL IF
signal is divided according to the ratio programmed
by the Central Processing Unit (CPU).
for free by
RadioAmateur.eu
VCO-2 consists of Оз,» (2SK19TM), D3o02 /Daoo3
(1T25). providing a signal at 112.8—116.2 MHz.
The УСО signal is buffered through Oo:
(3SK73Y) and Q,,,. (2SC535B), while a portion
of the output from Q3011 Is amplified by Ossıs
(2SC535B) in order to drive the 1/10 divider,
0. :- (HD10551), wherc the 112 MHz signal is
divided by 10 and delivered to mixer Озо2 in PLL
Loop l.
The buffered output from Озон» is fed to the PLL
Loop 2 local mixer, O3013 (SN16913), where the
112 MHz signal is mixed with a local signal at
106.18 MHz, generated by Q392.,. The output from
the mixer, at 6.667 10.000 MHz, is passed through
a low-pass filter to IF amplifier Оз. (2SC535B).
The amplified signal is then applied to a program-
mable divider, Ооо (TC9122P), which divides the
frequency by a factor of 2000—3000, resulting in a
3.333 kHz signal. This signal is applied to a phase
detector, Озо,5 (1C5081P), where it is compared
with a reference 3.333 kHz signal delivered from
Q3032 (MC14518). Any phase difference is con-
verted info an error-correcting voltage, which Is
used to control varactor diodes in the PLL, locking
the PLL on the proper frequency.
PLL local oscillator/tripler Озо27 (28C535B) oscil-
lates either in 3 Hz steps (for control of PLL Loop
1) or 0.3 Hz (to control PLL Loop 2). The
resultant synthesis provides local oscillator steps
of 10 Hz.
The CPU command signals, which control the
dividing ratio of Qso41, are converted into series by
Q3037 03039 (MC14094). The control signal is also
delivered to programmable divider Q:640 in PLL
Loop 2 and to the VCXO oscillator/tripler, Q 3027.
When any VCO is unlocked, an error voltage from
the phase detector 1s fed to the unlock control
circuit, consisting of Q:6:8 (28A733) and Озоло
(28C955). The amplified DC voltage is applied to a
key control circuit so as to disable transmit
capability under conditions of PLL unlock.
PLL Control Circuit
In the PLL Control Unit, a 4 bit parallel processing
CPU is used to control the operating frequency,
UP/DOWN scanning, priority channel, or memory
channel selections. The CPU has one input port,
three I/O ports and four output ports. The CPU
processes input data by means of the main dial or
other control switches in accordance with the
program stored in an ROM for control of the PLL
frequency, indication of the operating frequency,
or memory channels on digital display. The CPU
is also furnished with a function to halt transmis-
sion when any VCO is unlocked, resulting in a
fail-safe system.

This equipment has been carefully aligned and
tested at the factory prior to shipment. If the
instrument is not abused, it should not require
other than the usual attention given to electronic
equipment.
Service or replacement of a major component may
require considerable realignment. Under no circum-
stances, though, should realignment be attempted
unless the operation of the transceiver is fully
understood, the malfunction has been carefully
analyzed, and the fault has definitely been traced
to misalignment rather than part failure. Service
work must only be performed by experienced
personnel using the proper test equipment.
Never align this transceiver without having a 50
ohm dummy load connected to the antenna jack,
unless otherwise noted. Troubleshooting using an
antenna can result in misleading indications on test
equipment.
