NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than 10 V. This will ruin the
transceiver.
DO NOT reverse the polarities of the power supply when
connecting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100 mW)
to the antenna connector. This could damage the trans-
ceiver's front end.
1. Make sure a problem is internal before disassembling the transceiver.
2. DO NOT open the transceiver until the transceiver is disconnected from its power source.
3. DO NOT force any of the variable components. Turn them slowly and smoothly.
4. DO NOT short any circuits or electronic parts. An insulated turning tool MUST be used for all adjustments.
5. DO NOT keep power ON for a long time when the transceiver is defective.
6. DO NOT transmit power into a signal generator or a sweep generator.
7. ALWAYS connect a 40 dB to 50 dB attenuator between the transceiver and a deviation meter or spectrum analyzer when
using such test equipment.
8. READ the instructions of test equipment thoroughly before connecting equipment to the transceiver.
To upgrade quality, any electrical or mechanical parts
and internal circuits are subject to change without
notice or obligation.

SECTION 4CIRCUIT DESCRIPTION
4-1 RECEIVE CIRCUITS
4-1-1 ANTENNA SWITCH (RF UNIT)
The received signals from the antenna connector are
passed through the antenna switch which toggles the
receive (RX) line and transmit (TX) line.
The received signals from the antenna connector are
passed through the low-pass filter (LPF; L81, L82, C80, C83
−C86, C89, C226) and the antenna switch (D52, D90 and
D353 are OFF).
While transmitting, the voltage on the T5V line is applied to
D52, D90 and D353, and these are ON. Thus the TX line is
connected to the antenna, and RX line is connected to the
GND to prevent transmit signal entering.
While receiving, no voltage is applied to D52, D90 and
D353, and these are OFF. Thus the TX line and the antenna
is disconnected to prevent received signals entering, and
RX line is disconnected from the GND and L90, L91, C90
−C92 compose a two-staged LPF which guides received
signals to the RX circuits.
The received signals are applied to the RF circuits.
4-1-2 RF CIRCUITS (RF UNIT)
The RF circuit amplifies received signals within the frequency
coverage. The received signals are filtered at the bandpass
filter (BPF) and amplified at the RF amplifier.
The received signals from the antenna switch are passed
through the two-staged tunable BPF (D92, D93, L92, L93,
C95, C97−C101) to filter out unwanted signals. The filtered
signals are applied to the RF amplifier (Q90). The amplified
signals are then applied to the 1st mixer (Q150) via another
two-staged tunable BPF (D130, D131, L96, L97, C104,
C109, C110, C112−C116).
4-1-3 1st IF CIRCUITS (RF UNIT)
The received signals are converted into the 1st IF signal,
and amplified at the 1st IF circuits.
The amplified received signals from the RF circuits are applied

IF signal by being mixed with the 1st local oscillator (LO)
signals from the VCO (Q21, Q22, D21−D23).
The converted 1st IF signal is passed through two 1st IF
filters (FI150, FI151) to filter out unwanted signals, and
applied to the 1st IF amplifier (Q151). The amplified 1st IF

4-1-4 2nd IF AND DEMODULATOR CIRCUITS
(MAIN UNIT)
The 1st IF signal is converted into the 2nd IF signal, and
demodulated.
The 1st IF signal from the 1st IF circuits is applied to the
2nd IF mixer in the FM IF IC (IC170, pin 16) and converted
into the 2nd IF signal by being mixed with the 21.25 MHz
2nd LO signal from the reference oscillator (RF UNIT; IC1,
X1) via LPF (RF UNIT; L1, C8, C9, C12).
The converted 2nd IF signal is output from pin 3, and
passed through the 2nd IF filter (FI170) to suppress
sideband noise. The filtered 2nd IF signal is applied to the
limiter amplifier (IC170, pin 5). The amplified 2nd IF signal
is FM-demodulated at the quadrature detector (IC170,
pins 10, 11) and output from pin 9. The demodulated AF
signals are applied to the AF circuits.

4-1-5 AF CIRCUITS (MAIN UNIT)
The demodulated AF signals from the demodulator circuits are
amplified and filtered in AF amplifier circuits.
The demodulated AF signals from the FM IF IC (IC170, pin 9)
are passed through the AF mute switch (IC260, pins 1, 2),
LPF (IC200, pins 8, 9) and variable register (VR BOARD;
R801) for level adjustment.
The level adjusted AF signals are passed through the
de-emphasis circuit (R286, C280, C285) to obtain −6 dB
of audio characteristic. The de-emphasized AF signals are
passed through the analog switch (IC430, pins 10, 11), and
applied to the AF power amplifier (IC401, pin 7) to obtain
0.6 W of AF output power. The power-amplified AF signals are
then output from pin 1, and applied to the internal speaker via
J251.
If an external speaker-microphone or headset is attached
to the [SP MIC] connector (MIC BOARD; J416), the
de-emphasized AF signals are passed through the analog
switch (IC430, pins 8, 9) and applied to the AF power amplifier
(IC280, pin 4) to obtain 0.2 W of AF output power. The power-
amplified AF signals are output from pin 10, and then applied
to the external speaker via the [SP MIC] connector (MIC
BOARD; J416).
4-1-6 SQUELCH CIRCUIT (MAIN UNIT)
The squelch mutes the AF output signals when no RF
signals are received. By detecting noise components in the
demodulated AF signals, the squelch circuit toggles the AF
power amplifier ON and OFF.
A portion of the demodulated AF signals from the FM IF IC
(IC170, pin 9) are applied to the D/A converter (RF UNIT;
IC190, pin 13) for level adjustment (squelch threshold
adjustment). The level-adjusted AF signals are output from pin
14, and passed through the noise filter (R174−R176, C177,
C179, C180). The filtered noise signals are then applied to
the noise amplifier in the FM IF IC (IC170, pins 7, 8) to be
amplified the noise components only.
The amplified noise components are converted into the
pulse-type signal at the noise detector section, and output
from pin 14 as the “NOISV” signal. The signal is applied
to the CPU (IC360, pin 32), and the CPU outputs “AFVS”
signal from pin 100 according to the “NOISV” signal level, to
the AF power regulator (Q230, Q231, Q401, Q540) which
toggles the AF power amplifier ON and OFF.
4-2 TRANSMIT CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUITS (MAIN UNIT)
The AF signals from the microphone (MIC signals) are
filtered and level-adjusted at microphone amplifier circuits.
The AF signals from the microphone are passed through
the AF mute switch (IC430, pins 1, 2).
While an external microphone is connected to the [SP MIC]
connector (MIC BOARD; J416), the mute switch shuts out
the AF signals from the internal microphone (MC1).
AF signals from the AF mute switch (IC430, pins 1, 2) are
passed through another AF mute switch (IC430, pins 3, 4),
and passed through the pre-emphasis circuit (R253, C254) to
obtain +3 dB of characteristic. The pre-emphasized signals are
then applied to the microphone amplifier (IC200, pins 6, 7). The
amplified MIC signals are passed through AF mute switch
(IC260, pins 8, 9), and are applied to the gain controller
(Q450, Q451) whitch adjust the AF signal level (=deviation)
according to the control signals (“MIC1/2/3”) from the CPU
(IC360, pins 106/107/108).
The level adjusted MIC (MOD) signals are applied to
the limiter amplifier (IC200, pins 13, 14) which limits the
amplitude of the MIC signals to prevent over deviation. The
amplitude-limited MIC signals are then passed through the
splatter filter (IC200, pins 1, 3) which suppresses the 3 kHz
and higher audio components.
The filtered MIC signals are applied to the modulation circuit
(RF UNIT; D20).
4-2-2 MODULATION CIRCUIT (RF UNIT)
The modulation circuit modulates the VCO oscillating signal
with the AF signals from the microphone.
The MIC signals from the microphone amplifier circuits
are applied to the D20, and modulate the VCO oscillating
signal by changing the reactance of D20. The modulated
VCO output signal is buffer-amplified by Q23 and Q24, then
applied to transmit amplifiers as a transmit signal via the
TX/RX switch (D50 is ON, D51 is OFF).

4-2-3 TRANSMIT AMPLIFIERS (RF UNIT)
The VCO output signal is amplified to transmit output power
level by the transmit amplifiers.
The transmit signal from the TX/RX switch (D50) is applied
to the buffer amplifier (Q50). The amplified transmit signal is
amplified to the transmit output level by the pre-driver (Q53)
and power amplifier (Q54). The power-amplified transmit
signal is passed through the TX power detector of APC circuit
(D91), antenna switch (D52, D90 and D353 are ON), TX
power detector for transmit indicator (D80) and LPF (as a
harmonic filter; L81, L82, C80, C83−C86, C89, C226) before
being applied to the antenna connector (CHASSIS; J1).
4-2-1 APC CIRCUIT (RF UNIT)
The APC (Automatic Power Control) circuit stabilizes trans-
mit output power to prevent transmit output power level change
which is caused by load mismatching or heat effect, etc,. The
APC circuit also selects transmit output power from high,
middle and low power.
The power detector circuits (D91) detects the transmit output
and converts it into DC voltage which is in proportion to the
transmit output power level. The detected voltage is applied
to the differential amplifier (IC50, pin 3). The transmit power
setting voltage “PCON” is applied to another input terminal
(pin 1) as the reference voltage.
The differential amplifier compares the detected voltage and
reference voltage, and the difference of the voltage is output
from pin 4. The output voltage controls the bias of the buffer
amplifier (Q50), pre-driver (Q53) and power amplifier (Q54)
to reduce/increase the gain of transmit amplifiers for stable
transmit output power.
The change of transmit power is carried out by the change
of reference voltage "PCON" and "LOW."
4-3 PLL CIRCUITS
4-3-1 VCO CIRCUIT (RF UNIT)
The VCO (Q21, Q22, D21−D23) generates the both of trans-
mit signal and LO signals for the 1st IF conversion. The VCO
output signals are buffer-amplified by Q23 and Q24.
While transmitting, the VCO output signal is applied to the
transmit amplifiers via TX/RX switch (D50 is ON, D51 is OFF).
While receiving, the VCO output signals are applied to the 1st
mixer (Q150) via the TX/RX switch (D50 is OFF, D51 is ON)
the BPF (L26, C122, C123, C130, C131), to be mixed with
the received signals to produce the 21.7 MHz 1st IF signal.
A portion of the VCO output is applied to the PLL IC (IC1,
pin 19) via the buffer amplifier (Q25) and LPF (L20, R20,
C20−C22).
4-3-2 PLL CIRCUIT (RF UNIT)
The PLL circuit provides stable oscillation of the transmit
frequency and receive 1st LO frequency. The PLL output
frequency is controlled by the divided ratio (N-data) from the CPU.
The buffer-amplified signals from the LPF (L20, R20, C20−
C22) are applied to the PLL IC (IC1, pin 19). The applied
signals are divided at the prescaler and programmable
counter according to the “SDATA (SDATAO)” signal from
the CPU (MAIN UNIT; IC360, pin 10). The divided signal is
phase-compared with the reference frequency signal which is
divided by reference counter, at the phase detector.
The phase difference is output from pin 13 as a pulse type
signal after being passed through the charge pump. The
output signal is converted into the DC voltage (lock voltage) by
passed through the loop filter (R8−R10, R22, C10, C11, C24,
C25). The lock voltage is applied to the variable capacitors (D22,
D23) of the VCO (Q21, Q22, D21−D23) and locked to keep
the VCO frequency constant.
If the oscillated signal drifts, its phase changes from that of
the reference frequency, causing a lock voltage change to
compensate for the drift in the VCO oscillating frequency.

4-4-1 VOX CIRCUIT (MAIN UNIT)
The VOX circuit toggles TX and RX automatically by detect-
ing voice signals from the microphone.
The MIC signals from the external microphone are applied
to the VOX amplifier (IC431, pins 1, 2). The amplified MIC
signals are applied to another VOX amplifier (IC431, pin 5),
and the amplified MIC signals are output from pin 7, then
rectified by D430. The rectified signal is applied to the CPU
(IC360, pin 29) as "VOXT" signal which turns the transmit
circuits ON. Then the CPU outputs "VOXM" signal from pin
117 to the AF mute switch (IC430, pin 5) to turn the AF
mute switch OFF, and the MIC signals are applied to the
pre-emphasis circuit.
