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
transceiver’s front end.

CIRCUIT DESCRIPTION
The signals from the RF circuit are mixed at the 1st mixer
(Q13) with a 1st LO signal coming from the VCO circuit to
produce a 30.85 MHz 1st IF signal.
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
Received signals passed through the low-pass filter (L1–L3,
C1–C7). The filtered signals are applied to the λ/4 type
antenna switching circuit (D8, D32, L15, L16, C76–C78).
The 1st IF signal is applied to a crystal filter (FI1) to suppress
out-of-band signals. The filtered 1st IF signal is applied to the
IF amplifier (Q14), then applied to the 2nd mixer circuit (IC2,
pin 16).
The antenna switching circuit functions as a low-pass filter
while transmitting. However, its impedance becomes very
high while D8 and D32 are turned ON. Thus transmit signals
are blocked from entering the receiver circuits. The antenna
switching circuit employs a λ/4 type diode switching system.
The passed signals are then applied to the RF amplifier circuit.
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal. A double conversion superheterodyne system (which
converts receive signal twice) improves the image rejection
ratio and obtains stable receiver gain.
4-1-2 RF CIRCUIT
The 1st IF signal from the IF amplifier is applied to the 2nd
mixer section of the FM IF IC (IC2, pin 16), and is mixed with
the 2nd LO signal to be converted to a 450 kHz 2nd IF signal.
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals.
The signals from the antenna switching circuit pass through
a bandpass filter (D10, L26) after being amplified at the RF
amplifier (Q29). The filtered signals are amplified at another
RF amplifier (Q12), then applied to the 1st mixer circuit after
out-of-band signals are suppressed at the bandpass filter
(D11, D12, L18, L19, C92, C94, C96, C236).
The FM IF IC contains the 2nd mixer, limiter amplifier, quadrature detector and active filter circuits. A 30.4 MHz 2nd LO
signal is produced at the PLL circuit by doubling it’s reference
frequency.
D10–D12 employ varactor diodes that track the bandpass filters and are controlled by the T4/PWR signal from the CPU
(IC8, pins 54–59). These diodes tune the center frequency of
an RF passband for wide bandwidth receiving and good
image response rejection.
The 2nd IF signal from the 2nd mixer (IC2, pin 3) passes
through a ceramic filter (FI2) to remove unwanted heterodyned frequencies. It is then amplified at the limiter amplifier
(IC2, pin 5) and applied to the quadrature detector (IC2, pins
10, 11) to demodulate the 2nd IF signal into AF signals.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
4-1-5 AF CIRCUIT
The AF amplifier circuit amplifies the demodulated AF signals
to drive a speaker.
The 1st mixer circuit converts the received signal to a fixed
frequency of the 1st IF signal with a PLL output frequency. By
changing the PLL frequency, only the desired frequency will
pass through a crystal filter at the next stage of the 1st mixer.
AF signals from the FM IF IC (IC2, pin 9) are applied to the
analog switch (IC4, pin 1) via the AF filter circuit (IC3b, pins
6, 7). The output signals from pin 11 are applied to the AF
power amplifier (IC5, pin 4) after passing through the [VOL]
control (VR board, R1).

The AF signals from the [VOL] control are applied to the AF
power amplifier circuit (IC5, pin 4) to obtain the specified
audio level. The amplified AF signals, output from pin 10, are
applied to the internal speaker (SP1) via the [SP] jack when
no plug is connected to the jack.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis characteristics from the microphone to a level needed for the modulation circuit.
The AF signals from the microphone are applied to the microphone amplifier circuit (IC3c, pin 10). The amplified AF signals are passed through the low-pass filter circuit (IC3d, pins
13, 14) via the analog switch (IC4, pins 2, 3). The filtered AF
signals are applied to the modulator circuit after passing
through the analog switch (IC4, pins 8, 9) and the deviation
adjustment pot (R119).
4-1-6 SQUELCH CIRCUIT
A squelch circuit cuts out AF signals when no RF signals are
received. By detecting noise components in the AF signals,
the squelch switches the analog switch.
A portion of the AF signals from the FM IF IC (IC2, pin 9) are
applied to the active filter section (IC2, pin 8) where noise
components are amplified and detected with an internal
noise detector. The squelch input level adjustment pot (R92)
is connected in parallel to the active filter input (pin 8) to control the input noise level.
4-2-2 MODULATION CIRCUIT
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signal.
The trigger circuit converts the detected signals to a HIGH or
LOW signal and applies this (from pin 13) to the CPU (IC8,
pin 19) as the NOIS signal. When the CPU receives a HIGH
level NOIS signal, the CPU controls the RMUT line to cut the
AF signals at the analog switch IC (IC4). At the same time,
the AFON line controls the AF regulator circuit (Q15, Q16) to
cut out the VCC power source for the AF power amplifier
(IC5).
The audio signals (SHIFT) change the reactance of D6 to
modulate an oscillated signal at the VCO (Q7, Q8). The oscillated signal is amplified at the buffer-amplifiers (Q4, Q6),
then applied to the T/R switching circuit (D3, D4).
4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS
The signal from the VCO circuit passes through the T/R
switching circuit (D3) and is amplified at the buffer (Q3), drive
(Q2) and power (Q1) amplifiers to obtain 5.5 W (4.5 W:
Thailand only) of RF power (at 9.6 V DC/typical). The amplified signal passes through the antenna switching circuit (D1),
and low-pass filter (L1–L3, C1–C7) and is then applied to the
antenna connector (J1).

A portion of the VCO signal is amplified at the buffer-amplifier (Q4, Q6) and is then applied to the receive 1st mixer or
transmit buffer-amplifier circuit via the T/R switching diode
(D3, D4).
4-2-5 APC CIRCUIT
The APC circuit (IC3a, Q37) protects drive and power amplifiers from excessive currents and selects HIGH or LOW output power.
The output voltage from the current detector circuit is applied
to the inverting amplifier (IC3a, pin 2), and the T4/PWR signal from the CPU (IC8, pins 54–59) is applied to the other
input for reference.
4-4 POWER SUPPLY CIRCUITS
VOLTAGE LINE
When the driving current increases, the input voltage of the
differential amplifier (Q9, pin 1) will be decreased. In such
cases, input voltage of the inverting amplifier (pin 2) is
increased to decrease the output power.

Q37 is controlled by the TXC signal from the CPU (IC8, pin
50) to select HIGH or LOW output power.
4-3 PLL CIRCUIT
A PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL output compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by
the divided ratio (N-data) of a programmable divider.
The PLL circuit contains the VCO circuit (Q7, Q8, D6). The
oscillated signal is amplified at the buffer-amplifiers (Q5, Q6)
and then applied to the PLL IC (IC1, pin 2).
The PLL IC contains a prescaler, programmable counter, programmable divider, phase detector and charge pump, etc.
The entered signal is divided at the prescaler and programmable counter section by the N-data ratio from the CPU. The
divided signal is detected on phase at the phase detector
using the reference frequency.
If the oscillated signal drifts, its phase changes from the reference frequency, causing a lock voltage change to compensate for the drift in the oscillated frequency.
