To upgrade quality, anyelectrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
DO NOT expose the transceiver to rain, snow or any liquids.
DO NOT reverse the polarities of the power supply when
connecting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100mW)
to the antenna connector. This could damage the transceiver's front end.
ORDERING PARTS
REPAIR NOTES
Be sure to include the following four points when ordering
replacement parts:
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.

CIRCUIT DESCRIPTION
The signals from the RF circuit are mixed with the VCO signals at the 1st mixer circuit (Q1) to produce a 21.7 MHz 1st
IF signal.
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
(MAIN UNIT)
The antenna switching circuit functions as a low-pass filter
while receiving and as resonator circuit while transmitting.
The circuit does not allow transmit signals to enter receiver
circuits.
The 1st IF signal is applied to two crystal filters (FI1, FI2) to
suppress out-of-band signals and is then amplified at the IF
amplifier (Q2). The amplified signal is applied to the 2nd
mixer circuit (IC1).
Received signals enter the MAIN unit from the antenna connector and pass through the low-pass filter (L13, L14,
C106–C109, C111). The signals are then applied to the RF
circuit via the antenna switching circuit (D15, L15, C197,
C198).
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
(MAIN UNIT)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal. A double superheterodyne system (which converts
receive signals twice) improves the image rejection ratio and
obtains stable receiver gain.
4-1-2 RF CIRCUIT (MAIN UNIT)
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals.
The FM IF IC (IC1) contains the 2nd local oscillator, 2nd
mixer, limiter amplifier, quadrature detector, and noise
detector circuits, etc.
The signals from the antenna switching circuit pass through
a tunable bandpass filter (D19, L16, L17, L19, L20,
C199–C204, C206–C210) where the object signals are led
to the RF amplifier circuit (Q27).
The 1st IF signal from Q2 is applied to the 2nd mixer section
of IC1 (pin 16), and is mixed with a 21.25 MHz 2nd LO signal generated at the PLL circuit using the reference frequency (21.25 MHz) to produce a 450 kHz 2nd IF signal.
The amplified signals at Q7 are applied to the 3-stage tunable bandpass filter (D20, L21, L22, L24, L25, C213–C218,
C220–C224) to suppress unwanted signals and improve the
selectivity. The signals are then applied to the 1st mixer circuit.
The 2nd IF signal from IC1 (pin 3) is passed through the
ceramic filter (FI3), where unwanted signals are suppressed, and is then applied to the 2nd IF (limiter) amplifier
in IC1 (pin 5). The signal is applied to the FM detector section in IC1 for demodulation into AF signals.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
(MAIN UNIT)
The FM detector circuit employs a quadrature detection
method (linear phase detection), which uses a ceramic discriminator (X1) for phase delay to obtain a non-adjusting circuit. The detected signal from IC1 (pin 9) is applied to the AF
circuit.
The 1st mixer circuit converts the received signal to a fixed
frequency of the 1st IF signal with a 1st LO (VCO output) frequency. By changing the 1st LO frequency, only the desired
frequency will be passed through two crystal filters at the
next stage of the mixer.

4-1-5 AF AMPLIFIER CIRCUIT
(MAIN AND FRONT UNITS)
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
(MAIN UNIT)
The AF amplifier circuit amplifies the detected signals to
drive a speaker. The AF circuit includes an AF mute circuit
for the squelch.
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis from the microphone to a level
needed at the modulation circuit.
AF signals from IC1 (pin 9) are applied to the de-emphasis
circuit (R101, C140). The de-emphasis circuit is an integrated circuit with frequency characteristic of –6 dB/octave.
The AF signals from the microphone are amplified at the
microphone amplifier (IC7B) via the analog switch (IC4A, pin
1). A capacitor (C159) and resistor (R121) are connected to
the amplifier to obtain the pre-emphasis characteristics.
The integrated signals pass through the high-pass filter
(Q21, R96–R100, C138, C139) to suppress unwanted lower
noise signals.
The amplified signals are applied to the IDC amplifier (IC7C,
pin 9) and are passed through the splatter filter (IC7D) to
suppress unwanted 3 kHz or higher signals. The filtered signals are then applied to the modulation circuit.
The filtered signals are applied to the AF mute circuit (IC5A),
and then passes through the [VOLUME] control (VR-A
board; R1) via the “VOL1” signal. The signals are applied to
the AF power amplifier (IC9, pin 1). The output signal from
IC9 (pin4) drives the internal (external) speaker.
4-2-2 MODULATION CIRCUIT (MAIN UNIT)
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signals.
4-1-6 SQUELCH CIRCUIT
(MAIN UNIT AND LOGIC BOARD)
Audio signals from the splatter filter (IC7D) pass through the
frequency deviation adjustment pot (R138) and are then
applied to the modulation circuit (D2, D3, D4) to change the
reactance of D2, D3, D4 and modulate the oscillated signal
at the VCO (Q5, Q6).
A squelch circuit cuts out AF signals when no RF signals are
received. By detecting noise components in the AF signals,
the squelch circuit switches the AF mute switch.
A portion of the AF signals from the FM IF IC (IC1, pin 9)
pass through the squelch adjustment pot (R16), and are
then applied to the active filter section (IC1, pin 8). The
active filter section amplifies and filters noise components.
The filtered signals are applied to the noise detector section
and output from pin 14 as the “SQL” signal. The “SQL” signal is applied to the CPU (LOGIC board; IC1, pin 90). The
CPU analyzes the noise condition and outputs the “RMUM”,
“RMUTS” signals to toggle the AF mute switches (IC5A,
IC5B).
4-2-3 DRIVE AMPLIFIER CIRCUIT (MAIN UNIT)
The drive amplifier circuit amplifies the VCO oscillating signal to a level needed at the power amplifier.
The VCO output is buffer-amplified by Q7 and Q9, and is
then applied to the Tx/Rx switch (D6). The transmit signal
from the Tx/Rx switch is amplified to the pre-drive (Q10) and
YGR (Q11) amplifiers to obtain an approximate 300 mW signal level. The amplified signal is then applied to the RF
power amplifier (IC3).
4-1-7 WEATHER ALERT DECODER CIRCUIT
(MAIN UNIT AND LOGIC BOARD)
When the weather alert function is activated and a 1050 Hz
alert tone from an NOAA weather radio broadcast is
received, the IC-M402 emits beep tones and indicates flashing “ALT” on the display to inform of an emergency weather
report on the air.
4-2-4 POWER AMPLIFIER CIRCUIT (MAIN UNIT)
The power amplifier circuit amplifies the driver signal to an
output power level.
IC3 is a power module which has amplification output capabilities of about 35 W with 300 mW input. The output from
IC3 (pin 4) is passed through the antenna switching circuit
(D10) and is then applied to the antenna connector via the
low-pass filter.
AF signals from the FM IF IC (IC1, pin 9) pass through the
low-pass filter (Q28) via the “DET” signal, and are then
applied to A/D port of the CPU (LOGIC board; IC1, pin 88)
as “WXDEC” signal. The CPU has the tone decoder function. When a 1050 Hz signal is detected by software decode,
the CPU (LOGIC unit; IC1) controls beep tones and the
“ALT” indicator.

FM IF IC (IC1, pin 9)
The PLL circuit , using a one chip PLL IC (MAIN unit; IC2),
directly generates the transmit frequency and receive 1st IF
frequency with VCOs. The PLL sets the divided ratio based
on serial data from the CPU on the LOGIC unit and compares the phases of VCO signals with the reference oscillator frequency. The PLL IC detects the out-of-step phase and
output from pins 8 for Tx and Rx. The reference frequency
(21.25 MHz) is oscillated at X2 (MAIN unit).
4-2-5 APC CIRCUIT (MAIN UNIT)
The APC circuit stabilizes transmit output power.
The RF output signal from the power amplifier (IC3) is
detected at the power detector circuit (D8, D9, L12) and is
then applied to one of the differential amplifier inputs (Q15,
pin 5) via the High/Low control circuit (R71, Q16). The
applied voltage controls the differential amplifier output
(Q15, pin 2) and the bias voltage control (Q12). Thus the
APC circuit maintains a constant output power.
4-3-2 TX AND RX LOOP (MAIN UNIT)
The generated signal at the VCO (Q4, Q5, Q6, D1–D4)
enters the PLL IC (IC2, pin 2) and is divided at the programmable divider section and is then applied to the phase
detector section.
4-3 PLL CIRCUITS
4-3-1 GENERAL
The PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL circuit compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by a
crystal oscillator and the divided ratio of the programmable
divider.
The phase detector compares the input signal with a reference frequency, and then outputs the out-of-phase signal
(pulse-type signal) from pin 8.
The pulse-type signal is converted into DC voltage (lock
voltage) at the loop filter (R29–R31, R41, C41, C42, C50,
C51), and is then applied to varactor diodes (D3, D4) of the
VCO to stabilize the oscillated frequency. The lock voltage
from the loop filter is amplified at the buffer amplifier (Q7)
and then applied to the RF circuit.
IC2 on the MAIN unit is a dual PLL IC which controls both
VCO circuits for Tx and Rx, and contains a prescaler, programmable counter, programmable divider, phase detector,
charge pump, etc.

4-6 POWER SUPPLY CIRCUITS
The VCO outputs from Q4–Q6 are buffer-amplified at the

switch (D5 and D6). The receive LO signal is applied to the
1st mixer circuit (Q1) through a low-pass filter, and the transmit signal is applied to the pre-drive amplifier (Q10). A portion of the VCO output is reapplied to the PLL IC (IC2, pin 2)
