ORDERING PARTS REPAIR NOTES
This service manual describes the latest service information
for the IC-M302 VHF MARINE TRANSCEIVER at the time of
publication.
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than 16 V. Such a connection
could cause a fire or electric hazard.
DO NOT expose the transceiver to rain, snow or any liquids.
DO NOT reverse the polarities of the power supply when con-
necting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100mW)
to the antenna connector. This could damage the trans-
ceiver's front end.
Be sure to include the following four points when ordering
replacement parts:
1. 10-digit order numbers
2. Component part number and name
3. Equipment model name and unit name
4. Quantity required

1. Make sure a problem is internal before disassembling the
transceiver.
2. DO NOT open the transceiver until the transceiver is dis-
connected 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 insulat-
ed turning tool MUST be used for all adjustments.
5. DO NOT keep power ON for a long time when the trans-
ceiver is defective.
6. DO NOT transmit power into a signal generator or a
sweep generator.
7. ALWAYS connect a 30 dB to 40 dB attenuator between
the transceiver and a deviation meter or spectrum ana-
lyzer when using such test equipment.
8. READ the instructions of test equipment thoroughly
before connecting equipment to the transceiver.
To upgrade quality, all electrical or mechanical parts and
internal circuits are subject to change without notice or oblig-
ation.

SECTION 4 CIRCUIT DESCRIPTION
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.
Received signals enter the MAIN unit from the antenna con-
nector and pass through the low-pass filter (L1, L2, C3–C5).
The signals are then applied to the RF circuit via the anten-
na switching circuit (D2).
4-1-2 RF CIRCUIT (MAIN UNIT)
The RF circuit amplifies signals within the range of frequen-
cy coverage and filters out-of-band signals.
The signals from the antenna switching circuit pass through
the *attenuator (R2, C9) and a tunable bandpass filter (D4,
L6, C12–C15) where the object signals are led to the RF
amplifier circuit (Q1).
(*Passing through the attenuator is [#10] ONLY.)
The amplified signals at Q1 are applied to other tunable
bandpass filter (D5–D7, L8, L9, C23–C26, C28–C32) to sup-
press unwanted signals and improve the selectivity. The sig-
nals are then applied to the 1st mixer circuit.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
(MAIN UNIT)
The 1st mixer circuit converts the received signal to a fixed
frequency of the 1st IF signal with a 1st LO (VCO output) fre-
quency. By changing the 1st LO frequency, only the desired
frequency will be passed through two crystal filters at the
next stage of the mixer.
The signals from the RF circuit are mixed with the VCO sig-
nals at the 1st mixer circuit (Q2) to produce a 21.7 MHz 1st
IF signal.
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 (Q4). The amplified signal is applied to the 2nd
mixer circuit (IC1).
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.
The FM IF IC (IC1) contains the 2nd local oscillator, 2nd
mixer, limiter amplifier, quadrature detector, and noise
detector circuits, etc.
The 1st IF signal from Q4 is applied to the 2nd mixer section
of IC1 (pin 16), and is mixed with a 21.25 MHz 2nd LO sig-
nal generated at the PLL circuit using the reference fre-
quency (21.25 MHz) to produce a 450 kHz 2nd IF signal.
The 2nd IF signal from IC1 (pin 3) is passed through the
ceramic filter (FI3), where unwanted signals are sup-
pressed, and is then applied to the 2nd IF (limiter) amplifier
in IC1 (pin 5). The signal is applied to the FM detector sec-
tion in IC1 for demodulation into AF signals.
The FM detector circuit employs a quadrature detection
method (linear phase detection), which uses a ceramic dis-
criminator (X1) for phase delay to obtain a non-adjusting cir-
cuit. The detected signal from IC1 (pin 9) is applied to theAF
circuit.

4-1-5 AF AMPLIFIER CIRCUIT
(MAIN AND FRONT UNITS)
The AF amplifier circuit amplifies the detected signals to
drive a speaker. The AF circuit includes an AF mute circuit
for the squelch.
AF signals from IC1 (pin 9) are applied to the de-emphasis
circuit (R61, C89). The de-emphasis circuit is an integrated
circuit with frequency characteristic of –6 dB/octave.
The integrated signals pass through the high-pass filter (Q5,
R62–R67, C90, C91) to suppress unwanted lower noise sig-
nals.
The filtered signals are applied to theAF mute circuit (IC7B),
and then passes through the [VOLUME] control (VR board;
R1) via the “VOL1”signal. The signals are applied to the AF
power amplifier (IC6, pin 1). The output signal from IC6
(pin4) drives the internal (external) speaker.
4-1-6 SQUELCH CIRCUIT
(MAIN UNIT, LOGIC AND SQL BOARDS)
Asquelch 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 volume (SQL board;
R1), and are then applied to the active filter section (IC1, pin
8). The active filter section amplifies and filters noise com-
ponents. The filtered signals are applied to the noise detec-
tor section and output from pin 14 as the “SQL”signal. The
“SQL”signal is applied to the CPU (LOGIC board; IC1, pin
30). The CPU analyzes the noise condition and outputs the
“RMUTE”signal to toggle the AF mute switches (IC7B).
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-M302 emits beep tones and indicates flash-
ing “ALT”on the display to inform of an emergency weather
report on the air.
AF signals from the FM IF IC (IC1, pin 9) pass through the
low-pass filter (IC2A) via the “DET”signal, and are then
applied to A/D port of the CPU (LOGIC board; IC1, pin 8) as
“WXDEC”signal. The CPU has the tone decoder function.
When a 1050 Hz signal is detected by software decode, the
CPU (LOGIC BOARD; IC1) controls beep tones and the
“ALT”indicator.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
(MAIN UNIT)
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis from the microphone to a level
needed at the modulation circuit.
The AF signals from the microphone are amplified at the
microphone amplifier (IC2B) via the analog switch (IC7A,
pins 1, 2). A capacitor (C223) and resistor (R167) are con-
nected to the amplifier to obtain the pre-emphasis charac-
teristics.
The amplified signals are applied to the IDC amplifier (IC2C,
pin 9) and are passed through the splatter filter (IC2D, pins
12, 14) to suppress unwanted 3 kHz or higher signals. The
filtered signals are then applied to the modulation circuit.
4-2-2 MODULATION CIRCUIT (MAIN UNIT)
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signals.
Audio signals from the splatter filter (IC2D) pass through the
frequency deviation adjustment pot (R184) and are then
applied to the modulation circuit (D11, D12) to change the
reactance of D11–D14 and modulate the oscillated signal at
the VCO (Q13, Q14).
4-2-3 DRIVE AMPLIFIER CIRCUIT (MAIN UNIT)
The drive amplifier circuit amplifies the VCO oscillating sig-
nal to a level needed at the power amplifier.
The VCO output is buffer-amplified by Q15 and Q16, and is
then applied to the Tx/Rx switch (D16, D17). The transmit
signal from the Tx/Rx switch is amplified to the pre-drive
(Q17) and YGR (Q18) amplifiers to obtain an approximate
10 mW signal level. The amplified signal is then applied to
the RF power amplifier (IC4).
4-2-4 POWER AMPLIFIER CIRCUIT (MAIN UNIT)
The power amplifier circuit amplifies the driver signal to an
output power level.
IC4 is a power module which has amplification output capa-
bilities of about 25 W with 10 mW input. The output from IC4
(pin 4) is passed through the antenna switching circuit (D1)
and is then applied to the antenna connector via the low-
pass filter.

4-2-5 APC CIRCUIT (MAIN UNIT)
The APC circuit stabilizes transmit output power.
The RF output signal from the power amplifier (IC4) is
detected at the power detector circuit (D21, D22, L31) and
is then applied to one of the differential amplifier inputs
(Q21, pin 3) via the High/Low control circuit (Q22, R135).
The applied voltage controls the differential amplifier output
(Q21, pin 1) and the bias voltage control (Q23). Thus the
APC circuit maintains a constant output power.
4-3 PLL CIRCUITS
4-3-1 GENERAL (MAIN UNIT)
The PLL circuit provides stable oscillation of the transmit fre-
quency and receive 1st LO frequency. The PLL circuit com-
pares the phase of the divided VCO frequency to the refer-
ence frequency. The PLL output frequency is controlled by a
crystal oscillator and the divided ratio of the programmable
divider.
IC8 on the MAIN unit is a dual PLL IC which controls both
VCO circuits for Tx and Rx, and contains a prescaler, pro-
grammable counter, programmable divider, phase detector,
charge pump, etc.
The PLL circuit , using a one chip PLL IC (MAIN unit; IC8),
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 BOARD 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).
4-3-2 TX AND RX LOOP (MAIN UNIT)
The generated signal at the VCO (Q13, Q14, D11–D14)
enters the PLL IC (IC8, pin 2) and is divided at the pro-
grammable divider section and is then applied to the phase
detector section.
The phase detector compares the input signal with a refer-
ence 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 (R211–R213, C252, C254), and is
then applied to varactor diodes (D13, D14) of the VCO to
stabilize the oscillated frequency.

4-3-4 VCO CIRCUIT (MAIN UNIT)
The VCO outputs from Q13, Q14 are buffer-amplified at the
buffer amplifiers (Q15 and Q16), and are then sent to the
Tx/Rx switch (D16 and D17). The receive LO signal is
applied to the 1st mixer circuit (Q2) through a low-pass filter,
and the transmit signal is applied to the pre-drive amplifier
(Q17).A portion of the VCO output is reapplied to the PLLIC
(IC8, pin 2) via the buffer amplifier (Q26).
4-4 DSC CIRCUITS
4-4-1 DSC ENCODE CIRCUIT
(LOGIC BOARD AND MAIN UNIT)
The DSC signal is created at the CPU (IC1, pin 9). The sig-
nal passes through the buffer amplifier (IC6A, pins 1, 3), and
is then applied to the D/A convertor (R176–R179) to convert
into the analog signal. The analog signal passes through the
low-pass filter (MAIN unit; IC2D, pins 12, 14), and is then
applied to the VCO circuit to modulate the DSC signal.
4-4-2 DSC DECODE CIRCUIT
(MAIN UNIT AND LOGIC BOARD)
The AF signal from the FM IF IC (IC1, pin 9) are filtered at
the low-pass filter (IC2A, pins 1, 3) to suppress unwanted
higher noise signals. The filtered signals are converted ana-
log signals into digital signals at the DSC decoder IC (IC3),
and are then applied to the CPU (LOGIC board; IC1, pin 22)
via the “DSCDEC”signal.
