REPAIR NOTES

This service manual describes the latest service information

for the IC-M32 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 10 V. This will ruin the

transceiver.

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 transceiv-

er’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

venience.

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, all electrical or mechanical parts and

internal circuits are subject to change without notice or oblig-

ation.

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 from the antenna connector pass through

the low-pass filter (L81, L82, C83–C86, C89) and antenna

switching circuit (D52, D90). The filtered signals are then

applied to the RF amplifier circuit (Q90).

4-1-2 RF AND 1ST MIXER CIRCUITS (MAIN UNIT)

The 1st mixer circuit converts the received signals to a fixed

frequency of the 1st IF signal with a PLL output frequency.

By changing the PLL frequency, only the desired frequency

will be passed through a pair of crystal filters at the next

stage of the 1st mixer.

The signals from the antenna switching circuit are passed

through the tunable bandpass filter (D92) and amplified at

the RF amplifier (Q90). The amplified signals are passed

through another tunable bandpass filter (D130), and then

applied to the 1st mixer circuit (Q150).

The filtered signals are mixed at the 1st mixer (Q150) with a

1st LO signal coming from the PLL circuit to produce a 21.7

MHz 1st IF signal. The 1st IF signal is passed through two

crystal filters (FI150, FI151) and is then amplified at the IF

amplifier (Q151).

4-1-3 2ND IF AND DEMODULATOR CIRCUITS

(MAIN UNIT)

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

and obtain stable receiver gain.

The 1st IF signal is applied to a 2nd mixer section of the FM

IF IC (IC170, pin 16). The signal is then mixed with a 2nd LO

signal for conversion into a 450 kHz 2nd IF signal.

IC170 contains the 2nd mixer, limiter amplifier, quadrature

detector and active filter circuits. A 21.25 MHz 2nd LO signal

is produced at the PLL circuit using the reference frequency.

The 2nd IF signal from the 2nd mixer (IC170, pin 3) passes

through ceramic filters (FI170) to remove unwanted hetero-

dyne frequencies. It is then amplified at the limiter amplifier

section (IC170, pin 5) and applied to the quadrature detec-

tor section (IC170, pins 10 and 11) to demodulate the 2nd IF

signal into AF signals.

4-1-4 AF CIRCUIT (MAIN UNIT)

AF signals from the FM IF IC (IC170, pin 9) are fed to the

analog switch (IC260).

The AF signals (detected signals) are passed through the

analog switch (IC260, pins 2 and 1) and are then applied to

the active low-pass filter (IC200c, pin 9).

The filtered AF signals are applied to and adjusted audio

level at the D/A convertor (IC190, pin 24) to adjust ampli-

tude. The level controlled signals are passed through the AF

mute switch (Q280) which is controlled by “AFMS” signal

from the CPU (IC360, pin 47). The passed signals are

applied to the AF power amplifier (IC280, pin 4), and then

output to the internal speaker or [EXT SP] jack after being

passed through the de-emphasis circuit (R286, C285) to

obtain the –6 dB/octave frequency characteristics.

4-1-5 SQUELCH CIRCUIT (MAIN UNIT)

The noise 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 divided by C175 from the FM IF

IC (IC170, pin 9) are applied to the D/A convertor (IC190, pin

16) to adjust amplitude. The signals from the D/A convertor

(IC190, pin 15) are applied to the active filter section (IC170,

pin 8). The active filter section amplifies and filters noise

components. The filtered signals are applied to the noise

detector section and output from IC170 (pin 14) as the

“NOISV” signal.

The “NOISV” signal from IC170 (pin 14) is applied to the

CPU (IC360, pin 2). The CPU compares the set squelch

level voltage and “NOISV” signal voltage to control the

squelch output.

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 characteristics from the micro-

phone to a level needed for the modulation circuit.

The AF signals from the microphone are passed through the

pre-emphasis circuit (R253, C254) and are then applied to

the microphone amplifier (IC200b). The amplified AF signals

are applied to analog switch (IC260, pin 5).

The AF signals are amplified again at the limiter-amplifier

(IC200a) and then passed through the low-pass filter

(IC200d, pins 12 and 13). The filtered audio is applied to the

RF unit as the “MOD” signal.

4-2-2 MODULATION CIRCUIT (MAIN UNIT)

The modulation circuit modulates the VCO oscillating signal

(RF signal) using the microphone audio signals.

The audio signals “MOD” change the reactance of D20 to

modulate an oscillated signal at the VCO circuit (Q21, Q22,

D22, D23). The oscillated signal is amplified at the buffer-

amplifiers (Q23, Q24).

4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS

(MAIN UNIT)

The signal from the VCO circuit passes through the trans-

mit/receive switching circuit (D50, D51) and is applied to the

buffer-amplifier (Q50). The amplified signal is amplified by

the pre-driver (Q53) and the power amplifier (Q54) to obtain

5 W of RF power (at 7.2 V). The amplified signal passes

through the antenna switching circuit (D52), and low-pass fil-

ter (L81, L82, C83–C86, C89) and is then applied to the

antenna connector.

The bias current of the pre-driver (Q53) and the power

amplifier (Q54) is controlled by the APC circuit to stabilize

the output power.

4-2-4 APC CIRCUIT (MAIN UNIT)

The APC circuit provides stable output power from the

power amplifier even when the input voltage or temperature

changes, and, selects HIGH or LOW output power. The APC

circuit consists of a power detector and APC control circuits.

• POWER DETECTOR CIRCUIT (MAIN UNIT)

The power detector circuit (D80, C87) detects the transmit

output power level and converts it to DC voltage as the

“TDETV” signal. The detected signal is applied to the TX

control circuit.

• APC CONTROL CIRCUIT (MAIN UNIT)

The detected signal from the power detector circuit (D91,

R280) is applied to the CPU (IC360, pin 4) to control the

input voltage of the pre-driver (Q53) and the power amplifi-

er (Q54). When the output power changes, the CPU (IC360)

outputs APC control signal to the D/A converter (IC190). And

then “PCON” signal from the D/A converter controls the APC

controller (IC50) to provide stable output power.

4-3 PLL CIRCUIT (MAIN UNIT)

A PLL circuit provides stable oscillation of the transmit fre-

quency and receive 1st LO frequency. The PLL output com-

pares the phase of the divided VCO frequency to the refer-

ence frequency. The PLL output frequency is controlled by

the divided ratio (N-data) of a programmable divider.

The PLL circuit contains a VCO (Q21, Q22, D22, D23). The

oscillated signal is amplified at the buffer-amplifiers (Q23,

Q25) and then applied to the PLL IC (IC1, pin 19).

The PLL IC contains the prescalers, programmable counter,

programmable divider, phase selector and etc. The entered

signal is divided at the prescaler and programmable counter

sections by the N-data ratio from the CPU. The divided sig-

nal is detected on phase at the phase detector using the ref-

erence frequency.

If the oscillated signal drifts, the phase of its frequency

changes from the reference frequency, causing a lock volt-

age changes to compensate for the drift in the oscillated fre-

quency.

A portion of the VCO signal is amplified at buffer-amplifiers

(Q23, Q24) and is then applied to the receive 1st mixer

(Q150) or transmit driver via the TX/RX switching diode

(D50, D51).
