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 tuning 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 50 dB to 60 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
4-1 RECEIVER CIRCUITS
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
(MAIN UNIT)
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 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.
Received signals enter the MAIN unit from the antenna
connector and pass through the low-pass filter (L1, L2, C3
–C5). The signals are then applied to the RF circuit via the
antenna switching circuit (D2).
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 signal generated at the PLL circuit using the reference
frequency (21.25 MHz) to produce a 450 kHz 2nd IF signal.
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 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.
The signals from the antenna switching circuit pass through
a tunable bandpass filter (D4, L6, C12–C16) where the
object signals are led to the RF amplifier circuit (Q1).
The amplified signals at Q1, L7–L9 are applied to other
tunable bandpass filter (D5–D7, C22–C26, C29–C34) to
suppress unwanted signals and improve the selectivity. The
signals are then applied to the 1st mixer circuit.
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.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
(MAIN UNIT)
4-1-7 WEATHER ALERT DECODER CIRCUIT
(MAIN UNIT AND LOGIC BOARD)
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.
When the weather alert function is activated and a 1050
Hz alert tone from an NOAA weather radio broadcast is
received, the IC-M304 emits beep tones and indicates
flashing “ALT” on the display to inform of an emergency
weather report on the air.
The signals from the RF circuit are mixed with the VCO
signals at the 1st mixer circuit (Q2) to produce a 21.7 MHz
1st IF signal.
AF signals from the FM IF IC (IC1, pin 9) pass through
the low-pass filter (Q5, R52–R58, C83–C86) 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.
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).

4-1-5 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 (R61, C89). 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 (IC10A) via the analog switch
(IC7A, pins 1, 2). A capacitor (C223) and resistor (R171)
are connected to the amplifier to obtain the pre-emphasis
characteristics.
The integrated signals pass through the Band-pass filter (Q6,
Q7, R62–R70, C90–C94) to suppress unwanted lower noise
signals.
The amplified signals are applied to the IDC amplifier and
are passed through the splatter filter (IC10B, pins 5–7) 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 (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.
4-2-2 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, LOGIC AND SQL BOARDS)
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.
Audio signals from the splatter filter (IC10B) 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).
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
components. The filtered signals are applied to the noise
detector section and output from pin 13 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).
4-2-3 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 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 YGR (Q17)
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
capabilities 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.

4-3 PLL CIRCUITS
4-3-2 TX AND RX LOOP (MAIN UNIT)
4-3-1 GENERAL (MAIN UNIT)
The generated signal at the VCO (Q13, Q14, D11–
D14) enters the PLL IC (IC8, pin 2) and is divided at the
programmable divider section and is then applied to the
phase detector section.
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.
IC8 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.
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.
The PLL circuit , using a one chip PLL IC (MAIN unit; IC8),
directly generates the transmit frequency and receive 1st IF
frequency with VCO. 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).
4-3-4 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 YGR amplifier (Q17).
A portion of the VCO output is reapplied to the PLL IC (IC8,
pin 2) via the buffer amplifier (Q26).

The DSC signal is created at the CPU (IC1, pin 9). The
signal 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; IC10B, pins 5–7),
and is then applied to the VCO circuit to modulate the DSC
signal.
4-4-2 DSC DECODE CIRCUIT
(MAIN UNIT AND LOGIC UNIT)
The AF signal from the FM IF IC (IC1, pin 9) are filtered at
the low-pass filter (Q5, R52–R58, C83–C86) to suppress
unwanted higher noise signals. The filtered signals are
converted analog signals into digital signals at the DSC
decoder IC (IC3), and are then applied to the CPU (LOGIC
UNIT; IC1, pin 22) via the “DSCDEC” signal.
4-5 LOGIC CIRCUITS (LOGIC UNIT)
