CIRCUIT DESCRIPTION
The PLL circuit in the transmitter generates the necessary frequencies. Fig. 1 shows the frequencies.
1. Frequency Configuration
The receiver utilizes double conversion. The first IF is

2. Receiver
The receiver is double conversion superheterodyne, designed to operate in the frequency range of 150 to 174MHz.
The frequency configuration is shown in Fig. 1.
1) Front-end RF Amplifier
An incoming signal from the antenna is applied to an RF
amplifier (Q203) after passing through a transmit/receive
switch circuit (D102 and D103 are off) and a band pass filter
(L208, L209 and L210). After the signal is amplified (Q203),
the signal is filtered through a band pass filter (L203 and
L214) to eliminate unwanted signals before it is passed to
the first mixer. Band pass filters (L208, L209, L210, L203
and L214) have varactor diodes (D203, D204, D205, D202
and D201).
The voltage of these diodes are controlled by to track the
MPU (IC403) center frequency of the band pass filter. (See
Fig. 2)

2) First Mixer
The signal from the RF amplifier is heterodyned with the
first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer (Q202) to create a 38.85MHz
first intermediate frequency (1st IF) signal. The first IF signal
is then fed through two monolithic crystal filters (MCFs :
XF200) to further remove spurious signals.
3) IF Amplifier
The first IF signal is amplified by Q201, and then enters
IC200 (FM processing IC). The signal is heterodyned again
with a second local oscillator signal within IC200 to create
a 450kHz second IF signal. The second IF signal is then fed

through a 450kHz ceramic filter (CF200) to further eliminate
unwanted signals before it is amplified and FM detected in
IC200.
4) AF Amplifier
The recovered AF signal obtained from IC200 is amplified
by IC300 (1/4), filtered by the IC300 low-pass filter (2/4) and
IC300 high-pass filter (3/4) and (4/4), and de-emphasized
by R303 and C306. The AF signal is then passed through a
WIDE/NARROW switch (Q303). The processed AF signal
passes through an AF volume control and is amplified to a
sufficient level to drive a loud speaker by an AF power amplifier (IC302).

the microprocessor (IC403). IC403 determines whether to
output sounds from the speaker by checking whether the
input voltage is higher or lower than the preset value.
To output sounds from the speaker, IC403 sends a high
signal to the MUTE and AFCO Iines and turns IC302 on
through Q302, Q304, Q305, Q306 and Q307.(See Fig. 3)
5) Squelch
Part of the AF signal from the IC enters the FM IC again,
and the noise component is amplified and rectified by a filter
and an amplifier to produce a DC voltage corresponding to
the noise level.

6) Receive Signaling
QT/DQT
300 Hz and higher audio frequencies of the output signal
from IF IC are cut by a low-pass filter (IC301). The resulting
signal enters the microprocessor (IC403). IC403 determines
whether the QT or DQT matches the preset value, and controls the MUTE and AFCO and the speaker output sounds
according to the squelch results.
3. PLL Frequency Synthesizer
The PLL circuit generates the first local oscillator signal
for reception and the RF signal for transmission.
1) PLL
The frequency step of the PLL circuit is 5 or 6.25kHz.
A 12.8MHz reference oscillator signal is divided at IC1 by
a fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal
is buffer amplified by Q6, then divided in IC1 by a dual-module programmable counter . The divided signal is compared
in phase with the 5 or 6.25kHz reference signal in the phase
comparator in IC1. The output signal from the phase comparator is filtered through a low-pass filter and passed to the
VCO to control the oscillator frequency. (See Fig.4)

D2 in transmit mode and D3 and D4 in receive mode). The
T/R pin is set high in receive mode causing Q5 and Q7 to
turn Q4 off, and turn Q3 on . The T/R pin is set low in transmit mode. The outputs from Q3 and Q4 are amplified by Q6
and sent to the buffer amplifiers.
2) VCO
The operating frequency is generated by Q4 in transmit
mode and Q3 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained
from the phase comparator, to the varactor diodes (D1 and

3) Unlock Detector
If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from D7, R1,
and C1 causes the voltage applied to the UL pin of the microprocessor to go low. When the microprocessor detects
this condition, the transmitter is disabled, ignoring the pushto-talk switch input signal. (See Fig.5)

4. Transmitter
1) Transmit Audio
2) QT/DQT Encoder
The modulation signal from the microphone is amplified
by IC500 (1/2), passes through a pre-emphasis circuit, and
amplified by the other IC500 (1/2) to perform IDC operation.
The signal then passes through a low-pass filter (splatter
fiIter) (Q501 and Q502) and cuts 3kHz and higher frequencies. The resulting signal goes to the VCO through the VCO
modulation terminal for direct FM modulation. (See Fig. 6)
A necessary signal for QT/DQT encoding is generated by
IC403 and FM-modulated to the PLL reference signal. Since
the reference OSC does not modulate the loop characteristic frequency or higher, modulation is performed at the VCO
side by adjusting the balance. (See Fig. 6)

CIRCUIT DESCRIPTION
3) VCO and RF Amplifier
4) ANT Switch and LPF
The transmit signal obtained from the VCO buffer amplifier Q100, is amplified by Q101. This amplified signal is
passed to the power amplifier, Q102 and Q105, which consists of a 2-stage FET amplifier and is capable of producing
up to 5W of RF power. (See Fig.7)
The RF amplifier output signal is passed through a lowpass filter network and a transmit/receive switching circuit
before it is passed to the antenna terminal. The transmit/
receive switching circuit is comprised of D101, D102, D103
and D104. D102 and D103 turned on (conductive) in transmit mode and off (isolated) in receive mode.

5) APC
The automatic power control (APC) circuit stabilizes the
transmitter output power at a predetermined level by sensing the drain current of the final amplifier Field Effect Transistor (FET) . The voltage comparator, IC100 (2/2), compares
the voltage obtained from the above drain current with a
reference voltage which is set using the microprocessor.
An APC voltage proportional to the difference between the
sensed voltage and the reference voltage appears at the
output of IC100 (1/2). This output voltage controls the gate
of the FET power amplifier, which keeps the transmitter
output power constant. The transmitter output power can
be varied by the microprocessor which in turn changes the
reference voltage and hence, the output power.
APC system
5. Power Supply
A 5V reference power supply [5M] for the control circuit
is derived from an internal battery. This reference is used
to provide a 5V supply in transmit mode [5T], a 5V supply in
receive mode [5R], and a 5V supply common in both modes
[5C] based on the control signal sent from the microprocessor.
6. Control System
The IC403 MPU operates at 7.37MHz . This oscillator has
a circuit that shifts the frequency according to the EEPROM
data.
6) Thermal Protection Circuit
When the thermistor (TH100) reaches about 80˚C, the
protection circuit turns on Q107 to protect transmitting final
amplifier (Q105) from the over heating.

The following parts are required for adjustment
Coaxial antenna connector
1. Antenna connector adapter
The antenna connector of this radio uses an SMA terminal.
Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided
as an option, so buy a commercially-available one.)
2. Jig (chassis) for adjustment(part number A10-1392-03)
■ Use the jig as follows:
1. Insert the coaxial antenna connector into the jig.

Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is tuned, the unit must be connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with
a 8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.

Modulate the AF level with a frequency of 1kHz and deviation
of 1.5kHz (Narrow), 3kHz (Wide). Then take the signal from the
signal generator output when set to -53dBm and obtain the
level shown on an AF VTVM when the AF output has been adjusted to 0.63Vrms with the AF vol.
