■Front End (RF AMP)
The signal coming from the antenna passes through the
transmit/receive switching diode circuit, (D103, D104 and
D106) passes through a BPF (L213 and L212), and is ampli-
fied by the RF amplifier (Q204).
The resulting signal passes through a BPF (L209, L207
and L206) and goes to the mixer. These BPFs are non-vari-
able type.
CIRCUIT DESCRIPTION
■First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q203 to pro-
duce a first IF frequency of 38.85MHz.
The resulting signal passes through the XF201 MCF to
cut the adjacent spurious and provide the opitimun charac-
teristics, such as adjacent frequency selectivity.
■IF Amplifier Circuit
The first IF signal is passed through a four-pole monolithic
crystal filter (XF201) to remove the adjacent channel signal.
The filtered first IF signal is amplified by the first IF ampli-
fier (Q202) and then applied to the lF system IC (IC201).
The IF system IC provides a second mixer, limiting amplifier,
quadrature detector and RSSI (Received Signal Strength In-
dicator). The second mixer mixes the first IF signal with the
38.4MHz of the second local oscillator output (TCXO X1 and
Q2) and produces the second IF signal of 450kHz.
The second IF signal is passed through the ceramic filter
(CF201) to remove the adjacent channel signal. The filtered
second IF signal is amplified by the limiting amplifier and
demodulated by the quadrature detector with the ceramic
discriminator (CD201). The demodulated signal is routed to
the audio circuit.
■Audio Amplifier Circuit
The demodulated signal from IC201 goes to AF amplifier
through IC308.
The signal then goes through an AF volume control , and
is routed to an audio power amplifier (IC309) where it is am-
plified and output to the speaker.
■Squelch
Part of the AF signal from the IC enters the FM IC (IC201)
again, and the noise component is amplified and rectified by
a filter and an amplifier to produce a DC voltage correspond-
ing to the noise level.
The DC signal from the FM IC goes to the analog port
of the MCU (IC306). IC306 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, IC306 sends a high
signal to the AF_CONT line and turns IC309 on through
Q312, Q313, Q314, Q315 and Q316. (See Fig. 4)

■Receive Signaling
• QT/DQT
The output signal from FM IC (IC201) enters the MCU
(IC306) through IC308. IC306 determines whether the QT or
DQT matches the preset value, and controls the SP MUTE
and the speaker output sounds according to the squelch re-
sults.
3. PLL Frequency Synthesizer
The PLL circuit generates the first local oscillator signal
for reception and the RF signal for transmission.
■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 an oscillator (VCO) output signal
which is buffer amplified by Q3 then divided in IC1 by a pro-
grammable counter. The divided signal is compared in phase
with the 5 or 6.25kHz reference signal from the phase com-
parator 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. 5)
■VCO
The operating frequency is generated by Q5 in transmit
mode and receive mode. The oscillator frequency is con-
trolled by applying the VCO control voltage, obtained from
the phase comparator, to the varactor diodes (D4 and D8).
The outputs from Q5 is amplified by Q9 and sent to the
RF amplifiers.
■Unlock Detector
If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from C4 and
Q1 causes the voltage applied to the MCU to go low. When
the MCU detects this condition, the transmitter is disabled,
ignoring the push-to-talk switch input signal.

■Drive and Final Amplifier
The signal from the T/R switch (D10 is on) is amplified by
the pre-drive (Q101 and Q102) and the drive amplifier (Q103).
The output of the drive amplifier is amplified by the RF
power amplifier (Q106) to 0.5W. The output of the RF
power amplifier is then passed through the harmonic filter
(LPF) and antenna switch (D103) and applied to the antenna
terminal.

■APC Circuit
The APC circuit always monitors the current flowing
through the drive amplifier and RF power amplifier (Q103
and Q106) and keeps a constant current.
The voltage drop at R120, R123 and R126 is caused by
the current flowing through the RF power amplifier and
drive amplifier, and this voltage is applied to the differential
amplifier IC101 (1/2).
IC101(2/2) compares the output voltage of IC101 (1/2)
with the reference voltage from IC306. The output of IC101

(2/2) controls the VG of the RF power amplifier and drive
amplifier to make both voltages the same.
The change of power high/low is carried out by the
change of the reference voltage.
■Encode Signaling
• QT/DQT
QT/DQT data of the QTTCXO Line is output from pin 14
of the MCU. The signal passes through a low-pass CR filter
and goes to the TCXO (X1).
The QT/DQT data of the QTVCO Line is output from pin
15 of the MCU. The signal passes through a low pass CR fil-
ter, mixes with the audio signal, and goes to the VCO modu-
lation input. TX deviation is adjusted by the MCU.
5. Power Supply
There are four 5V power supplies in the transceiver: 5M,
5C, 5R, and 5T. 5M for MCU is always output while the
power is on. 5M is always output, but turns off when the
power is turned off to prevent malfunction of the MCU.
5C is a common 5V and is output when SAVE is not set
to OFF.
5R is 5V for reception and output during reception.
5T is 5V for transmission and output during transmission.
6. Control Circuit
The control circuit consists of a MCU (IC306) and its
peripheral circuits. It controls the TX-RX unit. IC306 mainly
performs the following:
1) Switching between transmission and reception by the
PTT signal input.
2) Reading system, group, frequency, and program data
from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off by the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit by the decode data in-
put.
6) Transmitting tone and encode data.
■Frequency Shift Circuit
The MCU (IC306) operates at a clock of 14.746 MHz. This
oscillator has a circuit that shifts the frequency by BEAT
SHIFT SW (Q305, Q306).
A beat sound may be able to be evaded from generation
if “Beat Shift” is set to ON when it is generated in the inter-
nal spurious transmission modulated sound of a transceiver.

PROM (IC305). An EEPROM has a capacity of 16k bits that
contains the transceiver control program for the MCU and
data such as transceiver channels and operating features.

■Low Battery Warning
The battery voltage is checked using by the MCU. The
transceiver generates a warning tone when it falls below
the warning voltage shown in the table.
1) The red LED blinks when the battery voltage falls below
the voltage (1) shown in the table during transmission.
Note: The transceiver checks the battery voltage during
reception even when, in the FPU, the Battery Warning
status function is set to “On TX” (default setting).
However, the LED does not blink during reception. Dur-
ing transmission, the LED blinks to generate the warning
tone of a low battery voltage.
2) The transceiver immediately stops transmission when
the battery voltage falls below the voltage (2) shown in
the table. A message tone beeps while the PTT switch is
released.

■Antenna connector adapter
The antenna connector of this transceiver 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.)
■Repair Jig (Chassis)
Use jig (part No.: A10-4125-03) for repairing the transceiv-
er. Place the TX-RX unit on the jig and fit it with screws.
The jig facilitates the voltage check and protects the final
amplifier FET when the voltage on the flow side of the TX-
RX unit is checked during repairs.
■Battery Jig (W05-1011-00)
Connect the power cable properly between the battery
jig installed in the transceiver and the power supply, and
be sure output voltage and the power supply polarity prior
to switching the power supply ON, otherwise over voltage
and reverse connection may damage the transceiver, or the
power supply or both.
Note: When using the battery jig, you must measure the
voltage at the terminals of the battery jig. Otherwise, a
slight voltage drop may occur within the power cable, be-
tween the power supply and the battery jig, especially while
the transceiver transmits.
