REALIGNMENT
4-3. Operation
1. To switch the clone target/s to wireless clone mode,
press and hold the [PTT] and [side2] keys while turning
the transceiver power ON.
2. Wait for 2 seconds. The LED will light orange and the
transceiver will announce “Clone”.
3. Select a channel table number using Side1 (increment
channel table) and Side2 (decrement channnel table)
keys.
4. To switch the clone source to wireless clone mode, press
and hold the [PTT] and [side2] keys while turning the
transceiver power ON.
5. Wait for 2 seconds. The LED will light orange and the
transceiver will announce “Clone”.
6. Select the same channel table number as the clone
target/s.
7. Press [PTT] on the clone source to begin data transmission.
When the clone target starts to receive data, the LED will
light green.
When the clone source finishes sending data, a “confirmation” tone will sound.
If data transmission fails while cloning, an “error” tone
will sound from the target unit.
8. If the cloning fails, no data will be available in the target
unit when it is returned to User mode.
9. When the cloning is successful, the target unit’s “Scan”
and “Key lock” functions will return to their default values
(Scan = OFF, Key lock = OFF).
Notes:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers wireless clone mode is configured as
“Disabled”, the transceiver cannot enter wireless clone
mode.
• The table shown below will cover the frequency tables
used for wireless cloning.
• Wireless clone mode cannot be entered in battery low
state.
• A unit cannot be a “Source Unit” if it is unprogrammed. If
[PTT] is pressed, an “error” tone will sound.
• The language used in cloning depends on the “Model
type” setting, not the FPU setting.
• Once a unit is set to be the source, it cannot be a target
after the data has been transmitted. This protects the
data in the source unit.
• Electronic interface may cause a failure in data transfer
during wireless clone, such as when waveforms or electromagnetics are being performed at the workbench.
• Wireless clone mode can be used ONLY by the authorized service personnel.
• The wireless clone mode setting must be configured
as “Disable” before being delivered to the end-user.
• To clone, replace the antenna from both the source
transceiver and the target transceiver with a dummy
load.
• The transmit output power is automatically set to
Low in wireless clone mode.

CIRCUIT DESCRIPTION
1. Frequency Configuration
The receiver utilizes double conversion. The first IF is
38.85MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the necessary frequencies. Fig. 1 shows the frequencies.
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 adjusted
by variable capacitors (D201, D202, D203, D204 and D205).
The input voltage to the variable capacitor is regulated by
voltage output from the MCU (IC306).

2. Receiver
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q203 to produce a first IF frequency of 38.85MHz.
The resulting signal passes through the XF201 MCF to
cut the adjacent spurious and provide the opitimun characteristics, 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 amplifier (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 Indicator). 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.

CIRCUIT DESCRIPTION
■ Audio Amplifier Circuit
3. PLL Frequency Synthesizer
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 amplified 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 corresponding 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)

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 programmable counter. The divided signal is compared in phase
with the 5 or 6.25kHz reference signal from 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. 5)
■ VCO
The operating frequency is generated by Q5 in transmit
mode and Q4 in receive mode. The oscillator frequency is
controlled by applying the VCO control voltage, obtained
from the phase comparator, to the varactor diodes (D4 and
D8 in transmit mode and D3 and D6 in receive mode).
The RX_SW pin is set high in receive mode causing Q7
turn on. The TX_SW pin is set high in transmit mode. The
outputs from Q4 and Q5 are 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.

The signal from the T/R switch (D10 is on) is amplified by
the pre-drive (Q101 and Q102) and the drive amplifier (Q103)
to 500mW.
The output of the drive amplifier is amplified by the RF
power amplifier (Q106) to 4.0W (1W when the power is
low). 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.

■ 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 filter, mixes with the audio signal, and goes to the VCO modulation input. TX deviation is adjusted by the MCU.
VCO
IC308
AQUA-L
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.
VDD
• MSK (Fleet Sync)
Fleet Sync utilizes 1200bps and 2400bps MSK signal is
output from pin 6 of IC308. And is routed to the VCO. When
encoding MSK, the microphone input signal is muted.
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.

Drive and final amplifier and APC circuit
■ 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).
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 input.
6) Transmitting tone and encode data.

CIRCUIT DESCRIPTION
■ Frequency Shift Circuit
R301
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 internal spurious transmission modulated sound of a transceiver.

■ Memory Circuit
Memory circuit consists of the MCU (IC306) and an EEPROM (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. During 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.)
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, between the power supply and the battery jig, especially while
the transceiver transmits.
+ Terminal (Red)
■ Repair Jig (Chassis)
Use jig (part No.: A10-4215-03) for repairing the transceiver. 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 TXRX unit is checked during repairs.

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.

Preparations for Tuning the Transceiver
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.
