5. Clone Mode
5-1. Outline
“Clone Mode” copies the transceiver data to another
transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.
5-2. Example
The transceiver can copy the programming data to one
or more transceivers via RF communication.
The clone source and clone target/s must be in Clone
mode.
5-3. Operation
1. To switch the clone target/s to Clone mode, press and
hold the [PTT] and [Side2] keys while turning the trans-
ceiver 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 Lock (increment
channel table) and Scan(decrement channnel table) keys.
4. To switch the clone source to Clone mode, press and
hold the [PTT] and [Side2] keys while turning the trans-
ceiver 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 tar-
get/s.
7. Press [PTT] on the clone source to begin data transmis-
sion.
When the clone target starts to receive data, the LED
will light green.
When the clone source finishes sending data, a “confir-
mation” 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”
function will return to their default values (Scan = OFF).
Notes:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers Clone Mode is configured as “Dis-
abled”, the transceiver cannot enter Clone mode.
• The table shown below will cover the frequency tables
used for wireless cloning.
• 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.
• 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.
• If the target unit is cloned successfully, it will return to
User Mode.
• If the target unit is not cloned successfully, the led will
remain Orange.

■Front End (RF AMP)
The signal coming from the antenna passes through the
transmit/receive switching diode circuit, (D103, D104,
D106 and D122) passes through a BPF (L229 and L228), and
is amplified by the RF amplifier (Q205).
The resulting signal passes through a BPF (L214, L212
and L211) and goes to the mixer (Q204). These BPFs are
adjusted by variable capacitors (D203, D204, D205, D206
and D210). The input voltage to the variable capacitor is reg-
ulated by voltage output from the micro control unit (MCU)
(IC405).
■First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q3 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 mono-
lithic crystal filter (XF201) to remove the adjacent channel
signal.
The filtered first IF signal is amplified by the first IF ampli-
fier (Q203) and then applied to the lF system IC (IC201). The
IF system IC provides a second mixer, second local oscilla-
tor, 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 (Q1) 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 IC301.
The signal then goes through an AF volume control, and
is routed to an audio power amplifier (IC302) 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 (IC405). IC405 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, IC405 sends a high
signal to the SP MUTE line and turns IC302 on through
Q303, Q304, Q305, Q306 and Q316. (See Fig. 3)

■Receive Signaling
• QT/DQT
The output signal from FM IC (IC201) enters the MCU
(IC405) through IC301. IC405 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 an oscillator signal is divided at IC1
by a fixed counter to produce oscillator (VCO) output signal
which is buffer amplified by Q2 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. 4)
■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 (D2, D4,
D6 and D7 in transmit mode and D3, D5, D8 and D9 in re-
ceive mode). The RX pin is set high in receive mode causing
Q5 turn on.
The TX pin is set high in transmit mode. The outputs
from Q3 and Q4 are amplified by Q6 and sent to the RF am-
plifiers.

■Unlock Detector
If a pulse signal appears at the LD pin of IC1, an unlock
condition occurs, and the DC voltage obtained from C4, R5,
and D1 causes the voltage applied to the MCU (IC405) to go
low. When the MCU detects this condition, the transmitter
is disabled, ignoring the push-to-talk switch input signal.
4. Transmitter System

The signal from the microphone passes through IC301.
The signal passes through the Audio processor (IC301)
for the maximum deviation adjustment, and goes to the

■Drive and Final Amplifier
The signal from the T/R switch (D101) is amplified by the
pre-drive (Q101) to 50mW.
The output of the drive amplifier is amplified by the RF
power amplifier (Q102 and Q103) to 2W (1W when the
power is low). The RF power amplifier consists of two MOS
FET stages. The output of the RF power amplifier is then
passed through the harmonic filter (LPF) and antenna switch
(D103 and D122) and applied to the antenna terminal.

■APC Circuit
The APC circuit always monitors the current flow-
ing through the RF power amplifier (Q102 and Q103) and
keeps a constant current. The voltage drop at R127, R128
and R129 is caused by the current flowing through the RF
power amplifier and this voltage is applied to the differential
amplifier IC101 (1/2).
CIRCUIT DESCRIPTION

TK-361SA
10
IC101 (2/2) compares the output voltage of IC101 (1/2)
with the reference voltage from MCU (IC405). The output of
IC101 (2/2) controls the VG of the RF power amplifier, Drive
amplifier and Pre-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 28
of the MCU (IC405). 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
24 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 5M, 5C, 5R, and 5T.
5M for MCU (IC405) 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 (IC405) and its
peripheral circuits. It controls the TX-RX unit. IC405 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-

■Frequency Shift Circuit
The MCU (IC405) operates at a clock of 7.3728MHz. This
oscillator has a circuit that shifts the frequency by BEAT
SHIFT SW (Q407, Q408).
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.

■Memory Circuit
Memory circuit consists of the MCU (IC405) and an EE-
PROM (IC406). An EEPROM has a capacity of 64k 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 by the MCU (IC405).
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 recep-
tion 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.
