4. Clone Mode
Programming data can be transferred from one trans-
ceiver to another by connecting them via their SP/MIC con-
nectors.
Cloning can be performed as described below (the trans-
mit transceiver is the source and the receive transceiver is
the target).
The following data cannot be cloned.
• Tuning data
• Model name data
• ESN data
1. Turn the source transceiver and target transceiver power
OFF.
2. Turn the source transceiver power ON while pressing the
[PTT] and [Side] keys, to enter clone mode.
3. Connect the cloning cable (part No. E30-3410-05) to the
SP/MIC connectors on the source and target transceiv-
ers.
4.Turn the target transceiver power ON.
5. Press the [Side] key on the source transceiver.The data of
the source is sent to the target.While the source is send-
ing data, red LED will light. While the target is receiving
the data, green LED will light. When cloning of data is
completed, the source red LED turned off, and the target
automatically operates in the User mode.
6. Additional targets can be continuously cloned. When
the [Side] key on the source is pressed, the data of the
source is sent to the target again. Repeat steps 3 to 5 to
clone additional transceivers.

1. Frequency Configuration
The receiver utilizes double conversion. The first IF is
38.85MHz and the second IF is 450kHz. The first Local os-
cillator is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the neces-
sary frequencies.
2. Receiver System
The receiver system is shown in Figure 2.
2-1. Front End (RF Amplifier) Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D101, D102, D103
and D105) and a BPF (L208 and L210), and is then ampli-
fied by the RF amplifier (Q204).
The resulting signal passes through a BPF (L215, L218
and L219) and goes to the mixer. These BPFs are adjusted
by variable capacitors (D201 D202, and D204). The input
voltage to the variable capacitor is a regulated voltage out-
put from the DAC (IC300)
.

2-2. 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 38.85 MHz.
The resulting signal passes through the XF200 MCF to
cut the adjacent spurious and provide the optimum charac-
teristics, such as adjacent frequency selectivity.
2-3. IF Amplifier Circuit
The first IF signal is passed through a four-pole mono-
lithic crystal filter (XF200) 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 (IC200).
The IF system IC provides a second mixer, second local
oscillator, 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 lo-
cal oscillator output (TCXO X1) and produces the second IF
signal of 450kHz.
The second IF signal is passed through the ceramic filter
(CF200) 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 (CD200).The demodulated signal is routed to
the audio circuit.
2-4. Audio Amplifier Circuit
The demodulated signal from IC200 is amplified by
IC305, IC303 and goes to AF amplifier through IC302.
The signal then goes through an volume control (VR500),
and is routed to an audio power amplifier (IC302) where it is
amplified and output to the speaker.
To output sounds from the speaker, IC400 sends a high
signal to the SPMUT line and turns IC400 on through Q300,
Q301, Q302 and Q306.
3.Transmitter System
3-1. Microphone Amplifier Circuit
The signal from microphone amplified by IC301 and goes
through mute switch (IC300).
IC304 is composed of high-pass filter, low-pass filter and
pre-emphasis/IDC circuit.
The output signal from the DAC IC (IC300) goes to the
VCO modulation input.

3-2. Drive and Final Amplifier Circuit
The signal from the T/R switch (D100 is on) is amplified
by the pre-drive amplifier (Q100) to 30mW.
The output of the pre-drive amplifier is amplified by the
drive amplifier (Q101) and the RF final amplifier (Q102) to
4.0W (1W when the power is low).
The drive amplifier and the RF final amplifier consist of
two MOS FET stages.
The output of the RF final amplifier is then passed
through the harmonic filter (LPF) and antenna switch (D101
and D102) and is applied to the antenna terminal.
4. Frequency Synthesizer Circuit
4-1. Frequency Synthesizer
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL IC (IC1) and buffer amplifiers.
The TCXO generates 19.2MHz.The frequency stability is
2.5 ppm within the temperature range of –30 to +60°C.
The frequency tuning and modulation of the TCXO are
done to apply a voltage to pin 1 of the TCXO. The output of
the TCXO is applied to pin 1 of the PLL IC.
The VCO consists of 1VCO and covers a dual range of
the 350.00~390.00MHz and the 311.15~351.15MHz. The
VCO generates 311.15~351.15MHz for providing to the first
local signal in receive.
The PLL IC consists of a prescaler, reference divider,
phase comparator, charge pump (The frequency step of the
PLL circuit is 5 or 6.25 kHz).
PLL data is output from DATA (pin 19), CLOCK (pin 18)
and PLDL (pin 20) of the MCU (IC400).The data are input to
the PLL IC when the channel is changed or when transmis-
sion is changed to reception and vice versa.A PLL lock con-
dition is always monitored by the pin 22 (PLUL) of the MCU.
When the PLL is unlocked, the PLUL goes low.
3-2. 驱动器和末级放大器电路
来自于 T/R 开关 (D100 ON) 的信号被预驱动放大器 (Q100)
放大到 30mW。
预驱动放大器的输出被驱动放大器 (Q101) 和射频末级放
大器 (Q102) 放大到 4.0W( 当低功率时为 1W)。
驱动放大器和 RF 末级放大器由 2 个 MOS FET 构成。
射频末级放大器的输出通过谐波滤波器 (LPF) 和天线开关
(D101 和 D102) 并且送到天线终端。
4. 频率合成器电路
4-1. 频率合成器
频率合成器由 TCXO(X1)、VCO、PLL IC(IC1) 和缓冲放大
器组成。
TCXO 产生 19.2MHz 的频率。在温度为 -30 ～ +60℃的范围内，
频率的稳定性为 2.5ppm。
进行频率调谐和 TCXO 调制，以便给 TCXO 的针脚 1 提供电压。
TCXO 的输出加在 PLL IC 的针脚 1 上。
VCO 由 1VCO 组成，并且覆盖了 350.00 ～ 390.00M Hz 和
311.15 ～ 351.15M Hz 双 波 段。VC O 产 生 311.15 ～ 351.15M H
的频率，以提供接收的第一个本振信号。
PLL IC 由预计数器、基准除法器、相位比较器、电荷泵组
成 (PLL 电路的频率步长为 5kHz 或 6.25kHz)。
PLL 数据从 MCU(IC400) 的 DATA( 针脚 19)，CLOCK( 针脚
18) 和 PLDL( 针脚 20) 输出。当信道改变时，或当由发射变为
接收或由接收变为发射时，数据输入 PLL IC。PLL 的锁定条
件总是由 MCU 的针脚 22(PLUL) 监控。当 PLL 失锁时，PLUL 为
低电位。

5. Control Circuit
The control consists of the MCU (IC400) and its peripher-
al circuits. It controls the TX-RX unit. IC400 mainly performs
the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading channel information, frequency, and program
data from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off via the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit via the decode data in-
put.
6) Transmitting tone and encode data.
Note:
The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.

and TCXO (X1) modulation input after signal processing in
the DAC IC (IC300).
■High-speed data (DTMF)
High-speed data (HSD) is output from pin 50 (HSDO) of
the MCU.

tion making an adjustment by MCU is applied to the DAC IC
(IC300). The signal is mixed with the audio signal and goes
to the VCO and TCXO.

5M is always output while the power is on.
5C is a common 5V and is output when SAVE is not set
to ON.
5R is 5V for reception and output during reception.
5T is 5V for transmission and output during transmission.
5MS is 5V for the SP/MIC connector and the DAC IC
(IC300).
