CLONE MODE
Programming data can be transferred from one trans-
ceiver to another by connecting them via their SP/MIC con-
nectors.
Cloning can copy the transceiver data to another trans-
ceiver even without the use of a personal computer.
The following data cannot be cloned.
• Tuning data
1. Connect the cloning cable (part No. E30-3410-05) to the
SP/MIC connectors on the source and target transceivers.
2. Turn the source and target transceiver power OFF.
3. Turn the source transceiver power ON while pressing the
[CALL] keys, to enter clone mode. ”CLONE” appears on
the display.
4. Turn the target transceiver power ON.
5. Press the [CALL] key on the source transceiver while
”SEND” is displayed.
The data of the source is sent to the target.
While the target is receiving data, ”RECV” appears on the
display.
When cloning is completed, the ”END” appears on the
source and target display.
6. Turn the source and target transceiver power OFF.
Note:
• The Model name and Market codes must be the same in
order to clone the transceiver.
• If a data transfer error occurs during Clone mode, ”ER-
ROR” appears on the target transceiver.
When you turn the target transceiver power ON again
while ”ERROR” is displayed, the target transceiver per-
forms a full reset. At this time, the source transceiver con-
tinues to send data.

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.
Fig. 1 Frequency configuration
Fig. 2 Receiver system
2. Receiver System
The receiver system is shown in Figure 2.
2-1. RF Amplifier Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D101, D102, D103
and D104) and a BPF (L212, L213), and is then amplified by
the RF amplifier (Q204).
The resulting signal passes through a BPF (L209, L210,
L211 and L217) and goes to the mixer. These BPFs are ad-
justed by variable capacitors (D200, D201, D202, D203 and
D204). The input voltage to the variable capacitor is a regu-
lated voltage output 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.

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.
Fig. 3 Microphone amplifier circuit
3-2. Driver and Final Amplifier Circuit
The signal from the T/R switch (D8 is on) is amplified by
the pre-drive amplifier (Q101) to 30mW.
The output of the pre-drive amplifier is amplified by the
drive amplifier (Q102) and the RF final amplifier (Q103) to
5.0W (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.

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
IC303, IC302 and goes to AF amplifier through IC307.
The signal then goes through a volume control (VR300),
and is routed to an audio power amplifier (IC307) where it is
amplified and output to the speaker.
To output sounds from the speaker, IC401 sends a high
signal to the SPMUT line and turns IC401 on through Q301,
Q302, Q303, Q305 and Q306.

CIRCUIT DESCRIPTION
Realign the transceiver after replacing the EEPROM.
6. Signaling Circuit
6-1. Encode
■CTCSS/ DCS
The CTCSS and DCS signals are output from pin 49
(LSDO) of the MCU (IC401). The signal passes through a
low-pass CR filter. The signal is mixed with the audio signal
and goes to the VCO and TCXO (X1) modulation input after
signal processing in the DAC IC (IC300).
■DTMF
The DTMF signal is output from pin 50 (HSDO) of the
MCU.
The signal passes through a low-pass CR filter. TX devia-
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.
6-2. Decode
■CTCSS/DCS
The output signal from IF IC (IC200) enters the MCU
(IC401) through IC300. IC401 determines whether the
CTCSS or DCS matches the preset value, and controls the
SPMUT and the speaker output sounds according to the
squelch results.
Fig. 6 Encode
7. Power Supply
There are five 5V power supplies for the MCU:
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).
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
5.0 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 400.00~469.995MHz and the 361.150~431.145MHz.
The VCO generates 361.150~431.145MHz 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 DAT (pin 19), CLK (pin 18) and
PLDL (pin 20) of the MCU (IC401). The data are input to the
PLL IC when the channel is changed or when transmission
is changed to reception and vice versa. A PLL lock condition
is always monitored by the pin 22 (PLUL) of the MCU. When
the PLL is unlocked, the PLUL goes low.
Fig. 5 PLL block diagram
5. Control Circuit
The control consists of the MCU (IC401) and its peripher-
al circuits. It controls the TX-RX unit. IC401 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.
7) Sending display data to the LCD assembly.
Note:
The EEPROM stores tuning data (Deviation, Squelch,
etc.).

ADJUSTMENT
Note:
• When performing the TH-K40 adjustment, a personal
computer, programming interface cable (PG-4Y, KPG-
22A/22U), tuning cable (E30-3216-05) and tuning software
(MCP-5T) are required.
• When you do not want to lose data such as memory
channels or menu items, save the data using the MCP-
5A (Memory control program), then write the data to the
transceiver after performing the adjustment.
To download the MCP-5A software, go to:
http://www.kenwood.com/i/products/info/amateur/software_download.html
