2-1. Preface
The transceiver is programmed by using a personal computer, a programming interface (KPG-22/22A, USB adapter
(KCT-53U)) and programming software (KPG-108D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
2-2. Connection Procedure
1. Connect the transceiver to the personal computer with
the interface cable and USB adapter (when the interface
The KPG-22/22A is required to interface the transceiver
with the computer. It has a circuit in its D-sub connector
(KPG-22: 25-pin, KPG-22A: 9-pin) case that converts the RS232C logic level to the TTL level.
The KPG-22/22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.

2-6. Programming with IBM PC
If data is transferred to the transceiver from an IBM PC
with the KPG-108D, the data for each set can be modifi ed.
Data can be programmed into the EEPROM in RS-232C
format via the SP/MIC jack.
In this mode the PTT line operate as TXD and RXD data

• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceiver’s Clone Mode is configured as
”Disabled”, the transceiver cannot enter Clone mode.
• The table shown below will cover the frequencies used
for wireless cloning.
• 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 unsuccessfully, ”error” tone
will sound with ”
• After 4 seconds, Target unit returns to display ”
”xx” means the last selected channel table number.
• The Source unit and Target unit must be of the same
model type and destination in order for Clone to operate.
• It is not possible to read/write setup data from the clone
source/target when it is in Clone mode. But it will trigger
to go to cloning mode (TX) when try to read/write.
• Electronic interface may cause a failure in data transfer
during Wireless Clone, such as when waveforms or electromagnetics are being performed at the workbench.
• Clone mode can be used ONLY by the authorized service
personnel.
• The Clone mode setting must be confi gured as ”Disable”
before being delivered to the end-user.
• When wireless Clone mode is used, the environment
must ensure that the radio wave does not leak to outside.
• The transmit output power is automatically set to Low in
Clone mode.
• Battery saver function is automatically set to off in Clone
mode.

Receiver System
Front End
■
The high-frequency signal from the antenna passes
through a low-pass fi lter and a high-frequency switch (D101,
D200, D201 and L220) which switches between transmission and reception, and goes to the BPF (L218) to remove
unwanted signals. The resulting signal is amplifi ed by highfrequency amplifi er (Q204) and goes to the fi rst mixer (Q203).
First Mixer
■
The signal that reaches Q203 is mixed with the fi rst local
signal from the VCO to produce a fi rst IF signal (38.85MHz).
(Receive frequency – First local frequency
= First IF frequency = 38.85MHz)
The fi rst IF signal passes through MCF: XF200 (monolithic
crystal fi lter) to remove unwanted signals.
The fi rst IF signal is amplifi ed by IF amplifi er (Q201) and
goes to IF IC (IC200).

消除不需要的信号。最终的信号由高频放大器 (Q204) 进行放
大,然后进入第一混频器 (Q203)。
The IF circuit is integrated in the FM IC (IC200). The IF
IC contains local input, mixer, limiter amplifi er, FM DET, and
low-frequency amplifi er.
The IF signal coming from the IF amplifi er (Q201) goes
to the IF IC mixer and is mixed with the second local signal (38.4MHz) to produce a second IF signal. (38.85MHz –
38.4MHz = 450kHz)
The tripled PLL reference oscillation (12.8MHz x 3) is
used for the second local signal.
The second IF signal passes through ceramic fi lter (CF200)
to remove unwanted signals.
The second IF signal passing through the ceramic fi lter
passes through the limiter amplifi er consisting six differential amplifi ers and is detected.
The amplified second IF signal is demodulated by the
quadrature detector with the ceramic discriminator (CD200).
The demodulated signal is routed to the audio circuit.
Squelch Circuit
■
A squelch circuit is provided to prevent no-signal noise or
weak signals from outputting to a speaker during transmission.
AF Circuit
■
The FM IC output passes through the base band IC
(IC300). The signal then goes through an AF volume control, and is routed to an audio power amplifi er (IC303) where
it is amplfi ed and output to speaker. This IC have BTL amplifi er function. At internal speaker, BTL amplifi ed. At external
speaker, IC switch off the 1 channel amplifi er by connectors
information.
Narrow and wide setting can be made for each channel
by switching the demodulation level. The WIDE (low level)
and NARROW (high level) data is output from IC403, pin
69. When a Wide (low level) data is received, Q200 turn on.
When a NARROW (high level) data is received, Q200 turn
off.
Q200 turns off/on with the wide/narrow data and the
IC200 detector output level is switched to maintained a constant output level during wide or narrow signals.
The audio signal from the microphone passes through
the MIC amplifi er (IC302). Then, the signal goes through the
base band IC (IC300) that has the 6dB/oct pre-emphasis circuit, band-pass fi lter (300 to 3kHz), amplifi er, and limiter. The
distortion components outside the audio band are removed
by the splatter fi lter.
Modulation Circuit
■
The MIC amplifi er (IC302) output passes through VR300
for modulation adjustment and goes to the modulation input
of the VCO circuit for variable reactance phase modulation.
Transmission Output Circuit
■
The VCO output is amplifi ed by a high-frequency amplifi er
(Q101, Q103 and Q104), passes through a high-frequency
antenna switch, passes through a low-pass fi lter and goes
to the antenna.
The transmission output is about 1.5W with 3.8V DC supply at battery terminal.
Low-Pass Filter Circuit
■
A three-stage Chebyshev type low-pass fi lter is located
between the antenna and transmit/receive switching circuit.
It removes harmonic components contained in the transmission output.

The VCO circuit consists of a transistor (Q2), a variable
capacity diode (D2) for frequency control, a variable capacity
diode (D4) for modulation, transmit/receive frequency shift
diode (D1), control transistor (Q1) and oscillator buffer amplifi er (Q5).
In receive mode, the shift signal T/R goes low, Q1 turns
off, and the shift diode (D1) not contact. Q2 produces the
fi rst local frequency for reception. (Receive channel frequency – 38.85MHz)
In transmit mode, the shift signal T/R goes high, Q1
turns on and D1 does conducts. Q2 produces about
460~470MHz and the VCO frequency equals the transmit
channel frequency.
The 3.0V circuit voltage is produced by ripple removing

PLL Circuit
■
Frequency data is sent to the PLL IC (IC1) from the MCU
(IC403) as serial data when the power turns on, when the
channel is changed, or when transmission begins. It sets
the variable divider in the PLL IC.
The TCXO (X1) produce a 12.8MHz reference frequency.
It is divided to produce a 6.25kHz/5kHz PLL comparison frequency in the PLL IC.
This PLL IC can generate a channel step which is twice of
the PLL comparison frequency. Hence, the PLL IC can directly generate channel step by 12.5kHz/10kHz. Beside, an
external control voltage of TCXO is used to shift TCXO reference frequency by 6.25kHz/5kHz to achive channel step
with 6.25kHz/5kHz generate in the PLL IC.

TCXO (X1) 产生 12.8M H z 基准频率,随后在 P L L I C 中分频

该 P LL IC 可以产生两倍于 PLL 比较频率的信道步长。因
此,PLL IC 可以直接产生 12.5kHz/10kHz 的信道步长。此外,

CIRCUIT DESCRIPTION /
The VCO output is divided by the divide ratio set by the
divider in the PLL IC to generate 6.25kHz/5kHz. It is compared with the reference comparison frequency by the
phase comparator to detect a phase difference.
The charge pump circuit in the PLL IC converts it to a
control voltage that can drive the VCO directly.
The control voltage passes through a loop filter which
passes low frequency and is applied to the VCO control pin
to control the oscillator frequency. The loop fi lter removes
unwanted harmonics and noise contained in the output from
the phase comparator and determines PLL response and
synchronizing characteristics by the amplitude and phase
characteristics (Fig. 8).
Unlock Detection Circuit
■
If the PLL cannot be synchronized for some reason or
other when switching the channel or changing between
transmission and reception, the PLL IC outputs a low unlock detection signal. This signal goes to the MCU to inhibit
transmission when the PLL is unlocked.
