2-6. Programming with IBM PC
3-1. Outline
If data is transferred to the transceiver from an IBM PC
with the KPG-108D, the data for each set can be modified.
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
lines respectively.
”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.
3-2. Example
The transceiver can copy the programming data to one
or more transceivers via RF communication.

CIRCUIT DESCRIPTION
■ IF Amplifier
The IF circuit is integrated in the FM IC (IC200). The IF
IC contains local input, mixer, limiter amplifier, FM DET, and
low-frequency amplifier.
The IF signal coming from the IF amplifier (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 filter
(CF200) to remove unwanted signals.
The second IF signal passing through the ceramic
filter passes through the limiter amplifier consisting six
differential amplifiers 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 amplifier (IC303)
where it is amplfied and output to speaker. This IC have BTL
amplifier function. At internal speaker, BTL amplified. At
external speaker, IC switch off the 1 channel amplifier by
connectors information.

Transmitter System
■ Microphone Amplifier Circuit
The audio signal from the microphone passes through
the MIC amplifier (IC302). Then, the signal goes through
the base band IC (IC300) that has the 6dB/oct pre-emphasis
circuit, band-pass filter (300 to 3kHz), amplifier, and limiter.
The distortion components outside the audio band are
removed by the splatter filter.
■ Modulation Circuit
The MIC amplifier (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 amplified by a high-frequency
amplifier (Q101, Q103 and Q104), passes through a highfrequency antenna switch, passes through a low-pass filter
and goes to the antenna.
The transmission output is about 1.5W with 3.8V DC
supply at battery terminal.

MHz
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.
A three-stage Chebyshev type low-pass filter is located
between the antenna and transmit/receive switching
circuit. It removes harmonic components contained in the
transmission output.

CIRCUIT DESCRIPTION
In receive mode, the shift signal T/R goes low, Q1 turns
off, and the shift diode (D1) not contact. Q2 produces
the first 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
filter circuit Q4.
PLL System
■ VCO Circuit
The VCO is housed in a shield case.
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), variable capacitor (TC1)
for PLL lock voltage control, and oscillator buffer amplifier
(Q5).

VCO circuit
■ PLL Circuit
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 filter 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).
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.
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
■ 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.

CIRCUIT DESCRIPTION
Control System
■ Reset Circuit
When a battery voltage is dropped, IC401 is detected
low voltage, and this detected signal input to IC403 for stop
the MCU function. IC400 is detected the reset voltage.
■ Battery Voltage Detection Circuit
The unit detects a low battery voltage and display the
BATT indicator on the LCD. The battery voltage is divided
and applied to the analog value input pin (BATT) of the MCU,
and converted to a digital signal.
■ QT/DQT
• Encode (Transmit)
QT/DQT signal is generated by MCU (IC403). Output
signal (IC403 pin 18 (TO)) goes to TCXO modulation and
VCO modulation (Through the VR300).
• Decode (Receive)
Detected AF signal go to IC300 and then IC301. Function
of IC301 is LPF for sub-audible frequency. This signal goes
to IC403 pin 77 (TI). IC403 is detected the QT or DQT.
B
The power supply voltage is maintained to 3.0V by the
series regulator (IC404). It is used as MCU power 3M, 3C,
3R and 3T.
The B (battery voltage) is supplied to the RF final
transistor Q104.
The transmission power 3T is supplied to the
transmission output circuit when the MCU turns Q404 on
only in transmit mode.
The reception power 3R is provided to the receive and IF
circuits when the MCU turns Q406 on only in receive mode.
The transmission/reception power 3C is supplied to
the VCO and PLL circuits when the MCU turns Q405 on in
transmit and receive modes.
If no signal is received for 10 seconds, the MCU enters
the power save mode, and turns common power 3C and
reception power 3R on for one cycle and off for three cycles
according to the signals from the MCU to save the battery
power.
