3-3. KPG-22A Description
(PC programming interface cable: Option)
The KPG-22A is required to interface the transceiver with
the computer. It has a circuit in its D-sub connector (KPG-22A:
9-pin) case that converts the RS-232C logic level to the TTL
level.
The KPG-22A connects the SP/MIC connector of the
transceiver to the RS-232C serial port of the computer.
3-4. KPG-22U Description
(USB programming interface cable: Option)
The KPG-22U is a cable which connects to a USB port
on a computer.
When using the KPG-22U, install the supplied CD (with
driver software) in the computer. The KPG-22U driver runs
under Windows XP, Vista, 7, 8 or 8.1.
3-5. Programming Software KPG-173D Description
The KPG-173D is the programming software for the
transceiver supplied on a CD. This software runs under win-
dows XP, Vista, 7, 8 or 8.1 on a PC. The software on this
disc allows a user to program the transceiver via Program-
ming interface cable (KPG-22A/22U).
3-6. Programming with PC
If data is transferred to the transceiver from a PC with the
FPU, the data for each set can be modified.

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.
CIRCUIT DESCRIPTION
2. Receiver System
The receiver system is shown in Figure 2.
Fig. 1 Frequency configuration
Fig. 2 Receiver system
2-1. Front End (RF Amplifier) Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D102 and D103)
and a BPF, and is then amplified by the RF amplifier (Q204).
The resulting signal passes through a BPF and goes to
the mixer.
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 (CD201).The demodulated signal is routed to
the audio circuit.
2-4. Audio Amplifier Circuit
The demodulated signal from IC200 is amplified by
IC305, IC303,IC620 and goes to AF amplifier through IC302
and IC601.
The signal then goes through an volume control (VR500),
and is routed to an audio power amplifier (IC302,IC601)
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.
Fig. 3 Microphone amplifier circuit
3-2. Driver and Final Amplifier Circuit
The signal from the T/R switch (D100 is on) is amplified
by the drive amplifier (Q101).
The output of the drive amplifier is amplified by the RF
final amplifier (Q102) to 0.85W (50Ω).
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 (D102)
and is applied to the antenna terminal.

CIRCUIT DESCRIPTION
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 446.00~446.20MHz and the 407.15~407.35MHz. The
VCO generates 407.15~407.35MHz 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 PLLEN (pin 20) of the MCU (IC400). The data are input
to the PLL IC when the channel is changed or when trans-
mission is changed to reception and vice versa. A PLL lock
condition is always monitored by the pin 22 (PLLLD) 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 (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
input.
6) Transmitting tone and encode data.
Note:
The EEPROM stores tuning data (Deviation, Squelch,
etc.).
Realign the transceiver after replacing the EEPROM.
6. Signaling Circuit
6-1. Encode
■Low-speed data (QT, DQT)
Low-speed data is output from pin 49 (LSDO) of the MCU
(IC400). 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).
■High-speed data (DTMF)
High-speed data (HSD) 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
■QT/DQT
The output signal from IF IC (IC200) enters the MCU
(IC400) through IC300. IC400 determines whether the QT
or DQT matches the preset value, and controls the SPMUT
and the speaker output sounds according to the squelch re-
sults.
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).

Preparations for Tuning the Transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is tuned, the unit must be con-
nected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ωdummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
