4-1. Preface

The transceiver is programmed by using a personal computer, a programming interface (KPG-22/22A), USB adapter (KCT-53U) and programming software (KPG-55D (ver.4.00 or later)).

The programming software can be used with a PC. Figure 1 shows the setup of a PC for programming.

4-2. Connection Procedure

1. Connect the transceiver to the personal computer with

the interface cable and USB adapter (when the interface

cable is KPG-22A, the KCT-53U can be used.).

Notes:

• You must install the KCT-53U driver in the computer to

use the USB adapter (KCT-53U).

• When using the USB adapter (KCT-53U) for the ﬁ rst time,

plug the KCT-53U into a USB port on the computer with

the computer power ON.

2. When the POWER is switched on, user mode can be en-

tered immediately. When the PC sends a command, the

transceiver enters PC mode. When data is transmitting from the transceiver, the red

LED lights. When data is received by the transceiver, the green LED

lights.

Notes :

• The data stored in the personal computer must match

the Model Name when it is written into the EEPROM.

• Do not press the [PTT] key during data transmission or

reception.

• Change the transceiver to PC mode, then attach the in-

terface cable.

4-3. KPG-22/KPG-22A Description (PC programming interface cable : Option)

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.

4-4. KCT-53U Description (USB adapter : Option)

The KCT-53U is a cable which connects the KPG-22A to a USB port on a computer.

(L208, L209 and L210). After the signal is ampliﬁ ed (Q203), the signal is filtered through a band pass filter (L203 and L214) to eliminate unwanted signals before it is passed to the ﬁ rst mixer. Band pass ﬁ lters (L208, L209, L210, L203 and L214) have varactor diodes (D203, D204, D205, D202 and D201).

The voltage of these diodes are controlled by to track the MPU (IC403) center frequency of the band pass ﬁ lter. (See Fig. 2)

2) First Mixer

The signal from the RF ampliﬁ er is heterodyned with the ﬁ rst local oscillator signal from the PLL frequency synthesizer circuit at the ﬁ rst mixer (Q202) to create a 38.85MHz ﬁ rst intermediate frequency (1st IF) signal. The ﬁ rst IF signal is then fed through two monolithic crystal filters (MCFs : XF200) to further remove spurious signals.

3) IF Ampliﬁ er

The ﬁ rst IF signal is ampliﬁ ed by Q201, and then enters IC200 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC200 to create a 450kHz second IF signal. The second IF signal is then fed

through a 450kHz ceramic ﬁ lter (CF200) to further eliminate unwanted signals before it is ampliﬁ ed and FM detected in IC200.

4) AF Ampliﬁ er

The recovered AF signal obtained from IC200 is ampliﬁ ed by IC300 (1/4), ﬁ ltered by the IC300 low-pass ﬁ lter (2/4) and IC300 high-pass filter (3/4) and (4/4), and de-emphasized by R303 and C306. The AF signal is then passed through a WIDE/NARROW switch (Q303). The processed AF signal passes through an AF volume control and is ampliﬁ ed to a sufﬁ cient level to drive a loud speaker by an AF power ampliﬁ er (IC302).

the microprocessor (IC403). IC403 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value.

To output sounds from the speaker, IC403 sends a high signal to the MUTE and AFCO Iines and turns IC302 on through Q302, Q304, Q305, Q306 and Q307.(See Fig. 3)

300 Hz and higher audio frequencies of the output signal from IF IC are cut by a low-pass ﬁ lter (IC301). The resulting signal enters the microprocessor (IC403).

3. PLL Frequency Synthesizer

The PLL circuit generates the ﬁ rst local oscillator signal

for reception and the RF signal for transmission.

1) PLL

The frequency step of the PLL circuit is 5 or 6.25kHz.

A 12.8MHz reference oscillator signal is divided at IC1 by a ﬁ xed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer ampliﬁ ed by Q6, then divided in IC1 by a dual-module programmable counter . The divided signal is compared in phase with the 5 or 6.25kHz reference signal in the phase comparator in IC1. The output signal from the phase comparator is ﬁ ltered through a low-pass ﬁ lter and passed to the VCO to control the oscillator frequency. (See Fig.4)

TK-2102G

CIRCUIT DESCRIPTION

2) VCO

The operating frequency is generated by Q4 in transmit mode and Q3 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D1 and

3) Unlock Detector

If a pulse signal appears at the LD pin of IC1, an unlock condition occurs, and the DC voltage obtained from D7, R1, and C1 causes the voltage applied to the UL pin of the microprocessor to go low. When the microprocessor detects this condition, the transmitter is disabled, ignoring the pushto-talk switch input signal. (See Fig.5)

D2 in transmit mode and D3 and D4 in receive mode). The T/R pin is set high in receive mode causing Q5 and Q7 to turn Q4 off, and turn Q3 on . The T/R pin is set low in transmit mode. The outputs from Q3 and Q4 are ampliﬁ ed by Q6 and sent to the buffer ampliﬁ ers.

1) Transmit Audio

The modulation signal from the microphone is ampliﬁ ed by IC500 (1/2), passes through a pre-emphasis circuit, and ampliﬁ ed by the other IC500 (1/2) to perform IDC operation. The signal then passes through a low-pass filter (splatter ﬁ Iter) (Q501 and Q502) and cuts 3kHz and higher frequencies. The resulting signal goes to the VCO through the VCO modulation terminal for direct FM modulation. (See Fig. 6)

2) QT/DQT Encoder

A necessary signal for QT/DQT encoding is generated by IC403 and FM-modulated to the PLL reference signal. Since the reference OSC does not modulate the loop characteristic frequency or higher, modulation is performed at the VCO side by adjusting the balance. (See Fig. 6)

3) VCO and RF Ampliﬁ er

The transmit signal obtained from the VCO buffer ampliﬁ er Q100, is ampliﬁ ed by Q101. This ampliﬁ ed signal is passed to the power ampliﬁ er, Q102 and Q105, which consists of a 2-stage FET ampliﬁ er and is capable of producing up to 5W of RF power. (See Fig.7)

The transmit/ receive switching circuit is comprised of D101, D102, D103 and D104. D102 and D103 turned on (conductive) in transmit mode and off (isolated) in receive mode.

5) APC

The automatic power control (APC) circuit stabilizes the transmitter output power at a predetermined level by sensing the drain current of the ﬁ nal ampliﬁ er Field Effect Transistor (FET) . The voltage comparator, IC100 (2/2), compares the voltage obtained from the above drain current with a reference voltage which is set using the microprocessor. An APC voltage proportional to the difference between the sensed voltage and the reference voltage appears at the output of IC100 (1/2). This output voltage controls the gate of the FET power amplifier, which keeps the transmitter output power constant. The transmitter output power can be varied by the microprocessor which in turn changes the reference voltage and hence, the output power.

6) Thermal Protection Circuit

When the thermistor (TH100) reaches about 80˚C, the protection circuit turns on Q107 to protect transmitting ﬁ nal ampliﬁ er (Q105) from the over heating.

5. Power Supply

A 5V reference power supply [5M] for the control circuit is derived from an internal battery. This reference is used to provide a 5V supply in transmit mode [5T], a 5V supply in receive mode [5R], and a 5V supply common in both modes [5C] based on the control signal sent from the microprocessor.

6. Control System

The IC403 MPU operates at 7.37MHz . This oscillator has a circuit that shifts the frequency according to the EEPROM data.
