5-3. KPG-36/36A description

(PC programming interface cable: Option)The KPG-36/36A is required to interface the transceiver

to the computer. It has a circuit in its D-subconnector (KPG-36: 25-pin, KPG-36A: 9-pin) case that converts the RS-232C logic level to the TTL level.

The KPG-36/36A connects the universal connector of the transceiver to the computers RS-232C serial port.

5-4. Programming software descriptionThe KPG-74D programming disk is supplied in 3-1/2” disk

format. The software on this disk allows a user to program the transceivers via programming interface cable (KPG-36/36A).

5-5. Programming with PCIf data is transferred to the transceiver from a PC with

the KPG-74D, the destination data (basic transceiver infor-mation) for each set can be modifi ed. Normally, it is not nec-essary to modify the destination data because their values are determined automatically when the frequency range (frequency type) is set.

The values should be modified only if necessary. Data can be programmed into the fl ash memory in RS-232C for-mat via the universal connector.

6. Firmware Programming Mode

6-1. PrefaceFlash memory is mounted on the transceiver. This al-

lows the transceiver to be upgraded when new features are released in the future. (For details on how to obtain the fi rm-ware, contact Customer Service.)

6-2. Connection procedureConnect the transceiver to the personal computer with

the interface cable (KPG-36/36A). (Connection is the same as in the PC Mode.)

6-3. Programming1. Start up the programming software (Fpro.exe).2. Set the communications speed (normally, 57600 bps)

and communications port in the comfi guration item.3. Set the fi rmware to be updated by fi le name item.4. Turn the transceiver power ON with the [S] switch held

down. When “PROG 57600” appears, release your fi nger from

the switch.5. Check the connection between the transceiver and the

personal computer, and make sure that the transceiver is in the Program mode.

6. Press write button in the window. A window opens on the display to indicate progress of writing. When the transceiver starts to receive data. the icon is blinking.

7. If writing ends successfully, the LED on the transceiver lights and the checksum is displayed.

8. If you want to continue programming other transceivers, repeat steps 4 to 7.

Notes:• This mode cannot be entered if the Firmware Program-

ming mode is set to Disable in the Programming soft-ware (KPG-74D).

• When programming the firmware, it is recommend to copy the data from the fl oppy disk to your hard disk be-fore update the transceiver fi rmware.

Directry copying from the fl oppy disk to the transceiver may not work because the access speed is too slow.

6-4. Function1. If you press the [Side 2] switch while “PROG 57600” is

displayed, the checksum is displayed. If you press the [Side 2] switch again while the checksum is displayed, “PROG 57600” is redisplayed.

2. If you press the [Side 1] switch while “PROG 57600” is displayed, the display changes to “PROG 19200” to in-dicate that the write speed is low speed (19200 bps). If you press the [Side 1] switch again while “PROG 19200” is displayed, the display changes to “PROG 38400”, and the write speed becomes the middle-speed mode (38400 bps). If you press the [Side 1] switch again while “PROG 38400” is displayed, the display returns to “PROG 57600”.

Note:Normally, write in the high-speed mode.

7. Clone Mode

Programming data can be transferred from one trans-ceiver to another by connecting them via their external uni-versal connectors. The operation is as follows (the transmit transceiver is the master and the receive transceiver is a target).

1. Turn the source transceiver power ON with the [C] key held down. If the password is set to the transceiver, the transceiver displays “CLONE LOCK”. If the “Data Password” is not set, the transceiver displays “CLONE MODE”.

2. When “CLONE LOCK” is displayed, only the [Encoder] knob and [S] key can be accepted. When you enter the correct password, and “CLONE MODE” is displayed, the transceiver can be used as the cloning source. The fol-lowing describes how to enter the password.

3. How to enter the password with the [Encoder] knob; If the [Encoder] knob is rotated while “CLONE LOCK” is displayed, numbers (0 to 9) are displayed fl ashing. When you press the [S] key, the currently selected number is determined. If you press the [S] key after entering the password in this procedure, “CLONE MODE” is displayed if the entered password is correct. If the pass-word is incorrect, “CLONE LOCK” is redisplayed.

4. Power on the target transceiver.5. Connect the cloning cable (No. E30-3325-05) to the uni-

versal connectors on the source and target.

CIRCUIT DESCRIPTION

1. Overview

This transceiver is VHF/FM portable transceiver designed to operate in the frequency range of 136 to 174MHz (K) and a VHF/FM band EFJ LTRTM trunked system compatible FM portable transceiver that can be programmed to operate on both LTR and conventional systems.

2. Circuit Confi guration by Frequency

The receiver is a double-conversion superheterodyne with a fi rst intermediate frequency (IF) of 44.85MHz and a second IF of 455kHz. Incoming signals from the antenna are mixed with the local signal from the PLL to produce the fi rst IF of 44.85MHz.

This is then mixed with the 44.395MHz second local oscillator output to produce the 455kHz second IF. This is detected to give the demodulated signal.

The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the microphone. It is then amplifi ed and sent to the antenna.

3. Receiver System

3-1. RF unitAn incoming RF signal from the antenna terminal is

passed through the antenna switch (D102, D103, D104 and D105 are off) and then the bandpass fi lter (L215, L217). The bandpass fi lter is adjusted by a variable capacitor. The input voltage to the variable capacitor is regulated by the voltage output from the D/A converter (IC307). The signal is ampli-fi ed by RF amplifi er (Q207), and passed through the band-pass fi lter (L210, L213).

The resulting signal is applied to the fi rst mixer (Q206), where it is mixed with the first local oscillator signal out-put from the frequency synthesizer to produce the fi rst IF (44.85MHz).

3-2. IF unitThe fi rst IF signal is passed through a four-pole monolith-

ic crystal fi lter (XF202) to remove a adjacent channel signal. The fi ltered fi rst IF signal is amplifi ed by the fi rst IF amplifi er (Q205) and then applied to the lF system IC (IC200). The IF system IC provides a second mixer, second local oscillator, limiting amplifi er, quadrature detector and RSSI (Received Signal Strength Indicator). The second mixer mixes the fi rst IF signal with the 44.395MHz of second local oscillator out-put (crystal unit X200) and produces the second IF signal of 455kHz.

The second IF signal is passed through the ceramic fi lter (CF200; Wide, CF201; Narrow) to more remove the adjacent channel signal. The fi ltered second IF signal is amplifi ed by the limiting amplifier and demodulated by the quadrature detector with ceramic discriminator (CD200). The demodu-lated signal is routed to the audio circuit.

3-3. Wide/Narrow switching circuitNarrow and Wide settings can be made for each channel

by switching the ceramic fi lters CF200 (Wide), CF201 (Nar-row).

The WIDE (high level) and NARROW (low level) data is output from IC311.

Regardless of NARROW or WIDE band selection, signals always pass through the fi lter, CF200.

When the WIDE band is selected, Q201 is turned ON, then D202 and D203 are turned OFF.

So, the signal does not pass through the filter CF201. When the NARROW band is selected, Q201 is turned OFF, then D202 and D203 are turned ON. So, the signal passes through the fi lters, CF200 and CF201.

Q503 turns on/off with the Wide/Narrow data and the IC200 detector output level is changed to maintain a con-stant output level during wide or narrow signals.

3-4. Audio amplifi er circuitThe demodulated signal from IC200 goes through the

mute switch (Q204) and is amplified by IC300 (2/2), high-pass filtered, low-pass filtered, high-pass filtered, band-eliminate fi ltered, and de-emphasized by IC500.

The signal then goes through an AF amplifi er IC305 (2/2), an electronic volume control (IC307), and an AF switch (Q308 is on), and is routed to audio power amplifi er (IC313), where it is amplifi ed and output to the internal speaker.

The audio mute signal (AM1) from the shift register becomes Low in the standby and Q302, Q303 which are power supply circuit for IC313 turn off. Also, IC500 is set to the power down mode according to data from MCU, and the AF signal is muted. When the audio is output, AM1 be-comes High to turn Q302, Q303 ON, and voltage is supplied to power terminal VP of IC313. Also, IC500 is canceled out of the power down mode.

The speaker is switched by the logic of speaker switch-ing terminal SSW on the universal connector. When SP-MIC is not attached, the logic of SSW becomes High and SW (Q308) is turned ON, and the AF signal is input to both am-plifi ers of IC313.

When SP-MIC is attached, SSW is connected to GND at inside of SP-MIC. For this reason, Q308 is turned OFF, and the AF signal is input only to amplifi er for EXT SP of IC313.

3-5. Squelch circuitThe output from IC200 enters FM IC again, then passed

through a band-pass fi lter. And passed through a band-pass fi lter IC201 (2/2). The noise component output from IC201 (2/2) is amplifi ed by Q208 and rectifi ed by D201 to produce a DC voltage corresponding to the noise level.

The DC voltage is sent to the analog port of the MCU (IC309). And IC200 outputs a DC voltage (RSSI) correspond-ing to the input of the IF amplifi er. The MCU reads the RSSI signal via pin 93.

IC309 determines whether to output sounds from the speaker by comparing the input voltage of pin 91 and pin 93 with the preset value.

4. Transmitter System

4-1. Microphone amplifi erThe signal from the internal microphone goes through

the mute switch (Q301).When the SP-MIC is not attached, the microphone

switching terminal (MSW) on the universal connector be-comes High, and mute switch (Q301) is turned ON. When the SP-MIC is attached, MSW is connected to GND at inside of SP-MIC. For this reason, Q301 is turned OFF, the internal microphone is muted, and only the input of the external mi-crophone is supplied to the microphone amplifi er.

The signal from microphone passes through the micro-phone mute switch (Q502 is off in TX), the limiter circuit in D501 and amplifi ed by IC501 (1/2), and passes through the high-pass fi lter, the ALC circuit, the low-pass fi lter, the high-pass filter, and pre-emphasis/IDC circuit in IC500 on the small board. When encoding DTMF, mute switch (Q501) is turned OFF for muting the microphone input signal.

The signal passes through the D/A converter (IC307) for the maximum deviation adjustment, and enters the sum-ming amplifi er consisting of IC305 (1/2), and is mixed with the low speed data from the MCU (IC309).

The output signal from the summing amplifier passes through the D/A converter (IC307) again and goes to the VCO modulation input.

The other output signal from the summing amplifier passes through the D/A converter (IC307) again for the BAL adjustment, and the buffer amplifi er (IC302: 2/2), and goes to the TCXO modulation input.

4-2. Drive and Final amplifi erThe signal from the T/R switch (D101 is on) is amplifi ed

by drive amplifi er (Q100 and Q101) to +15~17dBm.The output of the drive amplifi er is amplifi ed by the RF

power amplifier (Q106) to 5.0W (1W when the power is low). The RF power amplifier is MOS FET transistor. The output of the RF power amplifi er is then passed through the harmonic filter (LPF) and antenna switch (D102, D103 are on) and applied to the antenna terminal.

4-3. APC circuitThe APC circuit always monitors the current flowing

through the drive amplifi er (Q103) and the RF power ampli-

fi er (Q106) and keeps a constant current. The voltage drop at R119, R120 and R125 is caused by the current fl owing through the RF power amplifi er and this voltage is applied to the differential amplifi er (IC100 1/2).

IC100 (2/2) compares the output voltage of IC100 (1/2) with the reference voltage from IC307, and the output of IC100 (2/2) controls the VGG of the drive amplifi er and the RF power amplifi er to make the both voltages to same volt-age.

The change of power high/low is carried out by the change of the reference voltage. Q105,Q107 and Q108 are turned on in transmit and the APC circuit is active.

5. Frequency Synthesizer Unit

The frequency synthesizer consists of the TCXO (X1), VCO, PLL IC (IC1) and buffer amplifi ers.

The TCXO generates 16.8MHz. The frequency stability is 1.5ppm 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 8 of the PLL IC.

The VCO of this transceiver consists of 2VCO and covers a dual range of the 180.85~218.85MHz and the 136~174MHz. The VCO generates 180.85~218.85MHz for providing to the fi rst local signal in receive. The operating frequency is generated by Q3 in transmit mode and Q2 in receive mode. The oscillator frequency is controlled by ap-plying the VCO control voltage, obtained from the phase comparator (IC1) to the variable capacitor diodes (D1 and D3 in transmit mode and D2, D4, D9 and D10 in receive mode).

The T/R pin of IC312 goes “low” in receive mode caus-ing Q6 and Q3 to turn off, and Q2 and Q4 turn on. The T/R pin goes “high” in transmit mode.

The outputs from Q2 and Q3 are amplifi ed by buffer am-plifi er (Q5) come to the amplifi ers.

The PLL IC consists of a prescaler, reference divider, phase comparator and charge pump. The frequency step of the PLL circuit is 10, 12.5 or 15kHz (Channel step is 5, 6.25 or 12.5kHz). The input signal from the pins 5 and 8 of the

PLL IC is divided down to the 10, 12.5 or 15kHz and com-pared at phase comparator. The pulsed output signal of the phase comparator is applied to the charge pump and trans-formed into DC signal in the loop fi lter (LPF). The DC signal is applied to the CV of the VCO and locked to keep the VCO frequency constant.

PLL data is output from DP (pin 73), CP (pin 74) and EP (pin 72) of the MCU (IC309). 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 30 (UL) of the MCU. When the PLL is unlocked, the UL goes low.

6. Control Circuit

The control circuit consists of MCU (IC309) and its pe-ripheral circuits. It controls the TX-RX unit and transfers data to and from the display unit. IC309 mainly performs the fol-lowing;1) Switching between transmission and reception by PTT

signal input.2) Reading system, group, frequency, and program data

from the memory circuit.3) Sending frequency program data to the PLL.4) Controlling squelch on/off by the DC voltage from the

squelch circuit.5) Controlling the audio mute circuit by decode data input.6) Transmitting tone and encode data.

6-1. Memory circuitMemory circuit consists of the MCU (IC309) and a fl ash

memory (IC308), a fl ash memory has a capacity of 2M bits that contains the transceiver control program for the MCU and data such as transceiver channels and operating fea-tures.

This program can be easily written from an external de-vices. Data, such as operating status, are programmed into the EEPROM (IC310).

■ Flash memoryNote: The fl ash memory holds data such as written with the FPU (KPG-74D), fi rmware program (User mode, Test mode, Tuning mode, etc.) This data must be rewritten when replac-ing the fl ash memory.

■ EEPROMNote: The EEPROM stores tuning data (Deviation, Squelch, etc.). Realign the transceiver after replacing the EEPROM.

6-2. Low battery warningThe battery voltage is monitored by the MCU (IC309).

When the battery voltage falls below the voltage set by the Low Battery Warning adjustment, the red LED flashes to

notify the operator that it is time to replace the battery. If the battery voltage falls even more (Ni-Cd, Ni-MH: approx. 5.8V, Li-ion: approx. 6.1V), a beep sounds and transmission is stopped.

Low battery warning Battery condition

The red LED fl ashes during transmission

The battery voltage is low but the transceiver is still usable.

The red LED fl ashes and con-tinuous beep sounds while PTT pressed

The battery voltage is low and the transceiver is not usable to make calls.

6-3. Battery type detectionThe transceiver automatically detects the battery type,

measuring the resistance between the S-terminal and + ter-minal on the battery pack and changes the supplied voltage to the S-terminal as below. The MCU then detects the bat-tery type.

Resistor value Battery type Input voltage of S-terminal

OPEN Battery case 0~0.3V

7. Signaling Circuit

7-1. Encode

■ Low-speed data (QT, DQT, LTR)Low-speed data is output from pin 1 of the MCU. The

signal passes through a low-pass CR fi lter, and goes to the summing amplifi er (IC305 1/2). The signal is mixed with the audio signal and goes to the VCO and TCXO (X1) modulation input after passing through the D/A converter (IC307) for BAL adjustment.

■ High-speed data (DTMF)High-speed data is output from pin 2 of the MCU. The

signal passes through a low-pass fi lter consisting of IC304, and provides a TX DTMF tone and a RX DTMF tone. TX DTMF deviation making an adjustment by MCU is passed through the D/A convertor (IC307) and then applied to the audio processor (IC500).

The signal is mixed with the audio signal and goes to the VCO and TCXO. The RX DTMF tone is passed a summing amplifier (IC305 2/2). The D/A converter (IC307) for audio control, audio power amplifi er and then to the speaker.

■ MSK (ESN)ESN utilizes 1200bps MSK signal. MSK signal is output

from pin 6 of IC500. The signal passes through the D/A converter (IC307) for the MSK deviation adjustment, and is routed to the VCO. When encoding MSK, the microphone input signal is muted.

7-2. Decode

■ Low-speed data (QT, DQT, LTR)The demodulated signal from the IF IC (IC200) is ampli-

fied by IC300 (2/2) and passes through a low-pass filter (IC306) to remove audio components. The signal is input to pin 95 of the MCU.

The MCU digitizes this signal, performs processing such as DC restoration, and decodes the signal.

■ High-speed data (DTMF)The DTMF input signal from the IF IC (IC200) is amplifi ed

by IC300 (2/2) and goes to IC301, the DTMF decoder. The decoded information is then processed by the MCU. During transmission and standby, the DTMF IC is set to the power down mode when the PD terminal is High. When the line is busy, the PD terminal becomes Low, the power down mode is canceled and decoding is carried out.

■ High-speed data (2 tone)The demodulated signal from the IF IC (IC200) is ampli-

fi ed by IC300 (2/2) and passes through an audio processor (IC500) and band-pass fi lter IC303 (1/2) and IC 201 (1/2) to remove a low-speed data. The MCU digitizes this signal, performs processing such as DC restoration, and decodes the signal.

8. Power Supply Circuit

Battery +B is supplied via a 3A fuse from the battery terminal connected to the TX-RX unit. After passing through the power switch, power supply (SB) is applied to the three AVRs. IC401 supplies 5V (5M) to the control circuit, and IC403 supplies 5V (5C) to common circuits. IC402 supplies to the TX circuit, the RX circuit and common circuits of needless save mode. During transmission, 5TC becomes Low and Q405 is turned ON to supply 5V (5T) to the TX circuit. During reception, 5RC becomes Low and Q404 is turned ON to supply 5V (5R) to the RX Circuit.

The power supply voltage monitor IC (IC404) monitors power supply voltage (SB). If the voltage falls (less than 5V), the VOUT port goes “LOW” level, the MCU INT port also goes “LOW” level, and the MCU stops.

ADJUSTMENT

■ Antenna connector adapterThe antenna connector of this transceiver uses an SMA

terminal. Use an antenna connector adapter [SMA(f) – BNC(f) or SMA(f) – N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

Note: When the antenna connector adapter touches the knob, draw out the knob to mount the connector.

■ Universal connectorUse the interface cable (KPG-36) for PC tuning or the

lead wire with plug (E30-3287-28) and screw (N08-0535-08) for panel tuning. Connect the plug to the universal connec-tor of the transceiver and tighten the screw.

The lead wire with plug (E30-3287-28) and screw (N08- 0535-08) terminals are as follows. Numbers are universal connector terminal numbers.

Caution:1. When connecting the plug to the universal connector of

the transceiver, a short circuit may occur. To prevent this, be sure to turn the transceiveer POWER switch off.

2. Since the RX AF output is a BTL output, there is a DC component. Isolate this with a capacitor or transformer as shown in the fi gure.

3. Do not connct an instrument between red or black and GND.

■ Repair jig (Chassis)Use jig (part No.: A10-4060-04) for repairing the TK-2140.

Place the TX-RX unit on the jig and fi t it with screws.The jig facilitates the voltage check and protects the fi nal

amplifi er FET when the voltage on the fl ow side of the TX-RX unit is checked during repairs.

■ Battery jig (W05-0909-00)Connect the power cable properly between the battery

jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.

Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, be-tween the power supply and the battery jig, especially while the transceiver transmits.
