TK-7102H

OPERATING FEATURES

■ PTT ID

4. Scan Operating

■ SCAN start condition

Two or more channels must be added to all channels that

can be scanned. The transceiver must be in normal receive

mode (PTT off).

When you activate the key programmed to the scan ON/

OFF function, the scan starts. The indicator next to the pro-

grammed key LED blinks.

PTT ID provides a DTMF ANI or MSK ID to be sent with

every time PTT (connect ID at beginning of transmission, dis-

connect ID at end of transmission, or both).

You can program PTT ID “on” or “off” for each group

channel (DTMF). The contents of ID are programmed for

each transceiver.

The transceiver is capable to have ID. The format is

DTMF. The timing that the transceiver sends ID is program-

mable.

■ Scan stop condition

The scan stops temporarily if the following conditions are

satisfied.

1) A carrier is detected, then QT/DQT matches on channels

for which receive the QT/DQT is set by the programming

software.

BOT : Connect ID is sent on beginning of transmission.

EOT : Disconnect ID is sent on end of transmission.

Both : Connect ID is sent on beginning of transmission

and disconnect ID is sent on end of transmission.

There is also “PTT ID” setting for each channel.

2) A carrier is detected on the channels for which receiving

QT/DQT is not set by the programming software or when

the monitor (signalling cancel) function is activated.

■ Off hook decode

If the Off hook decode function has been enabled, remov-

ing and replacing the microphone on the hook has no effect

for decoding QT/DQT and option signalling.

■ Revert channel

The revert channel is used to transmit during scanning and

set by the programming software (KPG-70D).

1) Selected channel

The transceiver reverts to the channel before scanning or

the channel that you changed during scan.

2) Selected with talkback

■ “TOT” pre-alert

The transceiver has “TOT” pre-alert timer. This param-

eter selects the time at which the transceiver generates

“TOT” pre-alert tone before “TOT” is expired.

“TOT” will be expired when the selected time passes

from a TOT pre-alert tone.

The transceiver reverts to the selected channel prior to

scan initiation.

However, if a call is received on a channel other then the

selected channel and PTT is pressed before scanning re-

sume, the transceiver “talks back” on the current receive

channel.

■ “TOT” re-key time

The transceiver has “TOT” re-key timer. This timer is the

time you can not transmit after “TOT” exceeded. After

“TOT” re-key time expired you can transmit again.

■ “TOT” reset time

■ Scan end

The transceiver has “TOT” reset timer. This timer is the

minimum wait time allowed during a transmission that will

reset the “TOT” count.

When you press the key programmed to the scan function

during scan mode, the scan ends.

The indicator next to the programmed key LED turns off.

“TOT” reset time causes the “TOT” to continue even af-

ter PTT is released unless the “TOT” reset timer has expired.

■ Temporary delete

It is possible to delete channel temporary during scan.

When scan stops on unnecessary channel for example by in-

terference of the other party, activate the delete function (for

example press and hold the key for approximately one sec-

ond), then that channel is deleted temporarily and scan re-

start immediately.

The temporary deleted channels return to pre-set delete/

add channels, when the transceiver is turned off or the scan

function is switched off.

■ Clear to transpond

The transceiver waits the transpond of DTMF if channel is

busy until channel open. This feature prevents the interfer-

ence to other party.

6. Option Signalling (DTMF)

Built-in DTMF decoder is available for option signalling.

It is possible to use individual call, group call, Stun.

If the option signalling matches, a predetermined action

will occur.

5. Details of Features

■ Time-out timer

If option signalling matches on a channel is set up with

option signalling, the channel LED will flash and option signal-

ling will be released. The transpond or alert tone will sound.

While option signalling matches (or if option signalling is

deactivated when you are transmitting), you can mute or

unmute QT/DQT/Carrier.

The time-out timer can be programmed in 30 seconds in-

crements from 30 seconds to five minutes and off. If the

transmitter is transmitted continuously for longer than the

programmed time, the transmitter is disabled and a warning

tone sounds while the PTT button is held down. The warning

tone stops when the PTT button is released.

alert is set, the tone sounds at the amount of time pro-

grammed, before the TOT expires (TOT time – TOT pre alert

time = Pre alert tone sounding time). You can select yes or

no for the optional feature’s warning tone.

When QT/DQT is not used, QT/DQT and QT/DQT+DTMF

can not be selected.

When DTMF is not used, Carrier+DTMF and QT/

DQT+DTMF can not be selected.

■ Auto Reset

■ Transmit protection

If option signalling matches a group set up with option sig-

nalling, option signalling is released. After matching option

signalling, option signalling will temporarily reset automati-

cally.

The final FET is protected against heat while transmitting

by making the radio cuts down TX power when the tempera-

ture of the final FET becomes higher than reference. After

that, if the temperature continue to rise, transmission is

stopped. The final FET is also protected against over voltage

by having the radio to check that the voltage of power supply

connected to the radio is not higher than about 17V when the

radio is turned on, otherwise it can not transmit. In both

cases when transmission is stopped, a beep will continue to

sound until the PTT key is released.

■ Stun

If the stun code matches, a predetermined action will oc-

cur. Whether option signalling is activated or not, when stun

matches on any channel, the transceiver will become TX in-

hibited or TX/RX inhibited. While stun is active, if the stun

code + “#” code is received, stun will deactivate.

When stun matches, transpond will function. Alert will

not be output.

CIRCUIT DESCRIPTION

■ IF Amplifier

Frequency Configuration

The first IF signal is amplified by Q351, and the enters

IC301 (FM processing IC). The signal is heterodyned again

with a second local oscillator signal within IC301 to create a

450kHz second IF signal. The second IF signal is then fed

through a 450kHz ceramic filter (Wide : CF301, Narrow :

CF302) to further eliminate unwanted signals before it is am-

plified and FM detected in IC301.

The receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil-

lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessary

frequencies. Figure 1 shows the frequencies.

■ Front-end RF Amplifier

An incoming signal from the antenna is applied to an RF

amplifier (Q353) after passing through a transmit/receive

switch circuit (D603, D604, D605 are off) and a band pass

filter (L357, L356 and varactor diodes : D353, D354). After

the signal is amplified (Q353), the signal is filtered through a

band pass filter (L354, L355 and varactor diodes: D351,

D352) to eliminate unwanted signals before it is passed to

the first mixer.

CIRCUIT DESCRIPTION

■ Wide/Narrow Changeover Circuit

■ Squelch Circuit

The Wide port (pin 65) and Narrow port (pin 64) of the CPU

is used to switch between ceramic filters. When the Wide

port is high, the ceramic filter SW diodes (D303, D302) cause

CF301 to turn on to receive a Wide signal.

The detection output from the FM IF IC (IC301) passes

through a noise amplifier (Q301) to detect noise. A voltage is

applied to the CPU (IC101). The CPU controls squelch ac-

cording to the voltage (SQIN) level. The signal from the RSSI

pin of IC301 is monitored. The electric field strength of the

receive signal can be known before the SQIN voltage is input

to the CPU, and the scan stop speed is improved.

When the Narrow port is high, the ceramic filter SW di-

odes (D303, D302) cause CF302 to turn on to receive a Nar-

row signal.

PLL Frequency Synthesizer

D303

D302

The PLL circuit generates the first local oscillator signal for

reception and the RF signal for transmission.

■ PLL

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

16.8MHz reference oscillator signal is divided at IC401 by a

fixed counter to produce the 5 or 6.25kHz reference fre-

quency. The voltage controlled oscillator (VCO) output signal

is buffer amplified by Q410, then divided in IC401 by a dual-

module programmable counter. The divided signal is com-

pared in phase with the 5 or 6.25kHz reference signal in the

phase comparator in IC401. The output signal from the

phase comparator is filtered through a low-pass filter and

passed to the VCO to control the oscillator frequency. (See

Fig. 6)

Narrow

IC101 64pin

Fig. 3 Wide/Narrow changeover circuit

■ AF Signal System

The detection signal from IF IC (IC301) goes to D/A con-

verter (IC161) to adjust the gain and is output to AF filter

(IC251) for characterizing the signal. The AF signal output

from IC251 and the DTMF signal, BEEP signal are summed

and the resulting signal goes to the D/A converter (IC161).

The AFO output level is adjusted by the D/A converter. The

signal output from the D/A converter is input to the audio

power amplifier (IC252). The AF signal from IC252 switches

between the internal speaker and speaker jack (J1) output.

■ VCO

The operating frequency is generated by Q406 in transmit

mode and Q405 in receive mode. The oscillator frequency is

controlled by applying the VCO control voltage, obtained

from the phase comparator, to the varactor diodes (D405 and

D406 in transmit mode and D403 and D404 in receive mode).

The TX/RX pin is set low in receive mode causing Q408 and

Q407 to turn Q406 off, and turn Q405 on. The TX/RX pin is

set high in transmit mode. The outputs from Q405 and Q406

are amplified by Q410 and sent to the RF amplifiers.

CIRCUIT DESCRIPTION

■ Unlock Circuit

Transmitter System

■ Outline

The transmitter circuit produces and amplifies the desired

frequency directly. It FM-modulates the carrier signal by

means of a varicap diode.

During reception, the 8RC signal goes high, the 8TC signal

goes low, and Q34 turns on. Q33 turns on and a voltage is

applied to the collector (8R). During transmission, the 8RC

signal goes low, the 8TC signal goes high and Q36 turns on.

Q35 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC401) LD

signal directly. When the PLL is unlocked during transmis-

sion, the PLL LD signal goes low. The CPU detects this sig-

nal and makes the 8TC signal low. When the 8TC signal goes

low, no voltage is applied to 8T, and no signal is transmitted.

■ Power Amplifier Circuit

The transmit output signal from the VCO passes through

the transmission/reception selection diode (D409) and ampli-

fied by Q501, Q502 and Q503. The amplified signal goes to

the final amplifier (Q504) through a low-pass filter. The low-

pass filter removes unwanted high-frequency harmonic com-

ponents, and the resulting signal is goes the antenna termi-

nal.

Q33

Q35

■ APC Circuit

Q34

Q36

The automatic transmission power control (APC) circuit

detects part of a final amplifier output with a diode (D606,

D607) and applies a voltage to IC501. IC501 compares the

APC control voltage (PC) generated by the D/A converter

(IC161) and DC amplifier (IC203) with the detection output

voltage. IC501 generates the voltage to control Q503 and

Q504 and stabilizes transmission output.

TK-7102H

CIRCUIT DESCRIPTION

■ Key Matrix Circuit

Control Circuit

The TK-7102H front panel has function keys. Each of

them is connected to a cross point of a matrix of the KMI1 to

KMO2 ports of the microprocessor. The KMO1 to KMO2

ports are always high, while the KMI1 to KMI4 ports are al-

ways low.

The CPU carries out the following tasks:

1) Controls the WIDE, NARROW, TX/RX outputs.

2) Adjusts the AF signal level of the AF filter (IC251) and

turns the filter select compounder on or off.

3) Controls the display unit.

The microprocessor monitors the status of the KMI1 to

KMO2 ports. If the state of one of the ports changes, the

microprocessor assumes that the key at the matrix point cor-

responding to that port has been pressed.

4) Controls the PLL (IC401).

5) Controls the D/A converter (IC161) and adjusts the vol-

ume, modulation and transmission power.

■ Encode

The QT and DQT signals are output from QT/DQT of the

CPU (IC101) and summed with the external pin DI line by the

summing amplifier (IC203) and the resulting signal goes to

the D/A converter (IC161). The DTMF signal is output from

DTMF of the CPU and goes to the D/A converter (IC161). The

signal is summed with a MIC signal by the summing amplifier

(IC203), and the resulting signal goes to the D/A converter

(IC161).

The D/A converter (IC161) adjusts the MO level and the

balance between the MO and QT/DQT levels. Part of a QT/

DQT signal is summed with MO and the resulting signal goes

to the VCOMOD pin of the VCO. This signal is applied to a

varicap diode in the VCO for direct FM modulation.

Fig. 11 Memory circuit

■ Display Circuit

The shift register controls the display LEDs through the CL

and DI lines from the CPU (IC101).

When the transceiver is busy, LED G line becomes high

impedance, turning on Q4 and the green LED (D11) lights, in

transmit mode, the LED R line becomes low impedance, and

the red LED (D12) lights.

Backlit LEDs (D1~D4) are provided and will only goes off

when MBL line becomes low impedance.

When a function key (MON, PF, C1, C2, C3 or C4) is se-

lected, its respective line becomes low impedance (LED

MON, LED PF, LED C1, LED C2, LED C3 or LED C4), the

amber LED lights.

■ D/A Converter

The D/A converter (IC161) is used to adjust MO modula-

tion, AF volume, TV voltage, FC reference voltage, and PC

POWER CONTROL voltage level.

Fig. 16 Power supply circuit

Adjustment values are sent from the CPU as serial data.

The D/A converter has a resolution of 256 and the following

relationship is valid:

D/A output = (Vin – VDAref) / 256 x n + VDAref

Vin: Analog input

VDAref: D/A reference voltage

n: Serial data value from the microprocessor (CPU)

Power Supply Circuit

When the power switch on the display unit is pressed, the

power port on the display unit which is connected port 17

(POWER), goes low, then port 82 (SBC) goes high, Q32 turns

on, SB SW (Q31) turns on and power (SB) is supplied to the

radio.

When the DC power supplied to the radio, the voltage

regulator IC (IC33) supply into the CPU VDD and reset voltage

detect IC (IC34). IC34 will generate signal (RESET) in to the

reset terminal on the CPU (IC101) to carry out a power ON

reset. Also, CPU (IC101) is checking on port 91 (Battery Volt-

age). If DC power is less than about 9.5V, the radio is unable

to power on.

When the DC power voltage deceases from normal volt-

age, the INT voltage detector IC (IC35) will set to high on CPU

port 18 (INT) if B line will became less than about 9.5V. Then

CPU send to EEPROM (IC66) the backup data and go into

STOP mode.

4. Connect 50Ω load at the ANT location.

If normal power is not obtained, please follow the

step below

Open the shielding cover (upper), and screw 3 locations

around ANT pin.

Transmit and check current drain at High power mode.

If the current drain is less than 1A, then Final FET is bro-

ken.

If the current drain is less than 5.0A, short the Drive FET

gate to ground, and check the current drain.

If the current drain is not 0.1A less than the original value,

then the Drive FET is broken.

1. Switch off the transceiver.

Impedance of Final FET (Q504) and Drive FET (Q503) can

be measured easily using DVM Ω mode.

Normal condition – Gate : 20kΩ~50kΩ, Drain : 1MΩ~2MΩ

The above impedance values are rough estimations.

2. Switch on the transceiver. Check the voltage at F501 out-

put point.

5. Check input power level at Drive FET gate location.

Connect the wire to [RF] location.

Transmit and check for power to be within the range of

0.3W~0.6W.

If power found is less than 0.3W, check the circuit before

the Drive FET.

The voltage is around 13.6V in receiving condition. The

voltage will be 12.6V~ in transmitting condition. If found

0V at this point then F501 is broken.

3. Remove R516.
