INTRODUCTION

SCOPE␣ OF␣ THIS␣ MANUAL

This manual is intended for use by experienced technicians familiar with similar types of commercial grade communications equipment. It contains all required service information for the equipment and is current as of this publication date. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions, which are issued as required.

ORDERING␣ REPLACEMENT␣ PARTS

When ordering replacement parts or equipment information, the full part identification number should be included. This applies to all parts : components, kits, and chassis. If the part number is not known, include the chassis or kit number of which it is a part and a sufficient description of the required component for proper identification.

PERSONNEL␣ SAFETY

The following precautions are recommended for personnel safety :

• DO␣ NOT␣ transmit if someone is within two feet (0.6

meter) of the antenna.

• DO␣ NOT␣ transmit until all RF␣ connectors are secure and

any open connectors are properly terminated.

• SHUT␣ OFF this equipment when near electrical blasting

caps or while in an explosive atmosphere.

• All equipment should be properly grounded before

power-up for safe operation.

• This equipment should be serviced by only qualified tech-

nicians.

PRE-INSTALLATION␣ CONSIDERNATIONS

1. UNPACKING

Unpack the radio from its shipping container and check for accessory items. If any item is missing, please contact KENWOOD␣ immediately.

2. LICENSING␣ REQUIREMENTS

Federal regulations require a station license for each radio installation (mobile or base) be obtained by the equipment owner. The licensee is responsible for ensuring transmitter power, frequency, and deviation are within the limits permitted by the station license.

Transmitter adjustments may be performed only by a licensed technician holding an FCC␣ first, second or general class commercial radiotelephone operator’s license. There is no license required to install or operate the radio.

3. PRE-INSTALLATION␣ CHECKOUT 3-1. Introduction

Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation.

3-2. Testing

The radio should be tested complete with all cabling and accessories as they will be connected in the final installation. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. Signalling␣ equipment operation should be verified.

4. PLANNING␣ THE␣ INSTALLATION 4-1. General

Inspect the vehicle and determine how and where the radio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crushing wiring, and radio installation to prevent overheating.

4-2. Antenna

The favored location for an antenna is in the center of a large, flat conductive area, usually at the roof center. The trunk lid is preferred, bond the trunk lid and vehicle chassis using ground straps to ensure the lid is at chassis ground.

5. INSTALLATION␣ PLANNING – CONTROL␣ STATIONS 5-1. Antenna system

Control station. The antenna system selection depends on many factors and is beyond the scope of this manual. Your KENWOOD␣ dealer can help you select an antenna system that will best serve your particular needs.

5-2. Radio location

Select a convenient location for your control station radio which is as close as practical to the antenna cable entry point. Secondly, use your system’s power supply (which supplies the voltage and current required for your system). Make sure sufficient air can flow around the radio and power supply to allow adequate cooling.

SERVICE

This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and alignment procedures contained in this manual.

NOTE

If you do not intend to use the 3.5-mm jack for the external speaker, fit the supplied speaker-jack cap to stop dust and sand getting in.

4-3. Radio

The universal mount bracket allows the radio to be mounted in a variety of ways. Be sure the mounting surface is adequate to support the radio’s weight. Allow sufficient space around the radio for air cooling. Position the radio close enough to the vehicle operator to permit easy access to the controls when driving.

4-4. DC␣ Power and wiring

1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse

to blow. Check the vehicle ground polarity before installa-

tion to prevent wasted time and effort.

2. Connect the positive power lead directly to the vehicle

battery positive terminal. Connecting the Positive lead to

any other positive voltage source in the vehicle is not rec-

ommended.

3. Connect the ground lead directly to the battery negative

terminal.

4. The cable provided with the radio is sufficient to handle

the maximum radio current demand. If the cable must be

extended, be sure the additional wire is sufficient for the

current to be carried and length of the added lead.

• Scan ON/OFF

Press this key starts scanning. Pressing this key stops

scanning.

• Talk around

Press this key, the transceiver uses the receive fre-

quency and the tone for transmission.

The operator can call the other party directly (without repeater). Press this key again, the talk around function goes off.

• Temporary delete

The "Add" channel contained in the scan sequence, and "Delete" channel is not contained. In the scan mode, this key switches the channel delete temporarily (Press and hold for approximately one second).

When the transceiver is turned off, the transceiver exits the scan or switches the scan function off.

• None

Sounds error operation beep, and no action will occur. Use this function when the transceiver is required to be more simple operated.

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 programmed key LED blinks.

■ 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.

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.

■ 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

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.

■ Scan end

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.

TK-7102

OPERATING␣ FEATURES

■ Temporary delete

It is possible to delete channel temporary during scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete function (for example press and hold the key for approximately one second), 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.

5. Details of Features

■ Time-out timer

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

■ PTT ID

PTT ID provides a DTMF ANI to be sent with every time PTT (beginning of transmission, end of transmission, or both).

You can program PTT ID "on" or "off" for each channel. The contents of ID are programmed each Radio.

The timing that the transceiver sends ID is programmable.

BOT : DTMF ID (Beginning of TX) is sent on beginning of

transmission.

EOT : DTMF ID (End of TX) is sent on end of transmis-

sion.

Both : DTMF ID (Beginning of TX) is sent on beginning of

transmission and DTMF ID (End of TX) is sent on end of

transmission.

■ Off hook decode

If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no effect for decoding QT/DQT and option signalling.

■ "TOT" pre-alert

The transceiver has "TOT" pre-alert timer. This parameter 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.

■ Clear to transpond

The transceiver waits the transpond of DTMF if channel is busy until channel open. This feature prevents the interference 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.

If option signalling matches on a channel is set up with option signalling, the channel LED will flash and option signalling 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.

■ SP Unmute

You can select the type of SP Unmute system for each channel. The selection is as follows.

Carrier, QT/DQT:

Channel with this option will not check ID Code in order to open its speaker.

Carrier+DTMF, QT/DQT+DTMF:

Channel that is set with this option will have to check for ID Code in order to open its speaker.

■ "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

The transceiver has "TOT" reset timer. This timer is the minimum wait time allowed during a transmission that will reset the "TOT" count.

"TOT" reset time causes the "TOT" to continue even after PTT is released unless the "TOT" reset timer has expired.

Note:

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

If option signalling matches a group set up with option signalling, option signalling is released. After matching option signalling, option signalling will temporarily reset automatically.

CIRCUIT DESCRIPTION

Frequency Configuration

The receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the neces-

sary frequencies. Figure 1 shows the frequencies.

Receiver System

The receiver is double conversion superheterodyne. The

frequency configuration is shown in Figure 1.

■ Front-end RF Amplifier

An incoming signal from the antenna is applied to an RF amplifier (Q26) after passing through a transmit/receive switch circuit (D31 is off) and a band pass filter (L36, L38 and varactor diodes: D25, D26). After the signal is amplified (Q26), the signal is filtered through a band pass filter (L30, L32 and varactor diodes: D21, D22) to eliminate unwanted signals before it is passed to the first mixer.

The voltage of these diodes are controlled by tracking the CPU (IC6) center frequency of the band pass filter. (See Fig.

■ First Mixer

The signal from the RF amplifier is heterodyned with the first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer (Q21) to create a 49.95MHz first intermediate frequency (1st IF) signal. The first IF signal is then fed through two monolithic crystal filters (MCFs : XF1) to further remove spurious signals.

■ IF Amplifier

The first IF signal is amplified by Q19, and the enters IC5 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC5 to create a 450kHz second IF signal. The second IF signal is then fed through a 450kHz ceramic filter (Wide : CF1, Narrow : CF2) to further eliminate unwanted signals before it is amplified and FM detected in IC5.

■ Wide/Narrow Changeover Circuit

The Wide port (pin 92) and Narrow port (pin 91) of the CPU is used to switch between ceramic filters. When the Wide port is high, the ceramic filter SW diodes (D13, D15) cause CF1 to turn on to receive a Wide signal.

When the Narrow port is high, the ceramic filter SW diodes (D13, D15) cause CF2 to turn on to receive a Narrow signal.

■ AF Signal System

The detection signal from IF IC (IC5) goes to AF amp (IC3) to adjust the gain and is output to AF filter (IC10) for characterizing the signal. The AF signal output from IC10 and the DTMF signal, BEEP signal are summed and the resulting signal goes to the D/A converter (IC3). 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 (IC16). The AF signal from IC16 switches between the internal speaker and speaker jack (J1) output.

■ Squelch Circuit

The detection output from the FM IF IC (IC5) passes through a noise amplifier (Q18) to detect noise. A voltage is applied to the CPU (IC6). The CPU controls squelch according to the voltage (SQIN) level. The signal from the RSSI pin of IC5 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.

PLL Frequency Synthesizer

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 IC1 by a fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q15, then divided in IC1 by a dualmodule 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 filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 6)

■ VCO

The operating frequency is generated by Q11 in transmit mode and Q10 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D10 and D12 in transmit mode and D9 and D11 in receive mode). The TX/RX pin is set low in receive mode causing Q12 and Q7 to turn Q11 off, and turn Q10 on. The TX/RX pin is set high in transmit mode. The outputs from Q10 and Q11 are amplified by Q15 and sent to the buffer amplifiers.

■ Unlock Circuit

During reception, the 8RC signal goes high, the 8TC signal goes low, and Q29 turns on. Q31 turns on and a voltage is applied to the collector (8R). During transmission, the 8RC signal goes low, the 8TC signal goes high and Q30 turns on. Q33 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC1) LD signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this signal and makes the 8TC signal low. When the 8TC signal goes low, no voltage is applied to 8T, and no signal is transmitted.

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.

■ Power Amplifier Circuit

The transmit output signal from the VCO passes through the transmission/reception selection diode (D19) and amplified to a specified level of the power module (IC101) by the drive block (Q23 and Q25). The amplified signal goes to a low-pass filter. The low-pass filter removes unwanted highfrequency harmonic components, and the resulting signal is goes the antenna terminal.

CIRCUIT DESCRIPTION

■ APC Circuit

The automatic transmission power control (APC) circuit detects part of a power module output with a diode (D34, D36) and applies a voltage to IC12. IC12 compares the APC control voltage (PC) generated by the D/A converter (IC3) and DC amplifier (IC4) with the detection output voltage to control Q27 and Q28, generates DB voltage from B voltage, and stabilizes transmission output.

The APC circuit is configured to protect over current of the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and temperature variations.

Control Circuit

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 (IC10) and turns

the filter select compounder on or off.

3) Controls the DTMF decoder (IC9).

4) Controls the display unit.

5) Controls the PLL (IC1).

6) Controls the D/A converter (IC3) and adjusts the volume,

modulation and transmission power.

■ Display Circuit

The CPU (IC6) controls the display LEDs. When the transceiver is busy, the LEDG line goes high, Q4 turns on and the green LED (D11) lights. In transmit mode, the LEDR line goes high, Q8 turns on and the red LED (D12) lights. Backlit LEDs (D1~D4) are provided.

When a function key (MON, PF, C1, C2, C3 or C4) is selected, its respective line goes high (LED MON, LED PF, LED C1, LED C2, LED C3 or LED C4), the switch connected to that line turns on and the amber LED lights.

■ Key Matrix Circuit

The TK-7102 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 always low.

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 corresponding to that port has been pressed.

CIRCUIT DESCRIPTION

■ Encode

The QT and DQT signals are output from QT/DQT of the CPU (IC6) and summed with the external pin DI line by the summing amplifier (IC4) and the resulting signal goes to the D/A converter (IC3). The DTMF signal is output from DTMF of the CPU and goes to the D/A converter (IC3). The signal is summed with a MIC signal by the summing amplifier (IC4), and the resulting signal goes to the D/A converter (IC3).

The D/A converter (IC3) 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.

■ Decode

• QT/DQT/DTMF

The signal (DEO) passes through two low-pass filters of IC11, goes to QTIN of the CPU (IC6) to decode QT, DQT. The DTMF signal is decoded by a dedicated IC (IC9) and the resulting signal is sent to the CPU (IC6) as serial data.

■ D/A Converter

The D/A converter (IC3) is used to adjust MO modulation, AF volume, TV voltage, FC reference voltage, and PC POWER CONTROL voltage level.

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 to CPU port 18 (POWER), goes low, then CPU port 93 (SBC) goes high, Q34 turns on, SB SW (Q42) turns on and power (SB) is supplied to the radio.

This circuit has an overvoltage protection circuit. If a DC voltage of 18 V or higher is applied to the power cable, D39 turns on and a voltage is applied to the base of Q38. This voltage turns Q38 on and turns Q34 and SB off.
