TK - 7 102 TK - 7 102 2 2 47 CONTENTS / GENERAL GENERAL INTRODUCTION SCOPE␣ OF␣ THIS␣ MANUAL This manual is intended for use by experienced techni- cians familiar with similar types of commercial grade com- munications equipment. It contains all required service in- formation for the equipment and is current as of this publica- tion date.
3 T K-71 0 2 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 sys- tem that will best serve your particular needs.
4 T K-71 0 2 1. Controls and Functions 1-1. Front Panel q (Power) switch Press to switch the transceiver ON. Press and hold for approximately 1 seconds to switch the transceiver OFF. w ▲ key Press to increase the volume level. e ▼ key Press to decrease the volume level.
5 T K-71 0 2 2. Operation Features The TK-7102 is a VHF FM radio designed to operate in conventional format. The programmable features are sum- marized. 3. Transceiver Controls and Indicators 3-1. Front Panel Controls All the keys on the front panel are momentary-type push buttons.
6 T K-71 0 2 ■ 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.
7 T K-71 0 2 ■ 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 inhibited or TX/RX inhibited. While stun is active, if the stun code + "#" code is received, stun will deactivate.
8 TK -7102 REALIGNMENT 3-4. Programming Software Description The KPG-70D programming disk is supplied in 3-1/2" disk format. The software on this disk allows a user to program TK-7102 radio via a programming interface cable (KPG-46).
9 TK -7102 1. When you remove the panel, turn the transceiver up side down. Detach the panel by lifting the tabs as shown below. Fig. 1 Fig. 2 DISASSEMBL Y FOR REP AIR 2. To remove the cabinet, first turn the transceiver up side down. Detach the cabinet by prying the tabs as shown below.
10 T K-71 0 2 Frequency Configuration 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 neces- sary frequencies.
11 T K-71 0 2 ■ 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.

13 T K-71 0 2 ■ 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.
14 T K-71 0 2 ■ 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).
