TK-7150 GENERAL 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 data. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions. These are issued as required.
TK-7150 GENERAL / SYSTEM SET-UP 5-2. Radio location SERVICE 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. This radio is designed for easy servicing.

TK-7150 REALIGNMENT 5-5. Programming With IBM PC Firmware checksum display If data is transferred to the transceiver from an IBM PC with the KPG-79D, the destination data (basic radio information) for each set can be modified. Normally, it is not necessary 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.
TK-7150 INSTALLATION 1. Installing Name Plate 3. External Speaker (KES-5) Punch out the name plate card. Then insert the plates onto the relative function keys. You can reconfigure the name plates at any time. The external speaker output from the accessory connector (6 pin) on the rear of the transceiver is 13W/4Ω. Use the KES-5. 3-1.
TK-7150 INSTALLATION 4. Use as Public Address Speaker 1. Remove the short plug from the 6-pin accessory connector on the rear of the radio. (Remove the jumpers as described in Section 3-1.) 2. Cut off the end of the protective cover, insert the speaker cable into the protective cover, and insert it into pins 2 and 3. 3. Install the plug and protective cover on the accessory connector on the rear of the transceiver, then clamp the bottom of the protective cover with the supplied tie wrap. 4.
TK-7150 INSTALLATION 6. Optional Board 6-1. Voice Scrambler Board Connection ■ Modification 1. Remove the cabinet and shielding cover from the transceiver. 2. Remove the panel. 3. Delete R798 and R866 on the TX-RX unit. ■ Connection The functions of pins of CN701 on the foil side of the TXRX unit are shown in the figure. Join the CN701 connector to the voice scrambler board via the E37-0808-05 connector cable. Note : You must setup the FPU.
TK-7150 INSTALLATION 7. Wiring of the Cable for Installing the Built-in Type GPS Unit or Other PC Board 1. Loosen the 2 screws ( 1 ) to remove the D-sub 25-pin connector. 2. Looses the 4 screws ( 2 ) to remove the Hardware fixture. 3. Remove the CN704 connector with the 6-pin lead wire. 4. Take out the Hardware fixture. 5. Cut the packing as shown in the illustratation. 7. Tighten the 4 screws to attach the Hardware fixture. 8. Tighten the 2 screws to fix attach D-sub 25-pin connector.
TK-7150 INSTALLATION 9.

C89 and C90 Positions 1. Ensure to solder C89 and C90 to securely contact Q5. Note : The TX power may vary depending on the position of C89 and C90. Q5 C90 C89 9-2. Soldering 1. Ensure to solder C89 and C90 with the earth spring legs as illustrated in Fig. 9-3.
TK-7150 CIRCUIT DESCRIPTION 2-2. First Mixer 1. Outline The TK-7150 is a VHF/FM transceiver designed to operate in the frequency range of 136 to 174MHz. Transmission output power is 50 watts. The maximum channel capacity is 128. The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, and control circuits.
TK-7150 CIRCUIT DESCRIPTION 2-4. Audio Amplifier 3-1. Microphone Circuit The recovered audio signal obtained from IC201 is amplified and anti-aliasing filtered by IC712 (A/2), inputted to the AINR terminal of CODEC IC (IC713), and audio processed by DSP (IC710). The processed audio signal from AOUTR terminal of IC713 is amplified and filtered by IC716 (A/2) to a sufficient level.
TK-7150 CIRCUIT DESCRIPTION 3-4. Automatic Power Control, Circuit and Transmitter The automatic power control (APC) circuit stabilizes the transmitter output power at a predetermined level, and consists of forward/reflected power detector circuits. The forward/reflected power detector circuits detects forward RF power and reflected RF power to DC voltage, and consists of a C coupling type detection circuit, RF detector D5/D6, and DC amplifier IC2 (A/2).
TK-7150 CIRCUIT DESCRIPTION 5-3. DSP Circuit The DSP circuit filters transmit/receive audio signal and encode/decode signalling (QT, DQT, MSK, DTMF, 2-Tone, LTR ID). This circuit consists of IC710, IC706, IC707, IC708, IC709 and IC713. The receive audio signal is converted from analog to digital by IC713 with a sampling frequency of 19.2kHz. The digitized audio signal is sent to DSP (IC710) to process the signalling signal and audio signal.
