Preface The transceiver is programmed by using a personal com- puter, programming interface (KPG-46) and programming software (KPG-79D).
T K-715 0 6 5-5. Programming With IBM PC If data is transferred to the transceiver from an IBM PC with the KPG-79D, the destination data (basic radio informa- tion) for each set can be modified.
T K-715 0 7 1. Installing Name Plate Punch out the name plate card. Then insert the plates onto the relative function keys. You can reconfigure the name plates at any time. 3. External Speaker (KES-5) The external speaker output from the accessory connector (6 pin) on the rear of the transceiver is 13W/4 Ω .
T K-715 0 8 4. Use as Public Address Speaker 1. Remove the short plug from the 6-pin accessory connec- tor on the rear of the radio. (Remove the jumpers as de- scribed 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.

T K-715 0 12 CIRCUIT DESCRIPTION 1. Outline The TK-7150 is a VHF/FM transceiver designed to operate in the frequency range of 136 to 174MHz. Transmission out- put 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.
T K-715 0 13 2-4. Audio Amplifier The recovered audio signal obtained from IC201 is ampli- fied 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 termi- nal of IC713 is amplified and filtered by IC716 (A/2) to a suffi- cient level.
T K-715 0 14 3-4. Automatic Power Control, Circuit and Transmitter The automatic power control (APC) circuit stabilizes the transmitter output power at a predetermined level, and con- sists of forward/reflected power detector circuits.
T K-715 0 15 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.
