TK-7102H 14 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 necessary frequencies. Figure 1 shows the frequenci...

TK-7102H 15 ■ Wide/Narrow Changeover Circuit The Wide port (pin 65) and Narrow port (pin 64) of the CPU is used to switch between ceramic filters. When the Wideport is high, the ceramic filter SW diodes (D303, D302) causeCF301 to turn on to receive a Wide signal. When the Narrow port is high, the ce...

TK-7102H 16 ■ Unlock Circuit During reception, the 8RC signal goes high, the 8TC signal goes low, and Q34 turns on. Q33 turns on and a voltage isapplied to the collector (8R). During transmission, the 8RCsignal goes low, the 8TC signal goes high and Q36 turns on.Q35 turns on and a voltage is applied...

TK-7102H 17 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 (IC251) and turns the filter select compounder on or off. 3) Controls the display unit.4) Controls the PLL (IC401).5) Controls the D/A conv...

TK-7102H 18 ■ Decode • QT/DQT/DTMF The signal (W/NO (EVOL2)) goes to SIGNAL (pin 88) of CPU (IC101). The QT/DQT signal will pass through the low-pass filters in the CPU (IC101) and be decoded within theCPU (IC101). The DTMF signal will be decoded within theCPU (IC101). ■ D/A Converter The D/A conver...
