TM-610 Service Manual Circuit Description 1. Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 49.95MHz and the second is 450KHz. The first local oscillator signal is supplied by the PLL circuit; and the second (50.4MHz) is generated from the frequency tripling of TCXO (16.8MHz).
TM-610 Service Manual 2.3 IF Amplifier The first IF signal is amplified by Q113 and then enters IC102 (TA31136FN), where the signal is mixed again with the second local oscillator signal (50.4MHz) to become a 450KHz second IF signal. The second IF signal is then fed through a ceramic filter (N: CF202;...
TM-610 Service Manual 3.1 MIC and Modulation Circuit The audio signal from MIC is amplified by IC405 before being pre-emphasized and encoded by IC401. The output audio signal is added into signalling and then is fed through VCO for modulation.
