4-1 Circuit Description Reception and transmission are switched by "RX" and "TX" lines from the microprocessor unit (MPU). The receiver uses double-conversion super-hetero- dyne circuitry, with a 43.95MHz 1st IF and 450 kHz 2nd IF. The 1st LO, produced by a PLL synthesizer, yields the 43.95MHz 1st IF. The 2nd LO uses a 43.5 MHz [...]
