  • Page 9 S1 Service manual 1.Radio Principle： 1. Frequency configuration The receiver utilizes double conversion. The first IF is 21.70MHz and the Second IF is 450 KHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequency.
  • Page 10 S1 Service manual to further remove spurious signals. 3） IF amplifier The first IF signal is amplified by Q23, and then enters IC7(modulation processor IC). The signal is heterodyned again with a second local oscillator signal within IC7 to create a 450MHz second IF signal.
  • Page 11 S1 Service manual 1） PLL The frequency step of the PLL circuit is 2.5 or 3.125 or 5 or 6.25KHz. A 13MHz reference oscillator signal is divided at IC4 by a fixed counter to produce the 2.5 or 3.125 or 5 or 6.25 KHz reference frequency.
