3.1 PLL CIRCUIT 
The Phase Lock Loop (PLL) circuit is responsible for developing the receiver’s first local oscillator 
signal and the transmitter’s exciter signal. The PLL circuit consists primarily of IC2, IC3, IC4, IC5 
Q25, Q27, Q28, Q29 and Q61. The PLL circuit is programmed by the rotary channel switch GPS-0501. 
The switch communicates the correct binary data information to the programmable divider inside of 
IC3. IC3 then controls the VCO (Voltage Controlled Oscillator), consisting of...
