vari-cap D15 and D16 to make the phases equal. In result the stabilized
oscillation can be done at the desired frequency.
The 2nd Local
IC1 compares the frequency gained by dividing the signal added to pin 19 of
IC1 by the control signal from IC7 with the frequency gained by dividing the
reference frequency of 12.8 MHz inside IC1. When the phase difference is
found as a result of phase comparison, the pulse signal is output from the
charge pump output of pin 13 of IC1, then the signal is converted into the DC
voltage at the inside circuit for active filter and added to the cathode side of
VCO vari-cap D20 and D21 to make the phases equal. In result the stabilized
oscillation can be done at the desired frequency.
