FM muting on level
adjustment
Modify the value of the external
resistor to adjust the muting on
level.
47
RF AGC rectification capacitor
The low frequency distortion is
determined as follows:
Increasing C48 and C57 improves
the distortion but makes the
response slower.

RF AGC bypass
RF AGC
Reducing C48 and C57
aggravates the distortion but
makes the response faster.

51
IF bypass
FM IF input
Due to the high gain of the limiter
amplifer, care must be taken when
choosing the grounding point for
the limiter amplifer input capacitor
to prevent oscillation.
