1 MAIN IN
(20) SUB IN
LA1065M
Unit (resistance : Ω, capacitance : F)
External
Notes
The AC component of 114kHz in IF, S meter
output is taken by the BPF and input to pin 1 (or
pin 20) by C coupling.
Be advised that the
LA1065M input impedance
changes with input and can
go to a minimum of 10kΩ.
2 H.P.F.
(19)
3 AGC
(18)
4 Monostable
multi-vibrator
Highpass filter
Increase this capacitor's
value if antenna switching
tends to misoperate.
