AM AGC System
The LA1780M RF AGC is picked up from three locations.
The wide AGC determined by Rw
The middle AGC picked up from the pin 49 second mixer input
The operating bandwidth is 150 kHz to 180 kHz (the bandwidth of the 10.7 MHz CF)
The narrow AGC picked up from pin 52
The operating bandwidth is 7 kHz (the bandwidth of the 450 kHz CF)
No. 5724-29/38
