1-53. HOMER-DETECTOR AMPLIFIER ASSEMBLY A4600. (CONT)
OFF COURSE SIGNAL AMPLIFIER
EL1AT131
The homer if.-am signal, isolated by transistor Q4809, is applied to sensitivity amp Q4810. The bias
level of Q4810 is established by if. agc voltage from the if. agc amp.
When the received homing signal is of a low level, if. agc voltage causes transistor Q4810 to conduct
harder allowing more of the homing signal to be applied to the synchronous detector.
