美 Tentec 무전기의 AGC Hang 에 대한 어떤 문답

Your agc voltage is quickly developed across a diode which in turn reduces the gain of the I.F. amp but not quite quick enough to prevent an unatural sounding "pop". Then, suddenly, the signal goes away and the agc voltage remains high thus keeping the I.F. gain at a low level for a determined time. This is the "hang time". During this time, you won't be able to hear weak signals. The S-meter also hangs on 20db during this time. This can be annoying if you are tuning across the band. It's easy to miss those weak signals due to the long hang time. TenTec stopped using it ...
