AGC Peak Detector Decay
Setting a higher decay time will cause the locked AGC gain to be lower when the audio
input level drops towards zero. This will reduce the background noise level when the
channel is idle but slightly reduce the AGC response time.


1. Press P to set the AGC Peak Detector Decay:
decay (sec.) = A:0.25, B:0.5, C:1.0, D:2.0, E:3.0, F:4.0,
