I'm looking for some advice/guidance on the design of AGC detection and
timing circuits, prompted by some level of frustration with a modification I
have been doing to a DX-394 SW radio. My questions, though, probably apply
to receiver design generally. I have a problem with stability - the receiver
gain oscillates at medium and fast release speeds.

I don't know receiver design but I have a RX340 that uses the following
settings. Attack is in dB/mS, Hang in seconds, and Decay are in dB/S.

Attack Hang Decay
Fast .8 0 1600
Medium .8 0 100
Slow .8 0 25

Programable attack .01 to 1 dB/mS
Programable hang 0 to 99.9 seconds
Programable decay .01 to 99.9 dB/S
