In researching desirable AGC characteristics that might be applied to the RS
DX-394 over a year ago, I came across the terms 'delayed' and 'hang'.
Thought they were interchangeable but on reading the ARRL 2004 Handbook, it
seems that 'delayed' means that the attack speed on the RF stages is slower
than on the IF stages or is relatively delayed. According to the HB, "This
prevents a premature increase in the receiver noise figure".

I always thought "delayed AGC" means that there's no gain reduction
unless the strength of the incoming signal reaches a certain threshold.
It's not a delay in time, but in amplitude.
