Dear Igor & Others,
May I speculate?
Any AGC compresses the dynamic range of incoming signals. AGC means
Automatic Gain Control. If you had an invisible hand that would
adjust the RF gain control for you, that is what AGC does.
When you are working many stations on the same frequency and they are
very close to zero beat turning off the AGC creates a greater dynamic
range in the ear of the receiving operator and thus gives an
additional tool to separate the signals.
When I was a commercial operator at KPH, nearly all the operators ran
AGC off all the time. It makes the QRM/QRN fade away.

Eric, can you explain what did you not like about AGC in K3?
Did you notice any problems with DSP being permanently on in K3 when
listening to heavy pile ups?
