[Elecraft] AGC Modification to the K2

[Darwin, Keith]

This is interesting.  I've noticed the K2 AGC doesn't seem to work like
"other rigs".  Specifically, the K2's AGC seems to be less aggressive in
reducing IF gain in the presence of a big signal.  This means the K2
produces more audio dynamic range than other rigs I've used.  The quiet
background noise (or signals) are indeed quieter than the louder strong
signals.  For casual QSOs this means I have a higher signal to noise
ratio for more pleasant copy.

Does this mod do anything to make the AGC more aggressive?

I have never been able to get my AGC set to where I felt it should be. 
Regardless of where the AGC threshold trimmer (R1) is set, there is
always more receiver gain with the AGC off. And moving the AGC voltage
down from the recommended 3.8 volt setting reduces the range of the RF
gain control.
