[Elecraft] K2 Ser no. 3181

[Dale Boresz]

Hello Ron,

Your AGC threshold has a huge effect on  the range of adjustment of the 
RF gain control. If the AGC threshold is set too high - meaning that you 
are generally operating with very little AGC action - your RF gain 
control will have very little effect. If you lower your threshold, 
you'll find that the RF gain control will have a much greater effect.

Just a reminder, R1 on the control board is what controls this 
threshold, and in the K2 manual, the information relating to this 
adjustment is located right next to the info about the S-meter 
alignment. (page 46 in my Rev D manual for S/N 3039, so it's probably 
the same version as yours).

Hope this helps.

73, Dale / WA8SRA
