[Elecraft] K2 AGC off problem

[Ken K3IU]

I corrected the "typo" in an email to the reflector shortly after re-reading
what I had sent. "u" is right next to "I" on my keyboard <g>

Damn, mine too. #5209. Hold PRE/ATT and AGC, it says "OFF", all bars light
and the K2 goes deaf. Hold them again, it says "On", the bars come down, and
stuff can be heard again. I've not had a chance to measure Ctrl-U2-1.

Doing WHAT to the IF amp? Nice typo!   :-)
