[Elecraft] K3 firmware and AGC question

[Allan Taylor]

I recently had my K3 (S/N 740) updated at the factory with the 2nd
receiver and other relevant mods. It has firmware 2.78 installed and
the rig was received back from Aptos about two weeks ago. Since
receiving it, I have noticed that the Audio gain needs to be cranked
up more than before. The rig never had gobs of rx audio, but I am
finding it at 2 or 3 o'clock most of the time. I was on 30m with the
bandwidth set to about 1.0 kHz and using NR. As a test, I shut down
the AGC and it seems to have plenty of rx audio then (but of course NO
protection...). Turn on NR substantially drops rx audio including
signals...
Even without NR, it seems a bit weak.  I am not a young buck and
hearing is somewhat addled, but no hearing aids yet!

Has anyone noticed changes in rx audio with either installation of the
2nd rx or somewhat updated firmware? If I upgrade to the
latest and greatest (3.11??) what should the AGC settings be for
general use? I know there were lengthy discussions here regarding AGC
parameters, but didn't pay much attention when they came by. Is there
a summary page/wiki somewhere??
