[Elecraft] K3 AF audio problems

[Scott Avery]

Hello All,

Today, I was enjoying working some DX etc.
All the sudden the AF audio out of my external speaker was all distorted and cracking up.
If I advance the AF gain past 12 O'clock distortion happens on the external & internal speaker.
The Phone output is ok and not affected. Sounds normal at full volume, but NOT main speaker!
When changing the audio gain parameter in menu from high to low, no distortion, but the same as 12 O'clock position on AF gain.
Also, When powering up, sometimes the main speaker will not work, but phones do.
If I cycle the power to the K3, Sometimes, when audio set above 12 O'clock, the audio will sound good for a split
second, then the radio backs off the audio automatically, and sounds like crap.

Currently running latest beta software. Did revert back to older software, but no change.

Any help appreciated!
