[Elecraft] K3 receive audio erratic

[Larry Boekeloo]

Hi everyone from cold, snowy Michigan.....

Yesterday, my K3 suddenly decided to have erratic receive audio.  If I have the audio at the 9 o'clock position and start to turn it counter-clockwise to lessen the audio, the audio goes to half volume.  I then brought up HRD and I can watch it on the software do the same thing.

One thing...my external speaker was partly out of the K3 yesterday and I pushed it back in without turning the rig off.  Had U1 blown, I would think I would have no audio....

Am I sending the DSP board in for repair?

Thoughts?
