[Elecraft] K2 SSB Watery Audio Distortion

[Don Wilhelm]

John,

You said it is there with and without the KPA100.  Have you physically 
removed the KPA100 and tried it with just the base K2?
If not, please try that.  Should the base K2 be clean, re-install the 
KPA100, but after it is installed, remove the right side panel and 
fold/tuck the ribbon cable and the speaker cable into the area near 
where the ribbon cable attaches to the control board.

Often such a watery sound is caused by coupling from the ribbon or 
speaker back into the KSB2 board - dressing the ribbon and speaker 
cables away from the KSB2 fixes it.

That is at least a starting point.
