[Elecraft] K3 Intermittent Line Out Audio

[Don Wilhelm]

Bill,

A look at the K3 schematics will reveal that none of the Line Out 
signals flow through any of the contacts on the headphone jack.
I believe your experience is just "happenstance" and the real source of 
your problem will be found elsewhere.

It seems to center around the front headphone jack.  With no line out audio, I can sometimes put my headphone plug into and out of the front jack and the audio comes back on.   No changes were made to programs (MixW, JF65-HF, etc.) or radio settings.  I have sprayed DeoxIT on the jack with some success but over time the fix does not seem to last long.  Currently, however, I have had the radio off for about the last 6 weeks and it is now doing just fine.  Really aggravating!  Does it make sense that the headphone jack is the problem?   I could not find any reference to this problem in the archives.  Thanks!
