Any pics of how you mounted and wired it or the part number and vendor
of the part you got to replace it? I'm planning a K2 build soon as I
sell some radios. So I was trying to get the pieces in place from the
start.

Kirk,
Sounds as though the internal switch in your headphone jack has failed,
and the only practical fix I believe is to replace it. Since 2003 the
switch in the original headphone jack and its replacement in my K2 have
failed, and I now use a robust headphone jack mounted on the rear panel.

Subject: [Elecraft] No speaker audio
I recently discovered that my external speaker fails to work after
pulling out my headphones. I checked the resistance of the speaker and
it reads 8 ohms, and the DC voltage across the plug (P5) is almost
nothing. The DC voltage out of the audio amp U9 (Pin #6) reads 13
volts. R35/36 should be ok because the headphones work fine.
I think J2 is the problem and could be called a TIF (toddler induced
failure). My son was sitting on my lap listening to "beeping" and he
tugged on the headphone cord. Could this have damaged the internal
switch, keeping it stuck in headphone mode? Is there any way to fix
this?
