Hi Martin - My K3 is on its second headphone jack, due to symptoms like
yours. Recently it started doing this again, but I was inside the radio
for another issue and reseated some boards (including KIO3 if I remember
correctly) and it stopped happening. You might look into that before
you replace hardware.

Elecrafters,
i think the headphone jack on my K3 #2878 is failing. Audio drops out
now and then, but returns when i plug in a headphone.
When I set menu item SPKRS & PHONE YES I have no drop outs.
There is no part number for the headphone jack in the assembly manual.
IIRC the front pcb came with the jack already installed.
Any hint how to try a repair prior to fire up the soldering iron is
highly welcome.
What to do if a repair fails?
Thanks,
Martin
