[Elecraft] Headphone Jack Problem with K1

[Don Wilhelm]

Jeff,

That is an entirely different jack used in the K3 (and KX3).

The retention on many 3.5mm jacks is not strong, and with only a slight 
pull on the cable, the plug will become slightly unseated.  I don't 
think the ones used by Elecraft are any worse than the ones I have seen 
on many computer soundcards.

If not, crush the body of the old jack (pliers will work) sufficiently so you can remove the old pins one at a time.  Do whatever you need to do to preserve the thru-plated solder holes (do *not* drill out the holes.
