Headphone Jack Problem with K1

[George Averill]

All,
I just discovered that the headphone jack on my K1 is cracked and needs replacing.  I understand that this is a weak point in the K1.  Can anyone advise me on the best way to remove the old jack?  Has Elecraft come up with a stronger replacement jack?  I think the part number is E620028.

George,

To remove the old headphone jack, you can de-solder it if you have good
de-soldering tools.  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.

Unfortunately, there is only one supplier of that jack, and despite past
efforts from Elecraft to attempt to persuade the manufacturer to beef up
the jack, no positive results have occurred.
It is not really *that* weak.  Some have worked for years, yet a small
percentage will fail.  I know that is not a help if you are in that
small percentage category.

I have noticed that my LINE IN jack sometimes loses the input signal and I have to apply a slight pressure to get it restored (gently push in on it).  It's fine after that unless I move the K3.  Does this jack suffer the same issues as the headphone jack too?

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.
