[Elecraft] Mic Problem?

Ken,

Sounds like you found the source - part of the ground system.  I would still
recommend grounding the mic jack in any case - I do that routinely as part
of any K2 that I have on the bench for upgrade.

For what it is worth, in the case of cables, I always look for the source of
a cable break right at the point where the cord flexes most - normally right
at the point where the 'strain relief' device ends - I have found this to be
true especially on portable power tools, but it also occurs on mic and key
cables too - cut 2 or 3 inches off the cable and re-connect everything and
intermittent problems such as that vanish.

73,
Don W3FPR
