[Elecraft] [K2] where there's the smell of smoke...

  John,

Maybe you are working on it too late :-) .

If the keying stops when the key is removed, I would suspect the key and 
cable rather than the K2.
To see if there is a key jack problem, plug a bare 3.5mm stereo plug 
into the jack.

If your plug is only partly inserted, the dash contact in the key jack 
can be touching the shell - that will key the K2 with dashes momentarily 
until the plug is seated.

As a side-note -- I have found several K2 owners who severely tighten 
the dress nut on the key jack (and the BNC jack as well).  That really 
is not necessary and can damage the jack.  Just tighten a little bit 
beyond finger tight.  The nut holds neither the rear panel nor the jack 
in place, it is just there for appearance - just tight enough to keep 
the nut from backing itself off is sufficient.

73,
Don W3FPR
