[Elecraft] [K2] Pinout for J2 (headphone jack)

[Don Wilhelm]

Bill,

The front-most pin is the ground pin, and is the one that provides more 
mechanical stability than any of the others - So if it is mechanical 
stability you are after, re-solder all 8.

There is a tiny bit of looseness in the jack mounting to its grounding 
lug due to the mechanical assembly of the jack itself. That is not 
normally a problem even though it is bothersome to some.  if it 
maintains good electrical contact with the plug, you might want to leave 
it alone.

73,
