[Elecraft] headphones in phone jack makes meter go up ...

[Don Wilhelm]

Was the nut on the headphone jack tightened sufficiently to make the 
washer behind the panel tight?  If not, there is a possibility that the 
board is moving a bit when the headphones are plugged in (or removed) 
and may cause "strange happenings".
Squeeze the board and front panel metal together and snug up the 
headphone jack nut to strong finger tightness.
