[Elecraft] K3 S meter oddities

[Phillip Shepard]

It actually does it with a blank phone plug inserted.  As soon as the plug
goes in, the S meter jumps up.  The signal itself does not change, just the
meter reading.  I have not examined the area around the jack inside to see
if there is anything odd.  That may be next.

My K3 s/n 559 running 4.39 does -not- exhibit this behavior. As far as I can
recall, it never has. Using Koss and Yamaha phones here. On what bands/under
what conditions? Is it possible you are actually coupling some kind of RF
(not necessarily ham transmissions, but something else in the house/shack)
back into the rig from within your environment via the phones lead?
