[Elecraft] RE: K2 drops receive level

[DOUGLAS ZWIEBEL]

Tim:

I'm no K2 guru, but what you describe is classic of a
poor/intermittent connection somewhere on the way to the antenna.
I've experienced this with many radios, going back many decades.  The
"dit" (transmitting) somehow reestablishes a better connection at the
point of failure.

This might be at any coax connector (from the back of the radio all
the up to the antenna).

Try tracing your coax and connections along the way.  Open up all
contact points and "clean" them up (emery cloth, board, your favorite
contact cleaner, etc).  At the antenna (and elsewhere too), be sure
your connections are not only clean, but tight.

I'll leave the suggestions for what to "trace for" inside the K2 up to
the K2-masters.
