[Elecraft] K2 intermittent problem

[Igor Sokolov]

Just discovered that knocking RF board in the region of the K14 and K15 
relays makes the problem to appear or disappear. The offset does not depend 
on the CW pitch  setting and is close to 1 khz.

My K2 developed a problem. In CW mode TX frequency is off the RX frequency
by about 1 kHz. The problem is intermittent. Sometimes it manifests itself,
sometimes it does not.
Can anybody give me a hint where to look? I was about to see if changing CW
pitch changes the offset but so far cannot make the problem to appear again.
So far there were no evidence that the problem is temperature dependant.
