I had this problem early with my K3 and was told it is usually one of two things: (1) a board seating problem or (2) a temperature sensitivity problem. Since it occurred when my factory built K3 was only a few months old, they said to send it back for warranty repair.
Of course, when it got to Elecraft the problem did not present itself. They did temperature cycling and the problem did not occur. Likely the shipping jostling seated the board again. Worked fine when I got it back, but the problem did reappear once. Reseating the boards again cured the problem again.
