Stephanie, Vic and Roger already gave you the two best answers for the potential cause. Check RFC15 with an ohmmeter first (do not depend on a test which checks the voltage on each end of RFC15 - the voltage can read the same and it still can be open).
If RFC15 is OK, then start looking for whatever things could cause magnetic coupling into the cores of T5 and L30. Move the K2 as far away from transformers as possible is the best solution - Elecraft does have an optional kit to magnetically shield T5 should you find that is the only solution. 73, Don W3FPR > -----Original Message----- > > I've got a problem in my K2 that is really noticable in CW, although > it is there in all modes.
