[Elecraft] K2 curious problems

[William Schmidt]

I'm looking for some help with my K2 (SN 5165) that has developed the following problems:

1.  Even after pushing the A=B vfo control, B does not track with the A vfo but remains where it was when the A=B was pushed.

2.  When I turn on the K2 the audio initially sounds fine but after a variable interval it becomes distorted and muffled.  The strange thing is that if I cycle the power off and on the audio returns to normal.  This doesn't affect the transmitter.

The voltages on the 5v and 8v lines measure ok.  I'm not sure if this is a problem with the MCU or with a relay that needs to reset.  Is this a problem that others have noticed?  I'm at a loss as to how to track this down.
