[Elecraft] [K1] Unusual ATU Problem

[Don Wilhelm]

Mike,

You are correct about the lack of a resettable fuse in the K1. Sorry.
One thing to check is the seating of the microprocessor in its socket.  
Remove it and put it back in just to wipe the contacts a bit which will 
remove oxidation if it exists.  A loose connection to one of the 
microprocessor will create many 'strange happenings'.
