[Elecraft] K3 No Receive, No Transmit - SOLVED

[Alan Sewell N5NA]

You were right Guy.  My rig ran fine all day yesterday and then last 
night I had the same problem.  Opened it up and used some needle-nose 
pliers on the TMP connectors to twist and push.  I was able to insert a 
couple a little further and found one was only about half inserted.  
Maybe I have it this time!
