[Elecraft] K3 3422 gone deaf

[Don Wilhelm]

David,

Open the top cover and check the plugging of all the TMP cables as a 
good starting point.  Check all the areas that you disturbed to see if 
anything is out of place.
I doubt the firmware is the problem, but you could certainly try another 
firmware load just to be certain.  Make sure the firmware finishes 
loading - if it is abnormally terminated, the K3 will not work.
You could try an EEINIT and then set up all the menus from scratch.
