[Elecraft] K3 Bricked HELP!!

[Mark Bayern]

I strongly suggest following Don's one cable at a time troubleshooting
method.

In my shack the error was caused when I pushed the paddles out of the way
so I could place a notebook computer with the firmware files near the K3.
After the update, I got the ERR PTT. Felt pretty dumb when I realized I
caused it by pushing the paddles into another object. Is your cat taking a
nap on top of the key? hi hi
