[Elecraft] Failure of RS-232 Comms to K3 - when cold?

[Don Wilhelm]

Roger,

I have never seen a similar failure reported here on this reflector, and 
I recommend that you try the K3 on another serial port (a real RS-232 
port if possible) to determine whether it is a problem in the K3 or a 
problem with the USB to RS-232 adapter in the Navigator.
