[Elecraft] K3 error message help needed

[Don Wilhelm]

Paul,

Something is closing either the key or paddles or PTT - if you have the 
RS-232 port set to key or PTT fom either DTR or RTS, that is a possible 
cause as well.
Disconnect everything from the K3 except power and the antenna and power 
it on.  Replace things one at a time to see which brings the problem back.

73,
