[Elecraft] KAT500 Power-on yields K3 into XMIT

[Don Wilhelm]

Bob,

Somehow, somewhere, either the key or paddle or PTT is closed - at least 
the K3 thinks that is true.
You might first check visually to see if you can find the culprit. If 
not ---

Remove the mic, key, paddles and your interface from the K3 - then with 
K3 power on, plug them in one at a time.  If any of them cause the K3 to 
go into transmit, you have found the offending one.
