This is another way of describing what I'm proposing, John. If /KEY is 
found asserted anytime during the 2-second power-on sequence, the K3 
might show "ERR KEY" and prevent TX until the line as been released. If 
re-asserted anytime after that, the message would go away by itself, 
and TX would proceed normally.

I can catch premature /PTT assertion, too. So there would also be an 
"ERR PTT" message. Same logic.

Sound OK?
