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?

Instead of using an intial time delay, why not force the K3 to wait
for a high-to-
low transistion on the key line before it first transmits?
