Just some thoughts, mindya.

A reasonable implementation would receive PTT key signal, wait some
time to let the relays settle, verify that the relay contacts are all
in the correct positions, and then key the appropriate transmitter.
That guarantees that the race is won by the relays. This type of
circuitry would be relatively simple for a $700 product. Is that
what's done by Comant? I don't know for sure, but I would hope so.

I did, however, answer Nick's question. If he or his friend are
interested enough to pursue an informed answer, he can call Comant.
