Charlie, how this could work after there is no way the TX Inh inputs
to be pulled down?

Look at:

I belive it's different than the one you described in your email.
I've
used this one successfully.

Hi All
I don't like re-inventing the wheel, so I'm looking for a design to
copy!
I'm looking for a circuit to interlock two K3 so they cannot
transmit
simultaneously. I am aware of the simple connection cross linking
the
PTT out and Inbibit input on the 15 pin connector. That does not
meet
our needs as when both try to transmit - both are inhibited !!
TIA
