Do the radios have RX antenna inputs/outputs?
If you use radio 1 for transmit, connect the RX out to a 3dB splitter (e.g.
Mini-Circuits) and one output back to RX ant in on radio 1 and the other to RX
ant in on radio 2. Put the TX antenna port on radio 2 to a dummy load just in
case. That way you have your TX ant for receive on both radios, albeit with 3dB
loss but not a problem on HF.
You only need to have some sort of audio switching now.
Does that help?

Assuming you don't want to listen and transmit on the same band with the same
antenna at the same time -
You would need some sort of interlock device and a splitter.
A much better approach is to use a SDR with two virtual receivers.
Flex-6000, Anan, Elad, or even a Softrock would fit the bill.
