Hi Simon To work through what you want, I'd put together some kind of Boolean algebra table. So you could say TX1 = (NOT TX2) + (NOT TX3) and so on. When you are done, you have defined a relay switching network that can do the job for you. You will have to decide how to tell the system which TX you want to use, perhaps F keys on your keyboard. Then you have to get those commands out into the relay system. That I have to leave to you, as I'm not much of a computer person. Good luck and 73 Bob N6WG

You would only transmit with one radio, the others being used as high-class receivers, spares etc. How would you route the antenna? What I want to avoid is transmitting into a receiver by accident if the software decides that it would be good to switch to TX. FWIW I am looking at two K3, one TS-480SAT. I would like to receive on all three simultaneously and transmit with either a K3 or TS-480SAT.
