No, this is for one radio only.Are these inputs connected to two separate radios that do not have a common ground?
The select voltage levels do not change between Rx and TxAlso, need to know if the SEL voltage levels change between when there is no traffic (not transmitting) and traffic (transmitting).
Sorry i forgot, the FM, SSB\CW select lines are +12v dc from a ULN2981A chip (But at the moment from a 1p 4w switch for testing)I don't know what the levels of the signals are that you are putting in on the various SEL lines
