Reference the two Input and two SO-239's on the PowerGenius XL. When one set of in/out SO-239's are active, are the unused set of SO-239's being passed through? Or are the unused SO-239 in/out connections just open?
Passed through. It basically wants to behave like two amplifiers that can only produce one signal at a time. But you can TX on one while RX on the other for true SO2R.
