Using the Arcom RAD board, single delay for all inputs, hence

Not got those jumpers, it's the earlier RAD version.

they don't, you cannot combine them
Of course this presumes each radio can supply enough level. If not
you'll need something like a summing amp (using an op amp is the
easiest way to implement this).
The RAD expects 1 volt p-to-p max do don't overdrive it.
