If you are talking about the QRV one (the one that we put out) then you only need 1 per system regardless of whether its half or full duplex. As far as the French one goes, if you were going to use it for full duplex, if it even works that way, which I guess it should if you hook them up correctly, then you would need 2 of them for a single full duplex system.

I'm about ready to build some arib boards. the question I have is how many? if I have a port I'm using as a remote base it seems obvious that I should only need one, but if I'm using 2 ports in full duplex operation, haw many boards do I need?
