[App_rpt-users] simplex vs duplex for a home node

[Elden Fenison]

Iain, you make a good point. In my situation, it's probably not worth
doing. It is kind of nice to know if you're doubling with someone however.
But yeah, even if I have a dual-receive node radio... my HT or whatever
would also have to be capable of being able to listen and transmit at the
same time. I was just curious how people do it. It sounds like I would need
a repeater for the node and of some kind of dual-receive radio to talk to
it on that can receive while it's transmitting. That sounds way too spendy
just to avoid doubling.
