+1 buy from EvansI have a supply of FPP licenses for the nx line.
I'll answer my own question, now that I am back at home.Don't know. I don't use FPP on any of my NX-5000's. That sounds like an Evans sort of question. I suspect that since the FPP is technically only a "federal" feature set, that it will stick where you put it. In other words, the dude poking at the radio is expected to know the rules and do things correctly. If everyone was following FCC rules, FPP wouldn't be available as widely as it is.
That would explain the complaint of quiet audio.
