Anyone for NAC's?
I've been getting some requests from readers for information about the federal use of Network Access Codes or "NAC"s on P-25 digital channels. So far there are few ways for the monitoring hobby to actually read or use NAC's, but since CTCSS or PL tones are going away when radio channels turn digital, maybe a pattern of NAC assignments by particular agencies will reveal itself.
If you are able to decode NACs on federal P-25 systems, consider starting a federal NAC database here at the Fed Files!
