I did a 800 mhz search and it stop on a freq and 3 digit pop up. For example 317 will show up when they talk. I do not know what that is.
317 (decimal) = 13D (Hex). Could there have been a typo?I try to search for the P25NAC see the numbers like the pl/dpl tones. I do not see 317 on the list I see 31D on there.
The scanner does show the NAC in hex. On trunked systems, the site's NAC is usually a subset of the SystemID. In Michigan, on the MPSCS, the System ID is 796 (Hex). NAC values always start with 79, and vary from site to site on the third character (Local towers are 79D,79A, 79B, etc..)317 (decimal) = 13D (Hex). Could there have been a typo?
(Unless the scanner shows the NAC in Hex to start with, then I'm out of ideals.)
