Got that...curious, NAC change must impact subs on the system/site. I would assume every radio for that site would need an update. Only way to accomplish this must be OTA? Curious as it sounds like PIA.Primarily to avoid co-channel interference when frequencies are shared/reused at multiple sites within the same system. Some systems, such as STARNet, make it a habit to assign a different NAC to all neighboring sites, even if no frequencies are shared. STARNet is using all 16 variations of the NAC related to the 942 SysID, i.e. 940-94F. It appears that NJICS is now starting to do the same in some instances, whereas previously most of the ASR sites were 390 (and still are mostly), and the simulcast sites used 390-395. Now we're seeing 39A-39E in the mix.
