Was doing a search and found 409.2125 NAC 2B5H. Database has this as Atlanta BOP analog trunked system. Did they go digital? Would this NAC correspond to them?

edit: just realized I read in the database wrong that they're digital-I guess I don't recall ever hearing the system before

2B5h would be the correct formatting for one way of posting where the lower-case "h" indicates HEX
also some folks use a prefix of N for NAC or a "$" Dollar sign but $2B5 is a correct NAC for them for years.

for the OP
Many of the FBoP systems run a legacy [Type II] TRS with P25 Voice
if you drill down into the Zone/Site you will find the NAC has been there


I'm not familiar with this particular user or system but "2B5H" is not a valid NAC.

I was able to listen more today and All the talkgroups appear to still be in use and all digital. Thanks for the insights!

As a Motorola Type II or P25?
I may need a little help determining that I guess. I was using a BCD-536HP. When I made the post, I was doing my usual custom search of the UHF gov't band and that's when I heard the digital transmission with the NAC displayed. The control channel sounds like data from a Motorola Type II. Today I just scanned it in trunking mode and all the talkgroups that are in the database were in use. What is a way I can tell for sure if it's P25 or Type II? I went to checkout PRO96 com, but I don't have any of the radios supported

find the Control channel and see what the System ID being broadcast is.
4 Character with a Connect Tone is the legacy Type II systems
3 Character with a NAC is a true P25 system

So I realized my SDS-200 shows this easier, but today the signal is very weak. Not sure what happened, but the past couple of days it was booming in here, now I can hardly hear the control channel. I've tried 2 radios and 2 antennas. I'll update if it comes back, though.
