I'm going to preface this by saying I know very, very little about NXDN.
The last several times I've visited the Riverbanks Zoo in Columbia, their UHF analog frequencies haven't been active, and I noticed staff carrying what appeared to be NXDN handhelds. On my last visit I monitored the FleetTalk Carolinas system thinking that perhaps they moved to it, but I didn't hear them on it. Before my visit yesterday I searched the FCC database and found a license for the zoo that looked like a NXDN TRS. I programmed the frequencies in my TRX-1 as a NXDN C system and left it in the car to log/record while I visited the zoo. Earlier tonight I went through the recordings, and this is what I found:
Riverbanks Zoo NXDN TRS (WRTJ989)
461.44375, 461.76875, 462.06875, 462.73750
462.5375 listed in license - in use as control channel? (need to check on my next visit)
TG 35151 - Public Safety?
TG 35152 - Zoo Keepers
TG 35153 - Maintenance
TG 35154 - Unknown
TG 35155 - Tram
TG 35156 - Unknown
TG 35157 - Unknown
TG 35159 - Housekeeping/Groundskeeping?
TG 35160 - Unknown

Perhaps someone local in Columbia (and with more NXDN knowledge than I have) can give it a listen and figure out more about it.
