Four years ago I posted about an unidentified 400 mhz P25 system, at the time it was a Phase 1 system. Not being in the area to monitor the system very often I kind of forgot about it. Today I again heard it and apparently it has been upgraded to a Phase 2 system. There is very little traffic on the system and users are able to make private calls from radio to radio. I've still not ID'd the system, but am leaning towards a second Durham VA system due to the similar NAC 841/System ID BEE00.845 with the known Durham VA system BEE00.8B9 NAC 8BO. Any help in IDing this system will be appreciated.

System Information is:
System ID : 845
WACN : BEE00
NAC : 841
Tower Number (Decimal): 1-1
Tower Number (Hex) : T0101
Control Capabilities : Voice,Registration
Flavor : Phase 2
Timestamp : Tue Jul 14 14:12:45 2020

I wrote about this system in the July, 2019 issue of The Spectrum Monitor magazine, and received information that is belongs to the National Institute of Environmental Health, part of the National Institutes of Health (NIH).

163.1375 $293 is 100% the USCG CG/NET-113
just looked through the thread and saw:

406.550 ($315) ONLY ENC, RIDS 1XXX,
163.1375 ($293) USCG?,

anyone nail those down? totally new to me. do they appear limited to KRDU actual, or just the RDU area?
