I'm not sure they will be on Moswin Terry other than the normal All and Travel type listings but who knows.
First, I'm out of range unless I travel so I'll likely not be much help on this one anytime soon. But... looking at Washington Counties two primary FCC licenses for WRPB788 and WPWR986
WRBP788 (WASHINGTON COUNTY CENTRAL DISPATCH 911) FCC Callsign Details and
WPWR986 (WASHINGTON COUNTY CENTRAL DISPATCH 911) FCC Callsign Details
It looks like they requested new or modified licenses for both back in 2018 or so that Adds about every common Emission type used for LMR!
I did try getting signals from a few of the listed frequencies but heard nothing so far to confirm if they are NFM, DMR, P25-P1 or P2 or NXDN going by their license's permissible emission types so it's anyone's guess.
The licenses almost look like they are setting up a countywide VHF trunked system using four tower sites.
I know we have users in that area of the state so maybe somebody will chime in with updated info or better yet, do a user submission for the RRDB. If you look at the license data, it sure does look like a change to one of the digital formats is in the works or has been completed.
EDIT: While typing, I did pickup WRBP788 on 154.860 in Analog NFM mode which is listed as Washington County Sheriff Disp 1. The traffic and locations heard confirmed that as accurate. Possibly an analog simulcast of a digital signal I can't hear or maybe law is still analog while fire/ems has moved to a digital format. Who knows!
I can copy Moswin traffic from that area and have not logged any unknown talkgroups indicating anyone in Washington County is using Moswin.
I'll keep an eye out for that.
