It would appear that STCC is running an 800 MHz DMR TRS.
854.0625 Control Channel DCC0
856.1375 licensed
859.1375 licensed

Supposedly, and this needs to be confirmed first hand. (The source that told me is very accurate however)
STCC is actively using this trunk.
Campus PD are encrypted.

Wonder if they also have a TG for the NPS [Armory] or did they stay Analog

It is very active but unfortunately, the DSDPlus program doesn't work on it so I haven't been able to figure out the trunking layout. The signal is very strong and can be heard 15-20 miles away.

My 436HP showed the following on 854.0625
CC:0 NET12 XPT
No other comms on the other frequencies, but on the weekends, the campus PD tends to be quiet.

Last time I tried to monitor that system, there was a continuous Control Channel running. XPT is intermittent like Capacity Plus.

On 859.1375
TG 1642213
CC: 0

Security officer : Asking for dispatch times for the report.

Unsure if this is Armory Security, STCC Security, or another user.

OK some TG conformations from today

1643544 is Campus Maintenance. (Respond to water leaking in a room, issues with lights in another room etc).
1642213 is Campus Security (Respond to Lot A for a woman loitering. Unlock a room call etc)
1644875 only keyed up for a brief moment
1656858 was an encrypted TG
1656854 appears to be simulcasting the Northampton SP barracks for a little while but then stopped! (B-PTL-1)

With the latest version of DSDPlus, I was able to Trunktrack the system. I added the DSDPlus Channel numbers to the WIKI however, this is a DFA system. The frequency information gets transmitted like P25 systems. All you need to do with DSDPlus is to set the FMP24/FMPA onto the Control Channel and it will populate the window and trunktrack. This seems to be a DME feature that Hytera systems use.

I have had no luck getting Uniden DMR capable scanners to work with these Hytera Tier III systems, . The standard DSDPlus to Uniden channels/LCN doesn't work.

No encryption noted but there was one frequency that had a bit of interference when it was used. If I was closer than 17 miles, perhaps it would have been clearer.
