First post on the forums after learning most of what I know about scanners and radio systems through the site in the last 6 months or so.

Had the 996p2 going on close call in the truck the other day on campus and picked up some sort of digital voice that it couldn't decode from a repeater about a block away. Looked up the frequency (UHF) and it's one of many in my university's FCC license.

Since I also work on campus and am around radio users (Public Safety, facilities etc.) I've noticed they use some sort of MotoTRBO business-style radios, which makes me think it might be DMR.

Thinking they are using conventional vs trunked but am not completely sure given the number of frequencies they have licensed and the fact that there are side tones (or wait tones) programmed into all of their HTs.

Anyone have any insight into what voice this is?

ULS License - Industrial/Business Pool, Conventional License - WPMX610 - DEPAUL UNIVERSITY

Emissions Designator will usually tell you all you need to know.....

Looking here under the frequency listing we see the Emissions Designator of "7K60FXE"...

Now look at the RR Wiki Emissions Designator page here:
Emission Designator - The RadioReference Wiki

7K60FXE is 2-slot DMR (Motorola MOTOTRBO) TDMA voice.

It appears as though you have a MotoTRBO DMR system to map out.
