• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

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?

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.
