410.3250 MHz Tucson

[ChrisP]

Can anyone in the Tucson area take a listen to 410.3250 MHz? This is a new one for me.

It is DMR with a color code of 05, but doesn't appear to be part of a trunked system. It is fully encrypted however.

I suspect it is the U.S. Postal Service (not Postal Inspectors), probably a sorting or bulk mail facility, because it's been busy 24-7, and lots of long conversations. From my experience that sounds like mail sorting. But it is unusual that they have enabled encryption.

The frequency is a USPS nationwide assignment, but a few other agencies have assignments to that same frequency.

Thanks!

I listened to this frequency over the weekend. There was no DMR activity. I noted today some P25 activity. I plugged it in as P25 and got about 10 talk groups to pop up right away. I think it's the Tucson Federal Correctional Complex south of Tucson. The NAC was BA1h. The frequency is not listed in in the data base as belonging to the prison.

Interesting - I have many recordings and what I heard was definitely DMR, CC5. I was listening on the northeast side of town, near TMC.

That is interesting. I guess we are neighbors.
