To Be Identified DMR

#1 Post by ecps92 » 14 Feb 2020 11:25

While attempting some Long over due College confirmations, I am getting [Analog only radios]
some DMR data bursts on 463.4375, the College is still Analog [Per FCC, and other active channels in the license]

Looking over the Boston area Licenses, I have narrowed it down to two suspects.

Industrial/Business Pool, Conventional License - WQJH638 - RENAISSANCE HOTEL OPERATING COMPANY
https://wireless2.fcc.gov/UlsApp/UlsSea ... e=&x=3&y=2
or
Industrial/Business Pool, Trunked License - WQAA254 - JETBLUE AIRWAYS
https://wireless2.fcc.gov/UlsApp/UlsSea ... =&x=10&y=6

Might be worth looking at, for anyone with a DMR Scanner

Bill, how often are those bursts coming? I've been monitoring that freq for the past hour on both Airspy/DSD+ and 436HP, and haven't heard anything in Burlington. (Well, one scratchy analog voice xmission, but no DMR.)

I have it listed as part of JetBlue's Tier III system. It was listed a few years ago as LCN 1076 but I haven't recently reconfirmed.

Hello,

Hopefully I will have time to listen since I can pickup the JetBlue Tier III System.

One thing I noticed is the voice transmissions on their system (at least) look like conventional DMR. So different than Cap+ and Con+.

I also sometimes have them show up as conventional DMR when I listen on my SDR, though on my 436 they pretty consistently display DT3. Someone was kind enough to post the frequencies and LCN orders a few years ago, if you don't have them I'd be happy to share them with you. I also have a running ID'ed talkgroup list if you'd like that as well.
