Any one in the Metro area have a signal on 851.8875? I'm getting it full-strength on a PSR-500 here in Thornton and it sounds like some type of data. I still get it very weak with the duck off altogether, so I'm guessing its fairly close to my location.

A search here reveals only DTRS licenses - none near the Metro area. I'm not sure how to search the FCC database...

I was conduting my own thread discussion :lol:

Hopefully someone more educated than me on Denver's reband will pipe up and tell us why Denver didn't re-band the MDT system.

But it still leaves my original question regarding 851.8875 as a nagger...

My guess is that it's the Dataradio system:

Dataradio Inc. Wins Contract to Provide Mobile Data Communications Network for the City and County of Denver, Colorado
03/25/2008
CalAmp Corp. announced that its Dataradio operating unit has been awarded a contract with the City and County of Denver, Colorado to construct a mobile data network to be used by Denver's law enforcement personnel. The contract is initially valued at approximately $2.3 million. Work on the project is expected to begin immediately with system acceptance scheduled for the latter part of calendar 2008.
Similar sounding data can be heard on: 851.1875, 851.5875, 852.125 and 852.65 (old channels 21-24 on the public safety voice system).

While researching this, I came across the Denver EEB home page:

Electronic Engineering Bureau - Welcome Message

Has anyone seen a license listing for the new frequencies? I'm guessing the current 860 freqs will remain until they convert all cars to the Dataradio system?

KNNR200 is one license where the frequencies I mentioned, as well as 851.8875, exist.

Knnr200

So, I decided to do some looking at KNNR200 and comparing those licensed frequencies to the known 800 MHz frequencies in Denver Co. (trunked and conventional). Here's all the licensed (but yet unidentified) frequencies in order:

851.5625 *No signal* (Also licensed for CO DTRS)
852.3750 *No signal* (Also licensed for CO DTRS)
852.7750 *No signal* (Also licensed for CO DTRS)
853.1500 *No signal* (Also licensed for CO DTRS)
853.2750 *No signal* (Also licensed for CO DTRS)
853.4250 *No signal* (Also licensed for CO DTRS)
853.7250 *No signal* (Also licensed for CO DTRS)
853.8625 *No signal* (Also licensed for CO DTRS)
