Site 167
Looks like this is some sort of a special or test setup at the
State Denver Transmitter Building (DTB) 4201 S. Arkansas. Denver
They have a pending modification to the DTB license to include the following 3 frequencies:
853.7375
852.7625
851.325
These are additions to the existing license, but are listed as being only 10 watts ERP
The attachments to the license for short spacing use of two of those frequencies list them as only 5 watts ERP. The antenna for those 3 frequencies is listed as only being 4 meters in elevation, and 3 dbd of gain.
(the other frequencies that are part of Site 120 are 158 watts ERP, 39 Meters in Elevation and 9 dbd of gain.)
The mobile use is listed as a one mile radius of the DTB.
One of the attachments labels the site as "167 - DTB Test"
What ever the purpose of this system is (probably an in building system) it's very low power and you'll probably have to be on a nearby street or in the parking lot to hear it. Given the limited number of voice channels - 2, the users are probably going to be a pretty small group, and their TG would probably need to be blocked from the 120 site. (or it's purpose could be to test some other new functionality in the system). That address is the CDOT building, and the state Denver radio shop.
