Whenever I search for FCC data, if the frequency is in the 454.0000 - 455.0000 range, I never get any results, even though I have several active frequencies in that range. For example, there's a hotel on 454.125 and I'm trying to figure out what hotel it is. We have a Hillsborough County School Board frequency of 454.6500 that is part of a DMR system used by school busses. Neither one brings up any results on RR. Does the RR FCC search not have this frequency range available?

454 MHz frequencies are covered under CP Part 22 VHF/UHF Paging or CD Paging and Radiotelephone licenses. They are licensed in blocks of frequencies for a geographic area, and are usually not site or frequency specific. The licenses do exist in the RRDB, they're just extremely vague because that's how they are in the FCC ULS.

You need to use the FCC ULS to search for these licenses. For example:

Is there a similar issue with frequencies in the 173.xxxx range? I have a few that I also can't find results for 173.050, 173.810, and also 164.010. They all use DCS 023 and sound like a security company with a dispatcher.

Those are all federal government frequencies. There is no public database for federal licenses.
99.9% of frequencies in the 162.0375-173.2 and 173.4-173.9875 federal band are on 12.5 kHz steps. 173.81 and 164.04 are really 173.8125 and 164.0125. I don't know what agency those and 173.05 belong to that would use analog DCS instead of P25.

As Tom, indicates no, the 162-174 with some exceptions are NTIA Frequencies and there is no Public Search available, however sometimes you may luck into an FCC Search, with many States now having access to that band for Statewide Trunking when they can show the need due to limited Part 90 available Frequencies. Some even have been given Railroad frequencies as well.

Also within the 162-174 there are some Public Frequencies.
Paging, Wireless MICS, Telemetry, and Relay Press


BTW 173.8100 is invalid

There is some DMR activity here in Jersey using the 454MHZ band,I doubt its government.....
Sounds more like a lawn service or a DPW.

Go to
FCC General Menu Reports 3.1.14 October 7, 2010 click on Site/Market/Frequency
Site / Market / Frequency Query Select NJ and then select Service Selection
choose "Specific Services" and check off Paging
then select Radio Service Selection, select Specific Services for Paging.
Select "CP - Part 22" and then run your inquiry. :cool:

The 454 and 459 pairs were auctioned off as Part 22. You will either find commercial services there or private licensees (public safety and business) who are leasing the channels. The top of the band contains air to ground telephone channels which were active when I last tuned in. They can be most interesting. I heard some big wigs discussing a contract to sell helicopters to a south American country once.

Worked for me with the example and it was just an example to use NJ

Maybe FL you might need to also select CD [returns Plenty]
even tried GA thinking a wide market area, but GA returns GA and AL

Guess the FCC wrote FL off.
And how come NJ and not FL?

Florida probably did not need the spectrum and/or nobody down there bid enough to acquire it.

As far as I can tell bidders bought the auctioned paging spectrum in every market area in the country.

I posted the licenses for the OP's frequencies. He is doing something wrong if the FCC search page doesn't show any licenses.

Tom getting the FCC to work for most states, except FL which returns NO Records.

So not just the OP

That geo search feature is buggy. You have to start anew, refresh every search. If not, nothing is found, and most likely the FCC server ignores the request.
