How do you find the active frequency on an FCC license?

[ZacharyF]

I'm curious about how to find the active frequency inside of an FCC license.

FCC license frequencies look like this


So, how do I get the active frequency, do I just have to scan all of them until I find the correct one? Typically I'd just look up organization on the RRDB, but obviously, not all orgs are going to be displayed there.

I suppose someone on here would have some experience doing this!

the only to find out if there is any activate on of those freqs is to listen to them.

Not all frequencies on a particular license may be broadcast from the site nearest to you. Look up, and cross reference locations as well.

If you pull up the license on the FCC site, click on the frequency tab, and you can look at the Station Class column. The ones marked with FB# are the repeater outputs. The ones marked with MO are the mobile/portable radio transmit frequencies, and sometimes used for simplex (radio to radio) use.
For most people, the FB# repeater outputs are the ones you want to listen to.
On the Frequency tab, you can click on the individual frequencies and it'll take you to a page that will show you the emission designators for that frequency. That'll help you understand if it's analog, P25, DMR, NXDN, etc. You'll need to translate the emission designator to a plain English explanation here: Emission Designator - The RadioReference Wiki

If you click on the "Locations" tab, it'll tell you where the radio sites are.

You will have to scan them all, or, as suggested above, scan the ones with a FB station class code. Most entities license more frequencies than they really need for "future" use.
