Is there a place where I can find out what a frequency is for our county's maintenance precinct radio's? I need to add it to our city radios, but none of the county workers knows what it is. I cant believe they dont have any records on file or who would have those files.

You might talk to the local cop shop and fire departments.  Other than that, it might take a scan if you can narrow down the band.

I have a frequency counter for that,
just get someone to key up the radio near it and it tells you what it is (or at least the input of the repeater, but it is not hard to find the output from there)
at least one of the yaesu handheld radios I have can do this a section of a band at a time, would take more time, but might still work

can you get a look at what radio they use ?
if so, you can go look it up and at least find out what band it is in.

I keep my counter in my car in case I see someone transmitting and have it connected to a mag mount 2 meter antenna.

Our city and county work together to do seal coat on our roads. Im having the city rebuild its radio  network. For a long time now cell phones replaced the radios. As new trucks replaced old trucks, They just didnt put radios in them any more. Our city ( Ft.Stockton, Tx. ) understand's what will happen when the phones stop working and other disasters that could happen. The city is prepping. Plus it was just time we started using radios again and git rid of allot of cell phone bills. Our street dept. needs to be able to talk with the county workers in there trucks. I think whats happen here with no one in the county having know idea what there freq. is, Is that in the past all there radios were leased to them and only the radio co. know's what it is. All the old workers that knew are gone now.

there use to be books that were sold for people that had scanners, they had every FCC license for your area,
each department was listed with the frequency, someone might have an old copy lying around
the big problem with them is they listed everything, so it was hard to tell what had activity or not

can you find it in here ?

What's anyone recommend for a 12V compact scanner that will pick up the trunked systems?

This ^^

Radio Reference is amazing. I use it all the time. As BT mentioned, there is also the FCC database.

None of this information is secret, but sometimes it can be misleading. For example, if an agency leases their radio system, the license may be under the lessor's name. Or a business may be using radios licensed to a parent company that you don't recognize.

Sometimes there's a little guesswork, but it should not be that hard to figure out.
