I live in a complex in San Jose, CA that is patrolled by a company called Bayside Patrol. Their guards have two way radios on their belt. I can't find an FCC license for them or anything on cityfreq.com.

Without an FCC license, I suppose they could be using MURS frequencies, but their headquarters (and presumably dispatch) is 10+ miles away, so I don't think that would cut it. Any other license-free possibilities?

I think I need a frequency counter...

Could be itinerants, MURS, GMRS licensed as a sub-company or they could be renting access on a local GMRS repeater.

Hm.. ok. I've been scanning the GMRS & MURS freqs and haven't heard anything. What do you mean by 'itinerants'?

Other possibilities

They could be renting airwaves spaces from a comms provider.
There are several LTR systems I listen to that have diverse traffic because it's a 2 way radio service. Open Space Rangers, Dogcatchers and dumptrucks on the same commercial system.

Look for LTR or other commercial systems in the area.

To expand on what NW0U said, they could be leasing space on a commercial trunked system, LTR or otherwise. If this is the case, you won't find them in the FCC database, because the end users of trunked SMR systems don't need to have a license.

Another possibility is that the license is issued under a name that wouldn't be obvious to someone searching the database. For example, there used to be a local septic tank company called, "Johnson Septic Tank Co.". They used two way radios, but their license was listed under "F.A. Johnson, Inc.". If you didn't know that F.A. Johnson was Johnson Septic Tank, you might easily overlook them in the FCC database.

Yea... our whole fire department is under our part time Lieutenants name here... so good luck

Other way to do it from what i have heard is put your scanner on the close call option if you have it and you might find it there.

Eyeballing the antennas on their radios could also give you a bit of direction as to what the frequency range they are using is.

Understood. There are surprisingly few trunked systems in this county:

It doesn't have that feature.

Why not just ask them for their frequency? If someone asked for ours, I would give it to them, though nothing interesting happens. Other then that, just use a scanner with close call and see what happens.

CVPI... unless there are beach patrol guys like us, they are going to have no idea. Where im an explorer at, i know alot more about our radios and what frequencys we use more then the firefighters do. Just an idea... but i dont think that one would work.
