FCC Class_Station_Code

[RexHuntC]

The FCC maintains a 4 character Class Station Code and a description of what it means. There are 13 that refer to Trunk Relay something or Trunk Mobile something. It's located in FR (frequencies) tables. I was wondering which of the trunk type frequencies would get me hooked up to unknown trunking setups on my Uniden SDS200? Any ideas?

Normally they are 2-3 character Station Classes

You are generally correct however sometimes the FCC places a suffix (a 4th designator) at the end. Interconnection to the public switched telephone network (PSTN) first comes to mind. So a FB2, mobile relay station with interconnection to the PSTN becomes FB2C. Another would be a temporary location station, such as FB2T, FXOT (operational fixed station at a temporary location) etc.

correct, however I was taught those are modifiers or a Suffix
T = Temp
I = Itinerant
C = Phone Patch or interconnect

concentrate only on the FB2, FB4, FB6, FB8 series those would be Repeater Outputs
anything else would be useless for a scanner for trunking as they would likely be inputs or control stations.

Do you have a specific License to reference ?

I am a retired computer programmer and years ago I put together a dot net app using Visual Studio and SQL Server using the FCCs public access files. Lately, I wanted to update the database and I realized how much I had forgotten over the years. The SQL part came back quickly but the dot net not as much. I recently bought a Uniden SDS200 and got interested in trunking. I added a "trunk only" checkbox to the dot net program and I was using all the codes that had the word "trunk" but now I think I'll pare it down to the codes you mention. The app lets me search on state, county, and city along with pre-defined frequerncy ranges, custom ranges, or individual frequencies. For Bloomington, IN I came up with B&L Communications (three call signs), Electronic Communication Systems INC. (two call signs), Emergency Radio Service, LLC (two call signes) and Indiana University Campus Bus Service (one call sign). I still have a few glitches with the new checkbox but that's all part of the fun.

Also keep in mind, altho licensed for Conventional, many have found users/agencies trunking and others licenses as trunking have been found as conventional for some frequencies.

Happy hunting

There is also the State of IN SAFE-T Trunked Radio System site near Bloomington. (Licensed under the IPSC) Its P25 Phase I, 7/800 MHz, in use by pretty much every Public Safety agency in the area. IU and ERS are both DMR formats.
