Have you already looked in the RRDB at the county page(s) were you live? Click on the link at the top of the page called "RR Database", click on Missouri and pick a county.
If you have and there is not any information you can also use the RRDB to search for clues.
Go the box on the main RRDB page titled "FCC Data Queries" and drop the box down beside "State/Frequency" and choose Missouri then type in a frequency.
Using the first frequency in your list of 154.325 ... most of the results returned show that it is tied to fire departments. As always, if you solve some unknown frequencies, please submit them so that it can be included in the database.
Only problem i found with that is, it's hard to tell sometimes what the freuqncies are being used for.. ie, one frequency might show "lawerence county of" well, does that mean, sherriff? ems? fire? so that's why i'm hoping people in swmo will know these frequencies and tell me the what they are.
