Have you checked the data base for Tolland County? That is pretty good and if you are looking for specific towns that are not listed in the database put up a post looking for those.
Use the FCC website and research the TN listings http://wireless2.fcc.gov/UlsApp/UlsSearch/searchAdvanced.jsp
and put 0005046297 iin the FRN line. Then look through every result and see the freqs and locations. Then repeat that for each town that TN dispatches so you can get the frequencies that the individual departments are licensed to use.
Another reference is the archive search here and on Connscan since it seems that similar info has been requested before. It was also asked on Fordyces site before that shut down.
Save your results for future reference.
