Hi Jake,
Here's what I found on the Rutherford County NC database....
Sheriff Dispatch 154.845
Fire Dispatch 159.195
EMS Dispatch 155.055
Jake, as I mentioned in my last post, Bostic is probably handled by the county since it is a small town. So they may not have their 'own' frequencies for their own 'tactical' use unless someone else from around that area knows more than I do other than what I see in the database. Hope this helps you and glad to help when I can. Have a good night and enjoy your monitoring.
