Check out the Campbell County Database page. It looks like they restructured their frequency assignments. They now have North (453.050), Central (453.800), and South ( 453.575) Primary frequencies, where I believe 453.050 was just Newport and everything else was CamCo. This is different from what I had programmed in my scanner, so I assume this is a recent change. I don't get home much anymore.
According to the feed info - Bellevue, Crestview, Dayton, Highland Heights, Southgate, Ft. Thomas, and Wilder are on the Central Frequency. Probably Newport still on the North, and I don't know who would be south.
The county had an EDACS system they used for car to car comms, I would give it a listen too.
