Fayette county uses a rebanded Smartnet II 800MHz analog system currently, so any recent analog trunking scanner will work, you will have to load the rebanded frequency tables.
They do plan on replacing this radio system in the next 2 years from what I heard at a GEMA interop exercise, most likely with a phase 1 P25 digital system, but are like everyone else, working on securing funding to do so. Motorola ends support for Smartnet II at the end of this year.
So keep this in mind if buying a NEW scanner, you might try to find a used Trunktracker analog, just make sure it's not a really old one that won't do rebanding.
