Site 220, 267, are your primary sites for Knox County. For complete coverage, you also want the surrounding sites. 223, 261, 269, and there are others but I would have to dig deeper to get them all again. Remember, program as Motorola, without the rebanded tables, and CC only, with a plain FM freq between the sites. Same as you do for an PRO-96. in fact, I can set up an ARC96 file or Win96 file for Knox County area SAFE-T for you if you want to play around with it.
