East Tennessee: It's tough to answer because there is so little I've gotten more than once. The Florida catches I've gotten in Ohio seem just out of range in East Tennessee. (no Tampa, Orlando, Winter Haven etc) but I've gotten Southwest Florida a couple of times. The Bahamas, Cuba, and the Cayman Islands have found my car radio. I've gotten Texas (Dallas and Houston areas), Wyoming, Montreal (which might be my most frequent), even Prince Edward Island. Best tropo: Tropo is rare here, most frequent is WGTZ, Eaton, OH and WFCJ, Miamisburg, OH.
Ohio: A lot of Florida, Louisiana, Texas, with some Colorado and Wyoming.
Most frequent station both places: 93.9 KSWN, McCook, NE
