You might try WLIL 730 AM out of Lenoir City. It might come in a little weak, but they play mostly classic country. In the weekday mornings at 9:00, you can tune in to the "swap shop" where you'll find anything from hogs to guns for sale....pretty interesting sometimes.
If you want to hear the real stuff you're gonna have to get a XM satelite radio. "XM-13 Willie's Place" where you get all that good stuff out of Texas.
