East Tennessee: Depends where you are, in Knoxville generally only iBoc hash from 104.5 WKHT, in Sevierville and Gatlinburg it's WLNQ, White Pine TN. Clingman's Dome brought in The Fish from Atlanta.
Retro/other: Dayton, Ohio is local WTUE. Once in Springfield, OH I managed to get iHeart sister WIOT, Toledo, carrying Bob and Tom a few seconds after WTUE.
Since the mid-70s, both WTUE and WIOT have been AOR, then Classic Rock no matter the ownerships. The WTUE/WIOT line is Lima or Marion, Ohio.
Lafayette IN area was either WFRN, Elkhart, WCFL, Morris, IL or WTUE.
