East Tennessee: In parts of the area, W255BK, Newport, TN. Otherwise 98.9 is a pretty clear frequency, with WSPA-FM, Spartansburg, SC being there if anything for the most part. I've also logged WSIP, Paintsville KY.
Retro/other: I have worked at a 98.9, WBYR, Fort Wayne, which celebrated its 34th anniversary in January. I was pleased to be on a Zoom call with alumni. Of course, the station itself has been on a lot longer than that, as WERT-FM, running much lower power than the 50000 watts it has now. WBYR has a tower in the town of Arcola, IN and the COL is now Woodburn, IN. The signal reaches seemingly forever to the East and still has regular listeners in Lima, OH. I'd get calls from parts of Michigan on weekend overnights, and in the 90s,could frequently get it in Lafayette, IN. Otherwise, WSLM-FM, Salem, IN would reach the Lafayette area.
In Dayton OH 98.9 was difficult with powerhouse WHKO next door on 99.1, but I got WBYR frequently and occasionally WSIP.
