107.9's signal is pretty lousy in much of the western end of the metro. If you live in Lakewood west to Lorain County, or southwest down toward Strongsville and Medina, their signal sucks. Around the heavily populated areas of Parma-Parma Heights-Brecksville, they get clobbered with interference from all of the big Cleveland FMs who broadcast from the towers which are right there. Ride up I-77 near Rockside and try to get them clearly. Forget it. That's why Power 108, The End, and other 107.9 formats which needed full market coverage failed.
107.9 never had a winning format until Urban.
That's because the high-density black areas of East Cleveland, Warrensville Heights, Beford, etc are all within 107.9's strong signal coverage.
They don't need a full-market signal to get big numbers with an urban format. Hell, WJMO on 1490 AM used to be one of the top rated stations
at night with their black format......and they had 250 watts are were not heard clearly beyond about 8 miles after sundown! But the whole audience was right in their back yard, so it didn't matter.
