Getting back to the original post, it was only a .1 win, but it is amazing that low power WNFN beat Class C WRVW.
WNFN 106.7 Millersville....Midwest....15,000 watts....278 meters (912 feet)
WRVW 107.5 Lebanon....iHeart....46,000 watts....409 meters (1,442 feet)
WNFN has been a Top 40 station since 2009 but usually it was well behind WRVW. It got a signal upgrade in May 2020, going from 3,000 watts to 15,000 watts. Better signal but still only half the coverage of WRVW.
It seems WRVW has local DJs most of the time. It has its own morning show "Woody & Jim." It doesn't run a national iHeart morning show, like Elvis Duran (Z100 NYC) or Kidd Kraddick (KHKS Dallas). It does carry Ryan Seacrest in middays, which virtually all iHeart Top 40 stations (and a few Hot ACs) do. But it seems the PM Drive and Evening DJs are local, so that is not the reason it's fallen behind WNFN. WRVW calls itself "The River." That's a slogan we mostly see on adult formats. It's not KISS-FM, like most iHeart Top 40 stations.
I always find it interesting when a lower power station beats its high power rival. I'm thinking of how Class A 102.3 WMMJ (2,900 watts) sometimes beats Class B 96.3 WHUR (24,000 watts) in the Urban AC format in Washington. But that might be explained by most African-American listeners living within Washington and its close suburbs, so WMMJ hits most of its potential listeners.
