 In November 1987, WCAU-FM dropped the top 40 format in favor of oldies as WOGL, leaving WEGX as the only top 40 station in the market.With the CHR format all to itself, WEGX's ratings climbed even higher, and by the spring of 1988, the station had moved into the top five in Philadelphia Arbitron ratings (1).Former "Partridge Family" cast member Danny Bonaduce made his debut as a radio disc jockey as the station's night man around this time.
