WYFM originally signed on the air as WPIC-FM in 1947, simulcasting sister AM 790 WPIC until the early 1970s. The call letters were changed to WYFM in 1973.
From the early to late 70s, the station was known as "The Alternative at 102.9", playing the music of Jimi Hendrix, Janis Joplin, Cream and lesser-known rock and roll performers. Programmed by Ralph Caldwell with the consultancy of Edward John "Bo" Volz, it was the first station in the area to feature album-length selections and introduce new artists not heard on other stations. The announcers, including Holly, Fid, Vince, Jimmy, Lee, Ralph and others, followed the practice of the day by using only their first name in identifying themselves.
Y-103 broadcast from Sharon/Hermitage, PA until November 1998, when the studios were moved to the "Radio Center" in Youngstown, OH. The transmitter and antenna remained at the Pennsylvania location transmitting from, what was at the time of its construction the tallest self-support tower east of the Mississippi (500'), until 2001. The Sharon tower has since been demolished.
