The station signed on as WESO-FM, sister station to WESO. In 1979, the station's call letters changed to WQVR, and before long it had become country station "Q100". In February 1999, under the new ownership of Wilks Broadcasting, the station changed format to classic hits, taking on the call letters WWFX. The station became an affiliate of the syndicated The Bob & Tom Show and changed its name to "100.1 The Fox". That December, the station was sold to Citadel Broadcasting for $14.25 million. The first on-air personalities at The Fox (other than Bob & Tom) were: Worcester radio legend "Zip", National voice talent Moneen Daley and Program Director Dave Hilton.
In January 2003, the station ditched Bob & Tom and took on an active rock format while keeping the name "The Fox" but identifying as "Worcester's Rock Station." That would be short lived, as in November 2004 the station changed format back to classic hits, retaining the WWFX call letters but changing its name to "100 FM The Pike" and ditching its airstaff for a jockless approach. This structure would last just over 3 years before, at the start of 2008, "the Pike" hired its first live on-air personality, longtime Providence broadcaster "Cruisin Bruce Palmer" (formerly of http://en.wikipedia.org/wiki/WWBB). Palmer was initially teamed with former Fox staffer Chris Engel to create a music-intensive morning show. Engel would be replaced 6 months later by current WORC-FM morning show host Adam Webster, providing news updates on Palmer's daily show.
