The station is owned by Audacy, Inc., simulcasting an all-news radio format with co-owned KYW 1060 AM. The radio studios are in Audacy's corporate headquarters in Center City, Philadelphia. WPHI-FM has an effective radiated power (ERP) of 270 watts, as a Class A station. The transmitter tower is in the Roxborough neighborhood of Philadelphia (). The station is short-spaced due to adjacent channel interference from WMGM in Atlantic City, WXCY-FM in Havre de Grace, Maryland, and WNNJ in Newton, New Jersey (all located on 103.7 FM) and WAEB-FM in Allentown and WNNK in Harrisburg (both located on 104.1 FM). History 1960-1992: Early years On , the station signed on the air. Its original call sign was WIBF-FM and it was owned by Fox Broadcasting, not related to the more recent Fox Broadcasting Company television network. The call letters stood for the station's owners, brothers William and Irwin Fox and their father Benjamin Fox, a local real estate developer. In the 1960s and 1970s, the station featured a format of MOR, big bands, Dixieland jazz and the area's first FM country music show, plus religious and ethnic programs. By the mid-1970s, the station switched to Christian radio and ethnic programming during the day and Spanish-language tropical music at night. The Barry Reisman Show, featuring Jewish music and talk, was broadcast during the afternoon drive time from 1969 through the station's sale in 1992. In 1965, the station picked up a television sister in WIBF-TV, channel 29 (now WTXF-TV, a station coincidentally owned by the Fox Broadcasting Company). 1992-1997: Modern rock The station was sold by the Fox family in October 1992 to Jarad Broadcasting. On November 9, 1992, at midnight, co-owned WDRE from Garden City, New York, started simulcasting its modern rock programming with WIBF-FM. WIBF's branding was changed to "103.9 WDRE" to match the New York station. The simulcasting was part of a large effort by Jarad called "The Underground Network", a group of seven stations from across the country simulcasting WDRE. In 1995, the network ceased operations. WDRE in New York changed its call letters back to WLIR. That made WIBF-FM in Philadelphia an independent, local modern rock station. WIBF-FM then changed its own call sign to WDRE - "We DaRE to be Different" - to match its branding. WDRE used
