WIP-FM (94.1 FM, "Sports Radio 94 WIP") is a commercial FM radio station licensed to serve Philadelphia, Pennsylvania. The station is owned by CBS Radio and broadcasts a sports format. The WIP-FM studios are located on the 9th floor of 400 Market Street in Philadelphia, and the broadcast tower used by the station is located in the Roxborough section of Philadelphia at (40°02′30.1″N 75°14′10.1″W / 40.041694°N 75.236139°W).
Since 1992, WIP-FM has served as the flagship station for the Philadelphia Eagles.
In Philadelphia, FM frequency 94.1 began as WIBG-FM, the sister station of WIBG, and mostly simulcast the AM top-40 station until the mid-1960s, when it began to experiment with a prerecorded "underground rock" format without announcers. In 1968, owner Storer Broadcasting shut the station down while attempting to get permission for an increase in transmission power. WIBG-FM was a restricted class B station at the time, limited in range to avoid interfering with WKOK-FM in Sunbury, Pennsylvania. During 1969, the call letters were officially changed to WPNA when Storer sold WIBG (AM). The station remained silent and the call sign would be changed again before it returned to the air.
Having been unsuccessful in getting the Sunbury station to agree to an FCC waiver, Storer sold WPNA to SJR Communications. (SJR stood for "San Juan Racing", referring to the company's lone US holding: a racing track in San Juan.) SJR changed the call letters to WYSP ("Your Station in Philadelphia"), and quickly made a deal with the Sunbury station that allowed WYSP to increase its power. The station became a full class B, with a non-directional 550 ft. antenna resulting in 39,000 watts effective radiated power (ERP). On August 23, 1971, WYSP went on the air. The format consisted of live announcers playing big-band and easy listening music from half-hour-long reel-to-reel tapes that were produced in-house. The WYSP studios were located in the Suburban Station Building at 16th and JFK Parkway in Philadelphia. A new RCA transmitter and circular polarized five-bay Gates antenna was installed at the transmitter site.
