WIBF

The 103.9 frequency was one of the last remaining voids in the Philadelphia market. With a leased-time format under Fox Broadcasting, WIBF was an untapped goldmine in the world of formatted radio. Enter Jarad Broadcasting, owners of longtime Modern Rocker WDRE in Garden City, New York. Jarad was quickly developing a cluster of Modern Rock stations with the “Underground Network” moniker. Affiliates included stations in Albany, Memphis, Little Rock, and WIBF. Signing-On with Pearl Jam’s “Alive”, 103.9 would simulcast New York’s WDRE until the demise of the network. Around that time, the WDRE call letters were moved to 103.9, which went live and local until its death in 1997.
