WPHI-FM (103.9 MHz) is a commercial radio station licensed to Jenkintown, Pennsylvania, and serving the Philadelphia metropolitan area.

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.

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.

[3] On November 9, 1992, at midnight, co-owned WDRE from Garden City, New York, started simulcasting its modern rock programming with WIBF-FM.

", a lucky (or unlucky) listener was selected to "pull the plug" on WDRE, with the station ending with the first song that started the format: Pearl Jam's "Alive".

On February 10, 1997, after a weekend of stunting with classic soul music, the station flipped to urban contemporary, branded as "Philly 103-9".

Except for "The Yolanda Adams Morning Show" and CeCe McGhee weekday afternoons, the station ran without DJs throughout the day until August 2007.

In late August, the addition of performer Lonnie Hunter from Chicago was named the midday personality along with Sheik Meah.

[19] Eight months after WPHI's format switch, WISX flipped to a classic hip hop-leaning rhythmic AC on June 30, 2017.

[20] On November 5, 2020, Urban One announced that it would swap WPHI-FM, WHHL and the intellectual property of WFUN-FM in St. Louis, and WTEM in Washington, D.C. to Entercom, in exchange for WBT/WBT-FM, WFNZ and WLNK in Charlotte, North Carolina.

Under the terms of the deal, Entercom would take over operations of WPHI-FM under a local marketing agreement (LMA) on November 23, and flip it to a simulcast of KYW.

[21] Ahead of the change, the "Hip Hop" format and branding moved to WRNB on November 16, and the two stations simulcast for a week.

The WPHI call letters were retained to prevent competitor re-use (Nielsen's measurement systems no longer require specific callsign verification by panelists).
