[2] The transmitter is situated off Rising Main Avenue at Lanark Street, on a tower that is shared with WPXI-TV and other FM stations in the Pittsburgh radio market.

The standard height above average terrain (HAAT) for Class B FM signals found in Pennsylvania is 152 meters (500 ft) for a station broadcasting at 50,000 watts.

[4] On August 13, 1940, Walker & Downing Radio Corporation applied to the Federal Communications Commission (FCC) for a construction permit to build a new FM station.

[6] The commission granted WWSW, Inc. the authority to cease operations effective December 12, 1945, so the station could be converted to a new frequency on the new band.

[5] On July 25, 1946, the FCC reallocated the station to 94.5 MHz, and granted WWSW, Inc. a construction permit for operation on the new frequency effective November 13, 1947.

By the 2010s, the only 1960s tracks that remain on the station's playlist were those that had a high level of popularity over the years, including songs by The Beatles, Simon and Garfunkel, The Supremes, and The Rolling Stones.

In addition, the station began to incorporate some tracks from the early 1990s into the playlist, including hits from Bryan Adams, R.E.M., Prince and Sheryl Crow.

During the holidays, WWSW suspends some features such as the "All Request Cafe," "The Ultimate Radio Party" and replays of 1970s/1980s versions of American Top 40.

[9] Currently, WWSW has only four live and local weekday airstaffers - Jonny Hartwell (5-10 a.m.), Tall Cathy (10 a.m.-2 p.m.), and Mike Frazer (2-8 p.m.).

Outside of local programming, the station carries talent from iHeartMedia's Premium Choice network (which is also utilized when Cathy and Frazer are absent), which is voice-tracked from out-of-market, as well as several nationally syndicated shows.

On April 25, 2006, WWSW-FM's HD2 subchannel began carrying a format focusing on Rhythmic Oldies, which was originally heard on the former WJJJ (104.7 FM).

In addition, the subchannel carried Duquesne Dukes football and men's basketball games, as well as pre-game, post-game, and coaches shows for both sports.
