WDSY-FM has an effective radiated power (ERP) of 17,500 watts, its transmitter is located off Shreve Street in Pittsburgh's Spring Hill district.

[3] Originally as a fully simulcast outlet of its AM sister station, it was owned by Golden Triangle Broadcasting and carried a country music format.

[4] In the late 1960s, the Federal Communications Commission ordered FM stations to air separate programming from their AM counterparts most of the day.

[5] WDSY-FM then moved to studios and offices in Foster Plaza in Green Tree, about three miles southwest of downtown Pittsburgh.

The station's ratings flourished under CBS ownership, thanks in large part to a strong lineup of veteran air personalities, including Brian "Monty" Montgomery, Rick "Zeke" Eberhart, Ally Butler, Chris DeCarlo, Stoney Richards, and later the return of Jimmy Roach following a stint at crosstown competitor WOGI.

In response to the launch of iHeartMedia's Big 104.7 (WPGB), the station dropped most gold titles from the 1990s and 2000s in favor of more current material.

On February 2, 2017, CBS Radio announced it would merge with Entercom, bringing WDSY-FM back to its former owners for the first time in nearly 20 years.
