[1] WDAS-FM broadcasts using HD Radio, with a simulcast of WTEL (airing Black Information Network programming) on the station's second digital subchannel.

WDAS-FM is considered to be a heritage radio station in Philadelphia, pioneering a format for adults in the African-American community.

Widely regarded as an originator of the Urban Adult Contemporary format, WDAS-FM continues to be among the most popular stations in the Delaware Valley.

This short-lived period introduced much of the new voices of "progressive rock" radio, including Michael Tearson and Ed Sciaky.

During the late 1960s and early 1970s, radio stations were under increased pressure by the Nixon administration through the FCC to censor music that involved drug content.

While playing Arlo Guthrie's "Coming Into Los Angeles", which referenced smuggling marijuana, Leon charged into the station and ripped the turntable arm off the record.

WDAS-FM's rising success paralleled the red-hot popularity of the new R&B sound developed at Philadelphia International Records.

By the end of the decade, WDAS-FM introduced its listenership to new sounds of rap with artists such as Sugarhill Gang, Grandmaster Flash and the Furious Five and Kurtis Blow, as well showcasing local talent like Frankie Smith (of "Double Dutch Bus" fame).

Legendary broadcasters George "Georgie The Man With The Goods" Woods and Edward "Ed" Bradley shaped the political voice of the station.

The station was sold in November 1979 to Black-owned Unity Broadcasting Network, and it honed the Urban Contemporary format in 1980.
