WILY and WEEP. In 1947, the station signed on the air, using WILY as its call sign. The station primarily served Pittsburgh's African American audience in the 1950s.

Unable to compete with KQV in the Top 40 format, WEEP changed to country music in 1965, in which it enjoyed its greatest success. Most large cities in the North did not have a radio station playing country and western music, so WEEP was alone in the format for many years. Based on WEEP's good ratings, the owners switched WEEP-FM (now WDSY-FM) to country music as well, a first on Pittsburgh's FM dial. Other than a one-year period with a talk radio format in 1976 , WEEP aired a country format for almost three decades. By the 1980s, WEEP and WDSY simulcast part of the day, before WEEP flipped to an oldies format on December 15, 1986. Then in September 1990, it adopted an all-business news and talk format. In February 1992, the call letters were changed to WDSY and the station became a full time simulcast of WDSY-FM's country format. This was short-lived with the AM station going back to the WEEP call letters and affiliating with the Satellite Music Network's "Real Country" format delivered via satellite in September 1992 . It later returned to a full-time simulcast of the FM station in March 1995, again as WDSY. Gospel and Christian radio. In April 1997, WDSY was sold and flipped formats to urban gospel as WPGR. In July 1999, the format moved to 1510. Following two months of simulcasting, 1080 changed to a Christian radio format, using the WWNL call sign. Starting out as a music-based station, WWNL has added more talk and paid programming in recent years, affiliated with the Wilkins Radio Network. History of call letters.
