Owned by Hubbard Broadcasting, the station serves the Washington metropolitan area, extending its reach through repeater station WWWT-FM 107.7 in Manassas, Virginia, as well as the second HD Radio channel of WTLP (103.9 FM) in Braddock Heights, Maryland. The WTOP-FM studios, referred to on-air as the "WTOP Glass-Enclosed Nerve Center", are located on Wisconsin Avenue in the Washington D.C. suburb of Chevy Chase, Maryland, while the station transmitter is located on the American University campus.
