WTOP-FM (103.5 FM) – branded "WTOP Radio" and "WTOP News" – is a commercial all-news radio station licensed to serve Washington, D.C. Owned by Hubbard Broadcasting, the station serves the Washington metropolitan area, extending its reach through one repeater station: WWWT-FM 107.7 in Manassas, Virginia. 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. Besides a standard analog transmission, WTOP-FM broadcasts over three HD Radio channels, and is available online.
