WDCH FM 99.1

A commercial FM station at 99.1 MHz, branded as Bloomberg 99.1, licensed to Bowie, Maryland and serving the Baltimore-Washington metropolitan area. Owned by Audacy, Inc. and operated by Bloomberg L.P., the station functions as the market's network affiliate for Bloomberg Radio, carrying continuous business news and financial programming. Its transmitter is situated in Odenton, Maryland, positioned roughly midway between Baltimore and Washington, which allows the station to deliver a strong city-grade signal to both major markets simultaneously — a technically uncommon arrangement. Studios and offices are located near the Washington Navy Yard along the Anacostia River in Southeast Washington. The station's programming is also simulcast on the HD-2 digital subchannel of 105.7 WJZ-FM. On occasion, WDCH-FM carries Washington Wizards basketball and D.C. United soccer coverage when sports sister station WJFK-FM is committed to a different broadcast. The station traces its origins to WNAV-FM, which signed on in 1949 alongside WNAV 1430 AM from studios in Annapolis, initially providing a background music subscription service to retail establishments before transitioning through several format and ownership changes over subsequent decades.
