WCSP-FM, also known as C-SPAN Radio, is a radio station owned by the Cable-Satellite Public Affairs Network (C-SPAN) in Washington, D.C. The station is licensed to C-SPAN's corporate owner, the National Cable Satellite Corporation, and broadcasts on 90.1 MHz 24 hours a day.^[3] Its studios are located near Capitol Hill in C-SPAN’s headquarters.^[4] In addition to WCSP-FM, C-SPAN Radio programming is also available online at c-span.org and via satellite radio on SiriusXM channel 455. WCSP-FM broadcasts in the HD (digital) format.^[5]

Prior to C-SPAN's acquisition of the 90.1 frequency in 1997, the station operated as WGTB-FM, the student radio station of Georgetown University, from 1960 to 1979. Increasingly contentious relations between students and university administration led Georgetown to sell the license to the University of the District of Columbia, which operated a jazz-format station as WDCU from 1982 to 1997.
