WBCA was a short-lived commercial FM radio station, licensed to Schenectady, New York. The station, originally W47A, launched on July 17, 1941, as the first commercial FM station without an associated AM station. The call sign was changed to WBCA in 1943. Despite initial optimism that FM stations would soon supplant the AM band,[1] WBCA ceased operations in 1952 due essentially to the small number of FM receivers in use.
