WTSC-FM (91.1 FM, "The Source") is a non-commercial campus radio station licensed to serve the greater Potsdam, New York area.
The WTSC organization is affiliated with the Clarkson University Student Association (CUSA), from whom it receives the majority of its funding.
WTSC has been on the air since November 1963, at which point it broke away from two other local college stations (WNTC and WCCT).
WTSC provided alternative programming such as live college division I hockey broadcasts.
