KUSD was the name of a former AM radio station run by the University of South Dakota in Vermillion, South Dakota, and a current FM radio station run by South Dakota Public Broadcasting. KUSD AM's call letters and its first license for regular programming were granted on May 27, 1922, although the station held earlier licenses dating back several years. One of its original call signs was WEAJ. Student E.O. Lawrence (who later won a Nobel Prize in Physics) and USD Dean Lewis Akeley were largely responsible for putting this historic station on the air. In its early years, KUSD AM was largely run by a single person, with support from students who volunteered their time.
