WSWI (820 AM) is a non-commercial educational radio station licensed to Evansville, Indiana, United States, carrying an alternative rock format known as "95.7 The Spin".

On July 20, 1946, the South Central Broadcasting Company filed with the Federal Communications Commission to build a new radio station on 820 kHz, with 250 watts of power to operate during daylight hours only.

[5][6] It did not have a network affiliation and presented news, sports, music, and local service programs such as the "Lost and Found Column of the Air".

By October 1951, not only did it have an application awaiting processing, but a TV studio was under construction at the Auburn Heights complex, and president John Englebrecht claimed that it could be on the air in six weeks if it were granted a station.

[18] To prepare to take over the station, the university had to acquire additional tape recorders, a newswire service, and equipment to connect to the transmitter at the WIKY site.

[21] On November 3, 1981, South Central took over operations of WROZ, and ISUE took over the former WIKY AM with the new call sign WSWI and a format consisting of local news, classical music, and jazz.

[30] Beginning in 1988, USI partnered with WPSR (90.7 FM), owned by the Evansville Vanderburgh School Corporation, to permit evening broadcasts of its athletics events.

To provide more air time for students, two longtime specialty shows featuring classical and big band music ended their runs on the station.

[36] The station then rebranded as The Spin in time for the fall semester after press coverage of the FM launch led to a trademark concern; to remain "The Edge", WSWI would have had to pay an annual fee.
