It has a free-form radio format, playing adult album alternative music with other genres and specialty programming.
[1] It is licensed under the Federal Communications Commission (FCC) as a non-commercial educational (NCE) radio station.
To sound like a real radio station, it used the call sign WLSU, with the initials standing for the university's name.
The university wanted an FM radio station to be heard not just on campus but around the Baton Rouge area.

KLSU is unusual in that its call sign begins with a K but is located on the east side on the Mississippi River.
