WBAA and WBAA-FM are the call signs for two American radio stations owned by Purdue University in West Lafayette, Indiana—an AM station at 920 kHz and an FM station at 101.3 MHz. Both broadcast from studios in the Edward C. Elliott Hall of Music on the Purdue campus, and the transmitters are located in Lafayette, Indiana.
AM 920 
WBAA is the longest continuously-operating radio station in Indiana, having been licensed on April 4, 1922. It was one of several AM stations signed on by Midwestern land-grant schools in the early days of radio. A fire in 1929 took WBAA off the air for several months. Due to its transmitter power and Indiana's flat land, its 5,000-watt daytime signal reaches a potential audience of 2.5 million people, including the fringes of the Indianapolis and Terre Haute areas.
AM 920 WBAA airs a mixture of NPR and local news/talk programming during the day. Evenings are set aside for music programming with adult album alternative music program, World Cafe from 7-9pm, and traditional jazz filling up the remainder of the overnight schedule. Weekends consist of similar programming plus ethnic and local music programming on Sunday nights.
FM 101.3 
WBAA-FM began broadcasting in 1993. It is one of the few NPR stations located on a commercial frequency. The station was assigned the call sign "WBAA-FM" by the Federal Communications Commission (FCC) on April 19, 1991.
FM 101.3, WBAA-FM, simulcasts its AM sister station in the morning and late afternoon to broadcast popular NPR talk programs such as Morning Edition, All Things Considered, Weekend Edition, and Marketplace. Classical music can be heard at other times, as well as A Prairie Home Companion Saturday evenings from 6 to 8, Car Talk Saturday mornings at 10, and Hearts of Space Sunday evenings from 9 to 11. WBAA-FM also has a strong local news initiative.
WBAA and WBAA-FM employ Tim Singleton as general manager. The radio station duopoly has a general staff of about 20 news reporters and on-air hosts, including many full-time professionals and multiple Purdue University students.
