WCSB (FM)

WCSB (89.3 FM) is a non-commercial educational radio station licensed to Cleveland, Ohio, United States, featuring a jazz format known as "JazzNEO". Owned by Cleveland State University (CSU) and operated by Ideastream Public Media, WCSB serves much of Greater Cleveland and Northeast Ohio as an affiliate of NPR, Public Radio Exchange and the WFMT Jazz Network. WCSB's studios are located at the Idea Center in Downtown Cleveland, while the transmitter resides atop Rhodes Tower on the CSU campus. In addition to a standard analog transmission, WCSB is available online and simulcast on the second HD Radio subchannel of WCLV (90.3 FM).

From its 1976 establishment until October 2025, WCSB operated with a campus radio and free-form format programmed largely by CSU students.

WCSB began broadcasting on May 10, 1976, with programming from Cleveland State University students, faculty, and staff members. In addition, members of the Northeast Ohio community not affiliated with the university hosted programs on WCSB.

In 2020, WCSB received a grant from the College Radio Foundation to defray costs of replacing the station's antenna on Rhodes Tower.

As a student-programmed station at Cleveland State University until 2025, WCSB aired a wide variety of music, including blues, folk, psychedelic rock, noise, indie rock, experimental, ambient, jazz fusion, electronic jazz, free jazz as well as traditional jazz, hardcore punk, punk, outlaw country, reggae, soca, salsa, emo, synthpop, darkwave, new wave, minimal wave, electronica, IDM, K-pop, heavy metal, death metal and grindcore, hip hop, turntablism and soul. The station also aired late night talk radio, as well as news, information and music oriented toward many of the ethnic groups represented in Greater Cleveland: Latin, Hispanic, German, Hungarian, Polish, East Asian, Arabic, Congolese, and Slovenian. Programming, information and music with a focus on Northeast Ohio was heavily featured. Weekly public affairs programs focused on a range of topics, from drug prohibition to space exploration.

At Cleveland State University, WCSB held annual parties and concerts around Halloween. The Halloween Masquerade Ball began in 2009 to show appreciation to the station's listeners and their undying support as a free event offered to the local community. Until 2016, this event was held at the Cleveland Public Theater in the Gordon Square district of Cleveland.

Other events included Radiothon, an annual week-long fundraising event in November, and an annual record fair in the summer.

On October 3, 2025, Ideastream Public Media took over WCSB's operations via an eight-year public service operating agreement: Ideastream's "JazzNEO" jazz format supplanted WCSB's campus programming, and Ideastream offered internships and career opportunities for CSU students. The transfer was announced by CSU president Laura J. Bloomberg to WCSB management and staff via a Zoom call at 11 a.m. Negotiations between the two parties had been in place for several months but bound to a non-disclosure agreement due to the involvement of a Federal Communications Commission (FCC) license and was without input from students or community members. Staff retrospectively told local media of being nervous when scholarships promised to WCSB staff for the academic year did not materialize and keycard locks to the studios failed to work.
