About KTSU

KTSU’s mission as a major component of outreach for Texas Southern University is to provide the Houston community with programming that features the richness and depth of our cultural heritage through the presentation of Jazz and other formats, such as R&B Oldies, Blues, Gospel, Reggae and Hip-Hop.  KTSU also provides its listeners with well balanced coverage of current news events that educates and entertains and produces local programs that meet the needs of public service for a well informed community.  In addition, the station provides programs from Public Radio International (PRI) and National Public Radio (NPR) and serves as a training ground for students enrolled in Texas Southern University School of Communication.
