KSDJ-FM streams alternative, indie, punk, and rock out of Brookings, South Dakota, run entirely by students at South Dakota State University under the on-air branding "New Rock 90.7."
A Call Sign With a Previous Life
The KSDJ call letters did not start in South Dakota at all. According to Wikipedia, they first belonged to an AM station in San Diego that began broadcasting in 1946 under ownership of the San Diego Daily Journal newspaper. The FCC did not reassign the letters to the current Brookings station until May 14, 1993, meaning today's college rock outlet is running a call sign with nearly five decades of unrelated broadcast history behind it.
Run by the Same Newsroom Since 1885
KSDJ-FM operates under The Collegian, South Dakota State University's independent student news organization that has covered campus since 1885, according to the station's own page. That structure puts the radio station inside a much older student media operation, with a rotating staff of student directors handling music, news, sports, and production, plus recurring features like the Conversations with COJO interview series and a Jackrabbit Sports Hour covering SDSU athletics alongside the alternative and punk rotation.
Why Tune In
KSDJ 90.7 gives Brookings an alternative and punk-leaning rock station built and staffed entirely by students, carrying a call sign that outlived the San Diego newspaper station it once belonged to. For listeners chasing college radio's DIY energy over a polished commercial format, it delivers exactly that.
