WTBU (A.M. 640 kHz/F.M. 89.3 MHz) is a "
Part 15" student-managed and -operated radio station at
Boston University. This means it is not licensed by the FCC but operates legally under special "low power" rules (not to be confused with
LPFM FCC licensed stations). It has a block-format programming schedule, with individual DJs able to play pretty much whatever they choose during their weekly airshifts (usually two hours in length). Overall the sound skews mostly rock/alternative, but can vary significantly, including pop, urban, rap, classic rock,
Triple-A, trance, electro, industrial and metal...or just true
freeform.
