krsu

KRSU is a broadcast call sign that has been used by multiple radio stations in the United States. In the U.S., radio and television stations are assigned call signs by the Federal Communications Commission (FCC). Call signs typically begin with K for stations west of the Mississippi River and with W for those east of it, and the suffixes -FM or -AM are used to distinguish between services when needed. The sequence “RSU” has been assigned to different licensees over time, and the exact station identity associated with KRSU can change through licensing actions, ownership transfers, or branding decisions.

As a call sign, KRSU does not denote a single consistent brand or format. Stations that have used or currently use the KRSU designation may operate under various formats, from music and public radio to news and talk programming, depending on licensing and market needs. The use of KRSU can therefore reflect different institutional owners, including public broadcasters, educational institutions, or private licensees, at different times.

A notable example is KRSU-FM, the FM designation used by a station that has employed the KRSU call sign to identify its broadcasts. The -FM suffix indicates the station operates on the FM band, distinguishing it from any potential AM service that might share the same base call letters. Because call signs can be reassigned or rebranded, the current identity of KRSU-related stations may differ from past usages.
