KRBI-FM

KRBI-FM (105.5 FM, "River 105") is an American radio station licensed to serve the community of St. Peter, Minnesota and broadcasting to the Mankato area and the Minnesota River Valley. It currently airs a classic hits music format.

The station is owned by Alpha Media, LLC, along with KEEZ, KYSM-FM and KMKO-FM.

From 1966 until 2000, KRBI-FM simulcast with its AM sister at 1310 AM. In later years, the FM station aired an adult contemporary format, with a heavy focus on its hometown of St. Peter. After increasing power from 3,000 to 25,000 watts, improving its signal into Mankato and other nearby cities, KRBI-FM flipped to a more regionally focused classic rock format as "River 105" on September 12, 2000. The St. Peter-oriented programming shifted to its AM sister, KRBI 1310 AM.

KRBI-FM switched its moniker to "The Buzzard" in April 2006.

On January 4, 2010, KRBI-FM changed their format to classic hits, branded as "105.5 The River".

On May 1, 2012 KRBI-FM changed their format from classic hits to adult contemporary, still branded as "105.5 The River".

As of 2018 KRBI-FM has flipped back to classic hits, the station slightly rebranded as "River 105".
