This station received its original
construction permit for a new FM station in
Redwood Valley, California, from the
Federal Communications Commission on April 25, 2005. The new station was assigned the call letters KAIS by the FCC on May 2, 2005. In December 2007, the station was granted permission to change its community of license to
Hopland, California. In October 2008, the
Educational Media Foundation reached an agreement to transfer this station to One Ministries, Inc., as part of a complicated multi-station deal. The deal was approved by the FCC on November 20, 2008, and the transaction was consummated on December 9, 2008. The new owners applied to the FCC for new call letters and were assigned KORB on November 28, 2008. ==Translators==
