The station has been assigned these call letters by the Federal Communications Commission since May 14, 2008.
Under a previous owner, the station simulcasted with KYSC in Fairbanks for several years.
KSEW's license expired in 2014 after the application for renewal of the station's license was not filed on time. In addition it had not paid FCC fees for a number of years and efforts to collect the debt were unsuccessful. The call letters appear in the FCC database as D(deleted)KSEW.
