KISN (Vancouver, Washington)

KISN was an AM radio station licensed to Vancouver, Washington and broadcasting to Portland, Oregon. broadcasting on 910 kHz and licensed for 5,000 watts. The station began broadcasting in 1939 as KVAN, but after it changed formats to Top 40 and became KISN in 1959, KISN became not only the number one rated rock station in the market (the station followed a Top 50 playlist),^[1] but at times the most popular radio station in Portland. In 1976, the FCC revoked KISN's license and others owned by the Star Stations group due to a series of indiscretions involving connections to candidates for the United States Senate in Indiana and Oregon.^[2] The KISN call letters have been used several times for oldies radio stations in the Portland area, most recently by KISN-LP, a Low-power broadcasting station that has been on the air since 2014 with a format that recalls the original.
