The station takes its call letters and inspiration from the former KISN in Vancouver, Washington, a then-Top 40 outlet which broadcast from 1959 to the late 1970s.
In 2010, Dave "Records" Stone began an internet stream that served as a revival of KISN, at which he had worked.
The WORC, led by President Ron Polluconi and club member Ken Seymour, were planning to move the club's existing radio station, KQSO-LP, from Newberg to Portland's Mount Scott; KQSO was shuttered because of the launch of an FM translator in Portland.
On August 26, 2014, the WORC installed the transmit antenna for the new station on a tower located in a communications compound on Mt.
Subsequently, a press release was issued on November 28, 2014, where Ron Polluconi announced that "finally after 38 years the KISN call sign and radio signal will return to Portland via the FM airwaves".
