[14] Sun River also bought KOPR-FM 106.3 and changed its call letters to KOOZ in 1977; that station aired an easy listening format for much of the next 12 years, except for a brief period in late 1984 and 1985 when it was Top 40-formatted KQDI-FM.

[17] Both stations were devastated when the Scan-Am Building downtown, which housed KQDI-AM-FM and other businesses, burned to the ground on July 27, 1989.
