History
The station signed on the air on April 30, 1962, replacing KEX-FM.[3] Its original call sign was KOAP-FM and it broadcast at 92.3 on the FM dial. The following year, it moved to 91.5 MHz, in the section of the FM band set aside for non-commercial stations. In 1967, the commercial station that today is KGON began broadcasting at 92.3 MHz.
KOAP-FM changed its call letters to KOPB-FM in 1989 to identify with Oregon Public Broadcasting, its parent company.
