By day, KWBY is powered at 10,000 watts, using a non-directional antenna. But to protect other stations on 940 AM from interference, at night it greatly reduces power to 200 watts. Programming is heard around the clock on 250-watt FM translatorK227DU at 93.3 MHz in Salem.
History
The station signed on the air on July 10, 1964; 60 years ago (July 10, 1964).[2] Its original call sign was KWRC. It began as a daytimer station, powered from dawn to dusk at 250 watts but required to go off the air at night. It aired a middle of the road (MOR) format of popular music, news and sports.
In 1988, it changed its call letters to KWBY. It later switched to Regional Mexican music with Spanish-language programming for Oregon's growing Hispanic population.
