KMYR moved to its current frequency, 95.7 MHz, in 1970, and also increased its power to current level, 100,000 watts. In 1975, it was acquired by Doubleday, a publishing and broadcasting company, which had bought one of Denver's top AM stations, KHOW, in 1968. After the closing of the sale, KMYR's call sign was switched to KHOW-FM. The two stations simulcasted some of their news and music, but Federal Communications Commission rules at the time required AM and FM stations to broadcast separate programming for most of the day.
