The Federal Communications Commission (FCC) granted a license to the station to start broadcasting at 500 watts of power on 1600 kilohertz.

Power was raised to 1,000 watts in 1949 with the installation of a new 2-tower directional antenna system and the studio was moved to the Hotel Marysville in 1950.

The station was once again relocated in 1963 to an office building on 4th Street in Marysville before moving to its permanent home at the transmitter site in Yuba City in the early 1970s.

Nevada County Broadcasters sold KUBA in August 2010 to Results Radio of Chico Licensee, LLC.

KUBA was one of the first AM radio stations in the country to qualify to add an FM signal under a new Federal Communications Commission ruling.
