Initially, KLOC maintained a general-entertainment format and was one of the stations that carried programming from the United Network during its one month of operation in May 1967. About a year after its sign-on, the syndicators providing KLOC's programming raised their prices to the levels closer to a Sacramento-licensed station (the station's owners had been acquired programming at lower rates closer to that of an unrated television market); KLOC-TV alleged that Stockton's KOVR had pressured syndicators not to do business with the Modesto station. Smith resorted to simulcasting KLOC radio's programming during the daytime hours, including a camera in the radio station's studios showing the disc jockeys live, and ran Spanish-language telenovelas in the evening, when the radio station signed off. In 1972, the station joined the Spanish International Network, predecessor to Univision; soon after came an affiliation with the Christian Broadcasting Network to air religious programs.
