and was formally deleted on January 2, 1923. Early reviews in the Sacramento Bee treated KVQ as a separate station from the later KFBK, and government regulators at the time consistently considered the two to be separate, unrelated stations. Early history KFBK was first licensed, as the city's second broadcasting station, on August 16, 1922, to the Kimball-Upson Company, and initially was operated in conjunction with the Bee's primary competitor, the Sacramento Union. The call letters were sequentially assigned from an alphabetic list maintained by the Department of Commerce, which regulated radio in the United States at this time. KFBK began test transmissions in early September, and made its formal debut broadcast on September 17, 1922. Initially there was only a single wavelength, 360 meters (833 kHz), available for radio station "entertainment" broadcasts, which required stations in various regions to develop timesharing agreements assigning operating hours. As of November 1, 1922, there were seven "Inland Stations" sharing time on 360 meters, with KFBK allocated 6:00 to 6:30 P.M. daily except Sunday, plus 8:00 to 9:00 P.M. Thursdays and 8:00 to 10:00 P.M. Sundays. In May 1923 the Department of Commerce greatly expanded the number of broadcasting station frequencies, and later that year KFBK was assigned unlimited use of 1060 kHz. A series of reassignments followed, until November 11, 1928, when, under the provisions of Commerce's General Order 40, the station was assigned to a low-powered "Local" frequency, 1310 kHz. As was true with most stations in the early 1920s, KFBK was initially operated without advertising, and was primarily used for publicity purposes. The Sacramento Union eventually ended its close association with the station. In 1925 the Sacramento Bee saw this as an opportunity to re-enter the broadcasting field which it had left nearly three years earlier when it had shut down KVQ, but now on a commercial basis. Effective September 1, 1925, the James McClatchy Company, a local, family-owned company which owned the Sacramento Bee, Modesto Bee and Fresno Bee newspapers, made an agreement with station owner Kimball-Upson for a half interest in KFBK's equipment and good will. The Kimball-Upson company was granted a $3,000 credit for advertisements placed in the Bee, while the newspaper company agreed to enlarge the station's studio and pay for KFBK's operating and maintenance expenses. As part of this arrangement, McClatchy assumed control over all airtime sales at the station, with net profits up to
