regulators of radio at this time, adopted a regulation that formally created a broadcasting station category, and stations were now required to hold a Limited Commercial license authorizing operation on wavelengths of 360 meters (833 kHz) for "entertainment" broadcasts or 485 meters (619 kHz) for "market and weather reports". By the end of 1922 over 500 stations were authorized nationwide. On December 8, 1921, the Electric Lighting Supply Company was issued a broadcasting station license with the randomly assigned call letters KGC, the second in the county after KQL, authorizing operation on the 360-meter entertainment wavelength. The station's location was listed as Fred Christian's Harold Way home. The shared 360 meter wavelength required timesharing agreements between an increasing number of stations needing exclusive time periods. On May 4 the Los Angeles Times reported that a total of seven local stations were slated to make broadcasts that day, comprising a schedule that ran from noon to 9:00 p.m., with KGC assigned 2:00-2:30 and 7:30-8:00 p.m. KNX On May 4, 1922, the Electric Lighting Supply Company was issued a broadcasting license for a station with the randomly assigned call letters of KNX, also on 360 meters, and located at the company's Los Angeles store on West Third Street.

The new authorization coincided with preparations for a move to the California Theater, broadcasting live music, with Fred Christian continuing as station manager. On June 12, 1922, the Los Angeles Times reported that "After more than two months of preparation, the new broadcast station at the California Theater had its opening program Saturday evening at 9:15, sending out a wavelength of 510 meters [588 kHz]. The station is said to be one of the best in the land, the call letters of which are KNX." KNX's regular broadcast schedule on 360 meters was 9:00 to 10:00 a.m. A week after it commenced operations from the theater, the Times reported that "Numerous reports have come into The Times radio department commending the quality and audibility of material broadcast from KNX, the California Theater radiophone.
