KYJ (Los Angeles)

The Meyberg Company was an electronic parts distributor, with offices in Los Angeles and San Francisco, and boasted it had "the largest radio stock of the Pacific coast".

6XAK was the second station established by Meyberg to provide a broadcasting service, as earlier in the year the company began operating 6XG (later KDN) from the Fairmont Hotel in San Francisco.

[4] 6XAK began operating in September 1921, transmitting on a wavelength of 310 meters (968 kHz) from Hamburger's department store (which became the May Company in 1923) at 8th and Broadway in downtown Los Angeles, and the station quickly received national attention.

[5] In conjunction with the opening of the station, Hamburger's introduced free radio classes, which could accommodate forty at a time, and were "aimed to fit students for the Federal exam for license as a first-class amateur wireless operator".

[7] From 1912 to 1927 radio communication in the United States was regulated by the Department of Commerce, and originally there were no formal requirements for stations, most of which operated under Amateur and Experimental licenses, making broadcasts intended for the general public.
