KZY
KZY was a radio station located in Oakland, California, that was licensed to the Atlantic-Pacific Radio Supplies Company from December 9, 1921, until its deletion on January 24, 1923. It, and the Preston D. Allen station, KZM, were the first broadcasting stations licensed to Oakland.
KZY was the successor to Experimental station 6XC, which dated to mid-1920, and which founder Lee de Forest suggested deserved credit as the "first radio-telephone station devoted solely" to broadcasting to the public. Including its predecessor, KZY's broadcasting history predated that of many better-known pioneer stations, including WWJ in Detroit, Michigan (started August 1920, originally as 8MK), and KDKA in Pittsburgh, Pennsylvania (debuted November 2, 1920 as 8ZZ).
Radio station 6XC was established by radio inventor Lee de Forest following his March 1920 move from New York City to San Francisco. In late 1919, de Forest had restarted an experimental radio station, 2XG (also known as "The Highbridge station"), at his laboratory in New York City, in order to promote the DeForest Radio Telephone and Telegraph company and showcase developments in vacuum-tube technology. Beginning in November 1919, that station had featured a nightly broadcast of news and entertainment. However, in early 1920 de Forest moved 2XG's transmitter from the Bronx to Manhattan without first getting permission from the government, and due to this infraction the local District Radio Inspector ordered him to suspend the station's operations.
De Forest's response was to ship 2XG's 500-watt transmitter from New York to San Francisco, where it was used to start a new station, also operating under an Experimental license, now with the call sign 6XC. Ellery W. Stone made arrangements for the station to be located at the California Theater, thus 6XC was commonly referred to as "The California Theater Station". It began operating in April, and was initially licensed to Lee de Forest, Inc.
The new station's broadcasts would be even more varied than what had been offered in New York, and de Forest personally oversaw the station's construction. The transmitter was located in the flies of the theater, with an antenna strung from the theater roof to the adjoining Humboldt Bank Building. Acoustics were a challenge, because the orchestra needed to be heard by both the auditorium audience and radio listeners. Because of this restriction, the normal radio studio practice of deadening echoes by the use of wall coverings was unavailable. The solution for radio pickup was to suspend a large horn 40 feet (12 meters) above the orchestra, with the horn located above the quieter string instruments and away from the louder drums and basses.
Daily matinee concerts given at the theater by Herman Heller's orchestra were the main source of programming. The station also featured professional singers, including Mary White and Frieda Hempel, plus lectures by prominent speakers including Ellery Stone and American Radio Relay League president Hiram Percy Maxim. Another special program had Robert Newton Lynch, Vice President and General Manager of the San Francisco Chamber of Commerce, sending greetings to the Japanese Armament Conference delegation as it approached the city aboard the Korea Maru. An estimated 1,500 concerts were broadcast by the end of 1921.
In mid-1921 control of 6XC was transferred to the Atlantic-Pacific Radio Supplies Company, which was the local DeForest company representative. In September, the station's primary schedule consisted of daily (except Sunday) concerts from 4:00-4:30 p.m., 7:15-7:45 p.m. and 9:00-9:45 p.m., plus Sunday at 10:00-12:00 noon, in addition to daily (except Sunday) "press" from 7:45-8:00 p.m. The station transmitted on a longwave wavelength of 1,250 meters (240 kHz).
Although initially there were no formal standards for U.S. radio stations that provided entertainment broadcasts, effective December 1, 1921 the Department of Commerce adopted a regulation requiring that stations engaged in broadcasting to the public now needed to hold a Limited Commercial license. Therefore, a new license, with the randomly assigned call sign of KZY, was issued for the station on December 8, 1921. At the same time, it was decided to transfer the station to the home of Henry M. Shaw, the Atlantic-Pacific Radio Supplies president, located in the Rock Ridge section of Oakland, California, and operate KZY from there.
