The third signal in the market for San Diego via VHF, XETV national stations due to technical problems in involvement in San Diego and Los Angeles. Even before the Federal Communications Commission lifted a freeze on four long years of granting construction permits for television in 1952, the signing of the third season in San Diego promoting difficulty. While in San Diego and Los Angeles are not close enough to a station in the city can be seen clearly through the air in the other, the unique geography of southern California results in the spread of the troposphere. This phenomenon makes co-channel interference as a big enough problem that the two cities must share the VHF band.
In 1952, San Diego (with 8.10) and Los Angeles (assigning channels 2, 4, 5, 7, 9, 11 and 13) where now 3 VHF channels (3, 6 and 12 were not used in the area ). San Diego in the first two seasons, KFMB-TV (Channel 8) and KFSD-TV (Channel 10, KGTV now), was the last building permit another senal FCC before the freeze took effect and one of the last construction permits issued before the FCC freeze came into force. The UHF band is not seen as a viable option because not all managers were required to include UHF tuners until 1964. Complicating things, the Mexican authorities have assigned two VHF channels in neighboring Tijuana – channels 6 and 12. Since these were the last two VHF channels in the left (channel 3 is considered unusable because it was assigned to Santa Barbara and the signal would be receivable in most parts of the San Diego area, as travel in a straight line over the Pacific Ocean), the FCC does not accept any new building permits in San Diego as a courtesy to the Mexican authorities.
Although San Diego is big enough for a third season, it soon became clear that the only way to get third VHF station would use a signed allocations of Tijuana. Azcarraga family, owners of telesystems Mexicano, forerunner of Televisa, quickly snapped up the license for channel 6, and XETV signed in January 1953 as an independent station. Although it is licensed to Tijuana and ownership of the interests of Mexico, for all purposes to have been a station in San Diego from the beginning, the broadcasting entirely in English with the exception of station identification, mandatory game National Anthem Mexicano (the Mexican national anthem) and technical notices. Tijuana does not get its own station until 1960, when Azcarraga signed XEWT-TV channel 12.
In 1956, the FCC granted permission to XETV bring ABC programming. ABC took a part-time KFSD-TV and KFMB-TV at the time, but ABC XETV delay his exclusive San Diego affiliate. However, the FCC does not allow the American networks to transmit their signals to stations outside the United States. As a result, programs were ABC (on film, kinescope, and later, video) from a place north of the border and then physically transported to the Channel 6 transmitter in Tijuana, a practice known in the television industry as “cycling.” While this agreement legally evaded the station can not acquire a direct mains, leaving XETV unable to carry the network programming such as news and some sports coverage.
Transition
In the late 1960s with Texas-based Bass Broadcasting, owner of independent KCST-TV (Channel 39, now KNSD), began a long battle to take the San Diego ABC affiliate XETV. The station claimed that it was inappropriate for an American television network to join a Mexican-licensed station when a viable American station available. The FCC agreed with KCST then, and in 1972 the Commission revoked the permission Channel 6 to carry ABC programming. The text of the decision of the FCC forced ABC to move its programming to KCST, the single market of the station not affiliated with either NBC or CBS in existence at the time. No wonder ABC was not happy with the way it ended in a UHF station, and only kept for five years until KCST pass KGTV in 1977.
XETV once again became an independent station, with a schedule consisting of deals syndicated off-network programs, movies, and children in the sample. Furthermore, due to regulations restricting non-commercial broadcasting Mexican time citation needed (as did the FCC regulations at the time citation needed ) every Sunday, the station, a forerunner of future changes in the U.S.. UU., became, in effect, the first station in North America to keep an infomercial, citation needed , which consisted of one hour of advertising listings of homes for sale.
