XETV-TDT (channels 6 and 16) is a television station located in Tijuana, Baja California, Mexico, broadcasting programs from Canal 5 and NU9VE. Its terrestrial signal also covers the San Diego, California area across the international border in the United States. The station is owned by Mexican media company Televisa, and its technical operations and transmitter facilities are located at Mount San Antonio in Tijuana. From its initial sign-on in 1953 until 2017, XETV broadcast English-language programming and operated business offices, and later a studio and newsroom, in San Diego. The station's American operations were managed by Bay City Television, a California-based corporation owned by Televisa. It was most recently an affiliate of The CW Television Network. XETV ceased its San Diego operations on May 31, 2017; The CW moved its San Diego affiliation from XETV's main channel to a subchannel of KFMB-TV (channel 8.2) the following day; XETV's cable channel 6 was transitioned to KFMB-DT2 on the same date. History Early years (1952–1953) XETV came into existence because of a technical quirk affecting stations in San Diego and Los Angeles. Even after the Federal Communications Commission's Sixth Report and Order lifted a four-year-long freeze on awarding television construction permits in 1952, signing on a third television station in the San Diego market proved difficult. While San Diego and Los Angeles are not close enough that one city's stations can be seen clearly over the air in the other, the unique geography of Southern California results in tropospheric propagation. This phenomenon makes co-channel interference a significant enough problem that the two cities must share the VHF band. By 1952, San Diego (assigned channels 8 and 10) and Los Angeles (assigned channels 2, 4, 5, 7, 9, 11 and 13) already had all but three channels on the VHF band covered. Channel 3 initially had been deemed unusable as a signal because KEYT-TV in Santa Barbara would travel in a straight line across the Pacific Ocean (it would ultimately be allocated to Tijuana Canal Once outlet XHCPDE-TDT). San Diego's first two television stations, KFMB-TV (channel 8) and KFSD-TV (channel 10, now KGTV), which were respectively affiliated with CBS and NBC, were among the last construction permits issued before the FCC's freeze on new television station licenses went into effect. The UHF band, introduced by the FCC after the freeze, was not seen as a viable option; television set makers were not required
