reason, the Nu9ve subchannel cannot use channel 9, due to signal overlap with KCAL-TV over much of the same area. Most Tijuana stations face similar signal overlap issues in this area to Los Angeles stations that preclude them from using the virtual channels that correspond to their networks. Repeaters XETV operates two repeaters, on Cerro La Nopalera in Tecate and Colonia Playas de Tijuana. Both repeaters broadcast on channel 23 in areas where the main channel 23 signal from Mount San Antonio provides insufficient or no over-the-air coverage and are co-located with identical transmitters for XHUAA and XEWT. Radio Prior to the termination of the station's analog broadcasts, XETV's audio signal could be heard at 87.75 MHz on the FM band in San Diego, Tijuana, and surrounding areas, though at a slightly lower volume than other FM radio stations. Unlike the digital ATSC standard, analog NTSC carried its sound on an FM subcarrier, and TV channel 6 (82–88 MHz) is adjacent to the standard broadcast FM band. When XETV-TV shut down its analog signal on May 28, 2013, it shut down the station's 87.75 MHz audio subcarrier. An analog FM broadcast receiver cannot tune and decode digital television on any frequency.
