San Miguel Mountain is a mountain located in Chula Vista, California. It is 2,567' high, and is the 84th highest peak in San Diego County.Because San Miguel is "the highest point close in to the San Diego metro area," it has been home to radio and TV transmitters since the 1960s.

KZSD-LP (channel 20) is a low-power television station in San Diego, California, United States. It is a translator of ABC affiliate KGTV (channel 10) which is owned by the E. W. Scripps Company. KZSD-LP's transmitter is located on San Miguel Mountain southeast of Spring Valley; its parent station maintains studios on Air Way in the Riverview-Webster section of San Diego. As a stand-alone analog station affiliated with Azteca América and later MeTV, KZSD's broadcasting radius only covered northern and eastern parts of the city of San Diego and some adjacent suburbs (such as Poway and El Cajon). Therefore, the station was simulcast in widescreen standard definition over KGTV's second digital subchannel in order to reach the entire market. The unusual numbering for the mapped subchannel in the past as channel 10.15 was in order to align it with KZSD's former cable placement on Cox Communications channel 15 (PBS member station KPBS-TV, which broadcasts on virtual channel 15 over the air, is instead carried on cable channel 11). Once XHDTV-TDT2 (later XHAS-TDT) assumed the Azteca América affiliation, KZSD-LP lost the channel 15 cable slot, but regained carriage on May 1, 2017 on Cox digital channel 808, when it assumed the MeTV affiliation in San Diego. KZSD-LP was converted to digital in 2018 as a KGTV translator, allowing homes with issues receiving KGTV's VHF signal or only a UHF antenna to receive KGTV in some form.

KSWB-TV is branded as Fox 5 San Diego, in reference to its primary cable channel position in the market on most local cable providers (it is also carried in Baja California, Mexico on Izzi channel 92). Until 2011, the logo bug shown during the station's newscasts rotated between its common cable channel position and its over-the-air virtual channel number, 69.

KUSI-TV's studios are located on Viewridge Avenue (near I-15) in the Kearny Mesa section of San Diego, and its transmitter is located southeast of Spring Valley. The station operates translator K03JB-D in Temecula (part of the Los Angeles market). After a 15-year dispute over permit ownership that almost derailed the launch of the station on multiple occasions, KUSI began broadcasting in 1982 as a partnership between United States International University and McKinnon Broadcasting Company. It was the first independent station built in San Diego proper. Financial and accreditation problems at USIU led to the sale of its stake to McKinnon in 1990, with McKinnon exercising veto power to block any sale to another entity. McKinnon then started KUSI's news department, which has since grown to produce newscasts throughout the day. In 2023, McKinnon sold KUSI to Nexstar.
