CBS used shortwave to support its Latin American international network, which consisted of 64 stations located in 18 countries and GE's KGEI opened in San Francisco in 1939, transmitting to Asia. [16] [17] [18] On November 1, 1942, all 14 private U.S. shortwave stations ended commercial operations and were leased to the Voice of America. [19]
Skaggs Island Naval Communication Station is a former United States Navy installation located near California State Route 37 between Novato and Vallejo, California.It was a secretive, secure, and self-contained naval base, engaged in a number of communications and intelligence gathering functions for the Navy and other federal intelligence organizations.
The extension also had inductors at the far end, such that each part of the antenna had inductors at its ends. In 1925, the two parts of the antenna were split, each now operating separately (the original as callsign MUU, the 1924 antenna as GLC), a new feed taken up the mountain from the western transmitter buildings to the site of the double ATI.
Utilizing short-wave radio signals, the station would transmit point-to-point to regional transmitters such as in San Francisco, California or directly to ships at sea. [5] On site was also a large concrete building 60 feet (18 m) by 80 feet (24 m) and 20 feet (6.1 m) tall. [5] In addition to this, on July 9, 1923, KEK began operation.

For long-range communications with aircraft, Coast Guard stations use shortwave single-sideband communications. Weather and safety of navigation forecasts involve facsimile as well as other modes over shortwave and mediumwave transmissions. According to the NTIA, the Coast Guard is the seventh-biggest user of radio spectrum in the United States.
The area includes the North Coast, San Francisco Bay Area, Central Coast, and South Coast. The coastline is slowly eroding due to natural processes accelerated by climate change, though much more slowly in other places in the United States. In the last 100 years, the water line has risen less than 6 in (150 mm) along the coast of California.
