Near Inverness in Marin County, California — The American West (Pacific Coastal)
AT&T & RCA Receiving Stations
On December 31, 1931, radio-telephone communications was established between the AT&T station and Hawaii. The Atlantic had been bridged by radio-telephone only two years before direct service was established between this station and Sydney, Australia. By 1940, subscribers of the Pacific Telephone Company were linked to over 90 percent of the world's telephones by AT&T's three High Sea's stations: KMI in Point Reyes, WOO in New Jersey and WOM in Florida. Wave propagation technology became obsolete and was replaced by satellite communications. The Point Reyes AT&T station closed on October 13, 1999.

1. AT&T High Seas Service - Wikipedia. Before satellite communication systems were widely available, the only way ships at sea had to communicate with the rest of the world was via radio connections to land stations. To talk to people who did not operate radio equipment, a vessel at sea would make contact with a land station, usually using high frequency AM or single-sideband (SSB) radio. The operator of the land station would patch the radio connection though to a telephone call made over the regular telephone system (referred to as a landline).

2. KPH (radio station) - Wikipedia. The station dates back to the dawn of the radio era in the early years of the twentieth century when it began operations at the Palace Hotel in San Francisco, California, using the callsign "PH". Forced out by the 1906 San Francisco earthquake and fire, the station moved from one temporary site to another until it was acquired by the Radio Corporation of America (RCA) and relocated to Marin County.
