Inscription. The Radio Corporation of America (RCA) wireless stations on the Point Reyes Peninsula were know as the "Wireless Giant of the Pacific." The station locations and cutting-edge wireless technology developed by the company under the leadership of long-time chairman, David Sarnoff, transmitted a signal recognized by shipboard operators throughout the Pacific as station KPH.
Station KET operated point-to-point services at this site beginning in 1931 through receivers affectionately know as "Green Giants." In 1946, ship-to-shore Morse station KPH relocated here and continued commercial operations until 1998.
KPH received one of the first standard three letter call signs in the United States in 1904 when it was located at the Palace Hotel in San Francisco. KPH was acquired by Marconi Wireless Telegraph Company of America in 1912. Two years later Guglielmo Marconi completed a new long-wave receiving station on Tomales Bay, as well as a state-of-the-art transmitting station in Bolinas. The stations successfully made the first wireless transmission across the Pacific that same year, opening up instant communications to Hawaii for the first time, a boon for business and news. The stations were acquired by the newly formed RCA following WWI.

Note the radio antennas in the background.
the station's closure in 1998 due to technological advances in ship-to-shore communications, the National Park Service acquired the Point Reyes and Bolinas radio sites. Members of the Maritime Radio Historical Society (MRHS) stepped forward to partner with Point Reyes National Seashore. Currently operated under the call letters KSM, and licensed for Morse transmission, MRHS members operate the station and a docent program. They work with the park to assure that the equipment, archives, station history and the legacy of its operators are preserved and its storied past shared with the public.

Visit Us... The KPH receive site is open for visitors every Saturday and Sunday from 1200 to 1700 local time. Wisitors are welcome! The receive site is located at 17400 Sir Francis Drake Blvd in the Point Reyes National Seashore, just past G Ranch on the way to the lighthouse.
