KPH was a public coast radio station on the West Coast of the United States. For most of the 20th century, it provided ship to shore communications including telegrams (using Morse code) and marine telex service (using radioteletype).
KPH would broadcast regular bulletins of news, weather and other general information to the shipping community, then relay business and personal messages to and from individual ships. Station operators also monitored the international distress frequencies for calls from ships in trouble.
With the decline of Morse code the station was retired, but volunteers have preserved it in operating condition so that it can still be heard on the air on weekends and special occasions, sometimes using the alternative callsign KSM and the amateur radio club callsign K6KPH. KPH is located within the Point Reyes National Seashore in Marin County, California, north of the San Francisco Bay.
