KPH (radio station)
KPH is 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). The station discontinued commercial operation in 1998, but is operated occasionally as a historic service - its signal can be tuned in throughout a large portion of the western hemisphere.
(Ship to shore telephone calls were not handled by KPH but by other stations such as the nearby AT&T high seas station KMI.)
==Revenue service and preservation==
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.
