The Maritime Radio Historical Society (MRHS) is a small group of dedicated individuals who share the goals of documenting, preserving and restoring the artifacts of maritime radio history. Our area of specialization is the coast stations, ships and companies of the west coast of the United States. But anything to do with maritime radio anywhere in the world is of interest to us.

Our largest project has been the restoration of ex-RCA coast station KPH which has been returned to operation under the call KSM.  The station is on the air each Saturday using both Morse and RTTY.  For full details please see the Coast Station KSM section.

Other coast stations were bulldozed almost as soon as they went off the air.  By great good fortune the KPH transmit and receive sites are within the Point Reyes National Seashore (PRNS), part of the National Park Service.  Exhibiting vision and trust in equal measure the PRNS staff permitted the MRHS to begin work in 1999.  We have been on the job ever since. 

Dedicated MRHS volunteers are busy with the preservation, restoration and repair of the historic artifacts whith which we have been entrusted.  That work is the foundation on which the real goal of our project rests.  That goal is to assure that the culture, thechniques and traditions of the men and women who came before us are not forgotten.  We feel that the best way to achieve that goal is through actual on the air operations.
