KPH Software Defined Receivers
Now you can listen to the LF, MF and HF bands using the same antennas the operators at KPH use - from the comfort of your computer no matter where you are in the world.
We have installed several Kiwi Software Defined Receivers (SDRs) covering all frequencies from 0 to 30Mc - and made them publicly available via the Internet.
The LF/MF receiver uses a Marconi T antenna while the HF receiver used a TCI-530. Both are located at the KPH receive site where electrical noise is extremely low.
We are still fine tuning the installation but the project has reached the point that it's ready for you to use. Here are the links.

Who We Are
Let's be honest... We're a bunch of radio squirrels. And very lucky radio squirrels at that. We inhereted the last remaining Morse code coast station in North America. It was off the air but it was an intact time capsule.
We made the restoration of KPH to operational status our life's work. That was back in 1999 - the year the last commercial Morse code message in the U.S. was supposedly sent.
Through the trust and vision of the Point Reyes National Seashore we were given permission to begin our project of restoration, documentation and operation. And we've never looked back.
As True Believers in the importance of our maritime radio heritage we have tried to research and document every aspect of the field. 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.
Dedicated MRHS volunteers are busy with the preservation, restoration and repair of the historic artifacts with 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, techniques 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.
We look forward to visits by fellow True Believers in the importance of the preservation of our radio heritage. Please see the Contact Us section for full detail about visiting us. Or subscribe to our Newsletter using the form above for up to date information.
We invite you to peruse these pages for details of our work and of radio history. And we wish you fair winds and following seas.
