>>>> CURRENTLY TESTING - EXPECT FREQUENT OUTAGES <<<<
This WebSDR, located at the historical Point Reyes radio station KPH, is operated for the benefit of the amateur radio community - and anyone interested in HF radio communications.
For more information about the KPH historic site see:
The National Park Service web page here for the Point Reyes radio station.
The Maritime Radio History Museumlink - The Marine Radio Historical Society (MRHS) is an organization dedicated to the preservation of this site.
This server's receiver is connected to a TCI-530 Omnidirectional antenna - a 94 foot (29 meter) tall mast with a maze of wires, capable of reception across the entire HF spectrum.
At present this server is being operated experimentally, using a single GPS-referenced RX-888(Mk2) SDR for reception on all bands and is subject to occasional restarts and reconfiguration. As it is still undergoing testing, frequency labels, etc. are not yet fully-implemented.
More information about the WebSDR project in general can be found on http://www.websdr.org. For questions about this WebSDR contact: rob ( at ) robinett . us
