Welcome to the new, improved KFS WebSDR HF radio receiver system located six miles south of Half Moon Bay, California USA. This facility is maintained by Craig, W6DRZ, e-mail w6drz@arrl.net. To find out about recent changes to this system, click here. A complete technical description, operating tips, updated propagation information, and a donation opportunity can all be found on the ABOUT page. More information on the worldwide WebSDR project can be found on www.websdr.org.

As an alternate system on the West coast, try the Northern Utah WebSDR, North of Salt Lake City.
For better reception from the East coast, use either NA5B WebSDR in Washington, DC. or Home of K3FEF & W3TKP in Pennsylvania.
