Re: [44net] Internet linked RDF networks

Does anyone here have any interest in remote reporting radio direction finders ? ( RDFs ) I have developed technology for that, using Doppler direction finders.. suitable mostly for VHF and above. ============== Explaining it takes some time, but I have posted a YouTube video of a single DF station, running in TEST mode, located at my residence in California. ( video is about 1 minute long ) https://www.youtube.com/watch?v=GdJqKNpWG5c The DF displays on any PC's GoogleEarth screen, if a suitable PLACEMARK is installed for it. ( not sure about smart phone versions... ) It "refreshes" once every 3 seconds, and ( in TEST mode ) the DF bearing line ( 25 miles long ) rotates clockwise at 1 RPM. ============== This is a YouTube recording, but the real DF station ( still running in TEST mode ) can be viewed "in realtime" if I provide a KML link for it. Contact me if you want to see that... I will provide more info "off forum" about how to install and use the link in GoogleEarth. Bob Simmons / WB6EYV / pelican2(a)silcom.com ============= Multiple DF stations can be plotted simultaneously, on multiple displays... yielding a plot showing the approximate location of the "hunted" station... literally, "in seconds". If multiple hunters ( at many different locations ) are watching the same plot, those "far away" can ignore it... but those "nearby" can jump on it and maybe find the hunted station. That's the general idea... a jammer can't even "cough" without revealing their ( general ) location. ============= I'll provide more details for those who enquire, I prefer a phone call, ( include your number, if you please ) because e-mails are slow to compose. This is still in an "experimental" phase, but the basic technology is all mature and solid... All the pieces have been individually tested, time for a complete network to be built.... and I can't do that alone.
