All...
I am new to this forum... this topic might not be relevant, but here goes...
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.

=============
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.
