Hello All,



I have written software for a VHF DSP Doppler Direction Finder


The project is called a SuperSimpleSoundDoppler.

You can build it for about 20$

You need:

A PC with a stereo input Soundcard
A VHF FM porto, scanner or mobile set
A GPS Mouse with NMEA0183 output
The homebuild SuperSimpleDopplerPeiler


The SuperSimpleSoundDoppler consists off:
-----------------------------------------

4x vertical whips(abt 50 cm ) mounted on a round board
of about 60 cm diameter with a switcher unit.


A electronics board with 3 transistors
and 2 cheap ic's 4013 and 4001 and
a 5 volt voltage regulator.


The software shows a pelorus and has it's
own MyMapping software witch works with UI-View32 Maps
But it also can plot on Google-Earth through a kml file.

You can also use Mymapping with a doppler
that gives a mixed GPS and Agrelo format.


Existing Dopplerfinders can be very easy interfaced by just a lowpass filter
of some R, c's and a transistor connected to one of the antenna switch signals.


You can find the free software on our Radio Club site.

The software is updated regualairy.

In the software are all the circuit diagrams.

Looks interesting.  Too bad it's relegated to Windows only.  Sad

Hello All,

Yes I know it is for Windows only but
I intend to write it also for the
IPad and Android if i have time to to that.

and have the equipment for it.

Anyone who wants to have it running on Linux
is free to write it in C or Perl  I think.

With the same hardware it should be possible to write
it for a program under Linux.

Maybe it's also possible to write it in mono.dot.net

I am very busy to rewrite SoundDoppler in Visual Basic 8.0
Just like MyMapping already is.

I am not a pro software writer I just do this for hobby.
