Re: DSP SoundDoppler Advice
- Hello EveryBody,
Happy New Year 2013
Okay I wil check the DF opacity in the XML file too first
The two bearing lines are light yellow in my screen and I can see them well if I vanish the map with arrow keys.
Yes with APRSIS I meant ofcource APRSIS32.exe
The way I did implement status messages
like between <<>>
But I see you use !<>! shrieks
But I think thats not a major obstruction.
For the Doppler I want to send message
to set the frequency of the other doppler(s)
That means APRSIS maybe must get in the future
a cat control driver for many trancievers ?
It must be able to set the frequency
and set the mode to fm I think.
But this is future thinking.
If many APRS people are going to hunt with the
SoundDoppler hardware it would be very nice.
And I want in every DF report the frequency if possible.
(That is optional and does not requiere APRS protocoll changes)
But for now I have to find out how to
communicate through TCPIP to APRSIS32.exe
from my SoundDoppler.exe software.
I have not done this before so I must read in MSDM I think.
I have been testing with the control-P text input
It looks all works okay.
from my packet.txt file.
Yes also nice if MyMapping could have input from a TCPIP
I have to find out how to do that.
Tnx's all fer good advice so far.

- Hello EveryBody,
Today I bought/used an inexpensive Euro 28
USB soundcard U-Control UCA202 Behringer.com
Unfortuality it was not sensive enought
It needs about 1 Volt eff for the line inputs
so I build on matrix pcb 2 audio pre amplifliers
with 1 transisto bc547 in each channel.
Now I had gain enough.
These circuit uses about 2 mA at 12 volt.
The fun is that I can have two SoundDoppler.exe running on
one PC with two scanners and two antenna arrays.
And this al displayed on MyMapping.exe
I found out that it is handy to have more colors arrowpoints
so I can see on the map and stationairy from wich doppler the arrow came.
So I have now a red, yellow and magenta arrows.
Red MyOwn, Yellow MyAlias and other Callsigns Magenta.
I did also work today on my New Arduino Uno board to
create a SoundDopplerGenerator with softwitching
and pre and post decay control signals for the
So the packet.tx file or df-report
should have maybe also a setting for the destination field
like APDF01 APDF02
It can ofcource also have a callsign alias with a ssid
Don't now yet how to do that in SoundDoppler.exe.
