I've been testing the Windows version of the Amalgamated DGPS application on a W10 system. Very nice program ! There are however a few thing that al least makes me puzzled.
- First of all I'm wondering what the difference is between the blue and the black decodes.

Black means the station is being presently received, blue means it has not been received in a few seconds. It's a handy way to see which stations are still being heard right now.
--- Quote ---- The User defined stations list that comes with the program has a wrong file name : DGPSSTATIONLISTING.TXT while it should be dgps_station_list.txt as per the instructions in the Readme file
--- End quote ---
I think I did that so the software would not default to using the external file, but instead the built in list.
--- Quote ---- The row sequence in the stations list that comes with the program is not correct and doesn't fit with the instructions in the readme file.
--- End quote ---
I am not sure I understand what you mean?
--- Quote ---- It would be better to make the "Max zCount error" 6 as advised in the Readme file. Too many newcomers that don't like RTFM'ing drop interest while they think it doesn't work as it should.
--- End quote ---
Yes, that is a good idea.
--- Quote ---- The readme file says "Amalgamated DGPS can decode the entire 285 to 325 kHz DGPS beacon band ". But according to https://www.ndblist.info/datamodes/worldDGPSdatabase.pdf the band starts at 283.5. Are those stations skipped ?
--- End quote ---
Yes, I would have to see if the software can be extended to starting at say 283 kHz. Thanks for pointing this out.
--- Quote ---For the rest, I'm really astonished what this little piece of software is doing. I'm using it together with Perseus IQ files. It saves such a lot of time of decoding frequency by frequency. Really great work !
Greetings from Belgium.

Thanks for the clarifications Chris.

In DGPSSTATIONSLISTING.TXT the row sequnece is
Freq;Baud;Station ID;Ref1;Ref2;Location;Country;Lat;Long
But according to the Readme file it should be
Station ID;Ref1;Ref2;Freq;Baud;Lat;Long;Location;Country
The latter one is working as it should.

Guido.
GuidoS:
In fact this piece of software is really outstanding! I'm wondering if something similar can be build to extract RDS signals from Broadcast FM IQ/WAV Files ?

Yes, it certainly could be done from an IQ file. Not an audio WAVE file as the RDS signal is not present.

Thanks for the prompt reply. The future looks bright.
