Peter,
 
what you could do immediately is enable the data export for your 47 uHz instance:
 
1. You will need to go to "FFT settings" and at the bottom right set "FFT Output" to "Complex (real imaginary)". Unfortunately this will restart the FFT aquisition so you will have to wait a few hours until the next FFT is ready. All the other settings can just stay as they are.
 
2. Create a folder c:\spectrum\data4H in the main SpecLab directory. In the SpecLab file menu, set up the FFT data export as shown in the attached screenshot. The number of exported FFT bins (8192 in the example) should be half of your FFT size. Take care to correctly enter subtle details like file format, double backslash etc.
 
3. This will create a new text file with each new FFT (every 44 minutes). These can later be read opds once youÄve set it up. Or you could send them here for me to run opds on them.
 
Good luck,
 
Markus (DF6NM)

Hello Stefan, Markus, Uwe.
I did not follow all mailings here, but just now OPDS is under my attention.
I have to learn a lot in short time about this mode ans settings.
Is it possible to send me the 8970 .usr files Stefan.
Not at home these day's so I can't RX on very short time.

Uwe, I'm still listening in OPERA 4H 8.0 and I did decode my own test broadcast, but no sign of your signal Uwe.
Perhaps QSY tot 8970 agan in OPDS4H mode ?  Seemt to work :-)

73's and Happy new Year to you all.

Peter - PA1SDB
