Hi Markus
Not your fault ! I did not use your .USR directly. Tried to reproduce the configuration manually
Then I did not realize about the different time pattern in the files. Now I understand one more detail ;-)
Unfortunately EbNaut reports that the file start is at 18:00:20.760
So it seems it started too late. And the previous file will be one hour earlier, so loosing the end of the transmission
Would it worth to use a bigger FFT of 10 hours for example ?
Anyway show_rawsyms3b produces a very flat graphic. No signs of a signal anywere
I think that means "keep playing" ;-)
