Markus,
I be leave, there is problem with the transmission.
Decoding is difficult. The SNR is not as good as with WSPR-2.
I'm using the the same equipment as for WSPR-2, where the reported SNRs are  better.

although the SNR should rather be like + 23 dB! Though I'm not sure wether the WSPR software would be be able to display high positive SNR values at all. You're actually on 475810 as you've said, the 10 Hz offset is from the receive conversion and will be fixed on the next round.
 
Best 73,

Hi Roland, you're strong here at 24 km - solid 60 dB SNR in QRS-3 setting (ie 0.5 Hz noise bandwidth). Unfortunately no decode yet but I'll keep trying. 
 
How are you generating the signal? There seems to be a set of sidelines approximately every Hz or so, and also a slight downwards drift (see screenshot - during the first couple of minutes I was still playing with the gain settings). Also on the MF grabber
 
Best 73 and good luck,
Markus (DF6NM)
