Thanks Jay.
Amazing, isn't it? There is a 34 character message buried in that noise and you can decode it in > 6000 km.

Hi Jay,

Nice, thank you.
I was listening to the song last evening, beside the christmas tree. We actually had some snow yesterday, but just 5 cm and only for half a day.
That's our longest message so far.
It would be interesting to see the phase plot, for getting an impression about the phase stability.
