Stefan and Martin, this is an impressive result!
Just for curiosity, have you been
using WSPR-X software to generate the signal, or still the SndOutpt
tool?

PS Stefan I have currently notched your signal
on my grabber to preserve the effectivity of the noise blanker. I hope
you don't mind!

LF,
I'm most excited to see that my last nights
WSPR-15 transmission starting 5:30 UTC was decoded by YV7MAE in
Venezuela:

That's a first
digimode one-way between these continents on LF. The SNR wasn't even close to
the decode limit. Actually the is room for another 6 dB :-) The losses here on
the TX side were even quite high due to the bad WX.
Thanks to
Martin/YV7MAE for running the RX system (http://dl.dropbox.com/u/74746618/LF/YV7MAE_LF_Grabber.html
) all the time and thanks to Joe/K1JT for develpoing this great
software.
