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?
 
Best 73,

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:

Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km az
 2013-02-07 05:30   DK7FC   0.137615   -33   0   JN49ik   1   YV7MAE   FK81bd   7812   264 


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.
