The wideband and DCF plot of that time is still on the
website. Martin shuts down the PC during daytime.

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.
