Thanks once again Paul for your outstanding work. It is great to see what you can make of such a feeble signal, so close to the ultimate SNR limit. Thanks also Lubos and Stefan for continuously running and maintaining your sensitive and useful grabbers.
Unfortunately VLF transmissions from here depend on a number of circumstances, and they are not easy to predict and announce beforehand. When I don't have to go to work, and if the wind stays calm, and the weather is dry, and the static background is low, and none of my neighbors complains about the beeps, I might try another one tonight or tomorrow ;-) 
Best 73,
Markus (DF6NM)

Decoded 'DF6NM' at Eb/N0 = +0.3 dB, BER 36.5% which
is 67% of capacity.

Carrier 10:25 to 11:25 UT had flux density 0.05 fT
and S/N 11.4 dB using H-field alone. I combined
with E-field to get a couple more dB for the decode.
