Thanks a lot Stefan for this nice confirmation! I'm quite amazed that it did work so well. And congratulations to you - as they say, with QRP all the hard work is being done on the receiving side! And I recall our conversation not long ago, when the two of us half-jokingly calculated that we could probably work each other at one bit a day ;-)
The amazing thing is that virtually everybody can do this. For transmitting, all you need is an average LF backyard marconi, or a strapped 80 m dipole with reasonable insulation. We actually live on a fairly small plot, and I have 42 m of wire up at about 7m effective height. A power of 80 W gives around 0.28 A (ie. 21 kV antenna voltage). Thanks to Spectrum Lab, accurate GPS or MSK stabilisation has become almost straightforward.
I have stopped the transmitter now at 18:00, as I do not dare to let it run through the night. If conditions allow, I will try to add another dash tomorrow ;-)
Best regards,
Markus (DF6NM)
