Hi Goetz,
I experienced the same... heard some NA stations, mostly on 40m, but they
couldn't hear me. My guess is reason 1) is the best explanation. the noise
after the flare was just too much. And I got the impression that the day side
of earth was stronger affected than we on the night side.
For reason 2) - I think everybody plays by the rules - 100W output. And
antenna gain works both ways.
Reason 3) - well, for a NA station, any contact is valid, except that it does
not bring multis (states). So why should they ignore DX contacts?
Further - there is something like one-way propagation. I experienced it myself
at one time in my life, even with lot's of power and big antennas, nobody
could hear us (that was from Greenland). Noise at the receiving side was
probably one reason, auroral effects another.
Anyway, I will pursue my idea of enhancing this contest with a parallel "EUQP"
which adds a little more fun for non-NA stations...
