Since 3s/dot slow CW has not been good enough for this so far, I
suggest we do something like this: As many European stations as
possible transmit very long dashes (90seconds for example), within
a very narrow frequency range (perhaps 20Hz maximum - 10Hz
would be better),

Just a remark. If you want to dig deep into the noise, you must use
resolutions of 5 or 10 milli Hertz. At these resolutions the span covered
by a spectrogram is at maximum a couple of Hertz, so the 10 or 20 Hz
spread would mean that the biggest part of the stations will be outside
the screen.
