Ah, that's very useful. I heard it at S9+10dB last weekend at 0230UTC - this is the strongest heard so far and is as good as the Greek RTTY signal ever gets. What would be really useful is someone who can plot the station's signal strength at night over a long period on a chart recorder (there must be ways of doing this on a computer, too) so it can be correlated with solar data etc.
