Roger, you raise an interesting point about "you can see (lack of sunrise enhancement) very clearly when there's a contest on".
That is an interesting observation. Several times in the past years I've been on during a weeknight (non-weekend) in winter and observed really great enhancements around sunrise in Europe. I've posted my RBN reports here when I've observed it - it is not at all common for me to be reported at 40dB or 50dB above the noise into Europe on 160M! But when I've been on for a 160M contest weekend I rarely observe it. I wonder if it's just a stream of bad luck that these enhancements have been occurring but only outside contest weekends! Maybe the guys who are super-regular on every morning for a whole year have a better/wider perception than me, who is only occasionally on during the week for EU sunrise. The real experts would be the guys who run and monitor the automated WSPR beacons. I don't know how far back that baseline goes (just a few months ago I didn't even know how to spell WSPR!).
