Sunrise in Hamilton, Ohio this morning was 1202 UTC.

I don't agree with the comment in your other post that the F-layer will 
support 7 MHz refraction at almost any flux level; it quite clearly 
doesn't at high latitudes at night.  It's quite noticable how the Ws dip 
after midnight here, especially as the winter creeps on, with only the 
big guns and maybe W4s coming through, and the Caribbean and SA stations 
dominating the band.  It's not a bad time for DXing, but a bad times to 
try and run Dubyas in a contest.  Did you mean to say the *daytime* F-layer?

Other than that, great post!
