Although I now think it unlikely I'll see any more real DX on 10m tonight, I have decided to stay on the band overnight. There is an outside chance of some more Es and I may get a few UK and near European spots by aircraft reflections. I guess it will be morning before I have any chance of F2 propagation.
UPDATE 1940z: I have just checked synchronisation to internet time.
UPDATE 2022z: No further spots on 10m JT65. I think this is it for the night, although I am still on 10m JT65 overnight.
