Although I was very late getting on 10m WSPR today the first spot was by FR1GZ (9724km). As yet, nothing on 6m again. Our younger grandson only left mid-afternoon.
UPDATE 1555z: The first USA 10m spot today was W4DEX (6390km).
UPDATE 1630z: W4DEX (North Carolina) is the only 10m USA spot today at present. I guess there could be more later, but I doubt it.
UPDATE 1708z: Several spots on 10m from K9AN (6505km). The USA spots are still coming in. Overall, conditions did not seem quite as good as in recent days on 10m with fewer different USA stations spotting me.
