It seems that most of the spots of my little 500mW 10m beacon have been from nearer Europeans. This could be "out of season" Es or F-layer backscatter, but today there were far more than usual.
UPDATE 1600z: No USA 10m WSPR spots today, well not so far. I am surprised as usually they would appear well before now.
UPDATE 1614: Well, just to prove me wrong KK1D (5455km) has just spotted me on 10m WSPR. As they say, "one swallow does not make a summer", but at least I am being copied in the USA today on 10m.
UPDATE 1905z: KD0VWO (7412km) copied me at 1700z. Overall, this is has not been a good day for USA WSPR spots on 10m.
