10m WSPR - 500mW from FT817, some good DX

KZ8C (6290km) was the first to spot my 500mW in the USA today. So far, 8 spots with 500mW from all over Europe, Asia and now the USA again. There were more at 2W this morning before I dropped down to 500mW. Some recent USA reports suggest much lower power would still have resulted in spots from the USA.
10m WSPR - unique spots to 1334z with 500mW
UPDATE 1404z: Who needs high power?  Just been spotted on 10m WSPR by CE4RWS (11974km) when I was using 500mW.

UPDATE 1623z: TI3/AB4AW (8752km) has recently been spotting my 500mW.

UPDATE 1743z:  My 500mW is now being spotted in Canada and in Nuuk in W.Greenland.  500mW seems quite enough on 10m WSPR most of the time.

UPDATE 1810z:  K1PLL (5367km) - nice call - has spotted my 500mW several times and, for now, looks like being the last to spot me today from the USA.

UPDATE 1938z:  The last spot by a USA station was indeed K1PLL at 1758z and my last spots of US stations were of K1PLL and KZ3X at 1804z. Since then, just G4IKZ (18km) spotting me now.

    Interesting. I am running 5W (it's as low as my rig will go) and our two 3 hourly plots on wspr are all but identical. Neither of us has made any headway with the west side of the states.

    The conclusion I draw is that when the band is open, it's open, and when it is shut it is shut: there is no point trying to blast it open with QRO.

    Mark, I know others do better than I do with the same power on 10m, but I tend to agree with you. I think a better 10m antenna would allow me to be spotted with lower ERP. There was an Italian on 10m WSPR this morning with 50W (yes fifty watts) and honestly RA3ABP(Moscow)running a calibrated 100mW to an indoor whip was a decent signal! The Italian was using FAR more power than he needed.

    Hello Mark and Roger,
    I made a analysis of the spots of Mark on 10m for this day. Mark is right, there's no need for QRO. hi. Thanks for WSPR. 73, Bert.

    To Bert -
    I'm running a carefully calibrated 50 mW on 10m. Your analysis matches well with the spots I got today.
