USA yet again on 10m - multi-hop Es?

KZ8C (6290km) was spotted twice this evening from EM88pm around teatime. It seems WSPR is proving the summertime Es path to the USA on 10m is open far more than I previously thought.  I am losing count of how many times this season I have copied the USA on 10m, but it is a lot - on 6 days now I think.  I assume it is multi-hop Es but could be F2 backscatter? More WSPR stations would help. Remember, if this is Es the same may be possible any summer including right at the sunspot minimum in 5-6 summers from now. Now there's a thought.

UPDATE 1835z:  DK0SC (827km) copied me very strongly at +7/+8dB S/N at 1758z. Since then just wispy weak signals which are probably GDX stations not quite strong enough to decode. G8VDQ (93km) was decoded at 1730z.

UPDATE 1950z:  Worldwide just 13 stations on 10m WSPR and only 12 stations on 6m. This is pathetic. People are really missing out on an excellent mode for propagation studies and more. To be fair, the list does not show people on WSPR who have not spotted or been spotted in recent minutes, so there may be more people active than are shown on www.wsprnet.org .

UPDATE 2222z:  Three Es spots this evening of SI9AM (1503km) up in N.Sweden on 10m so far this evening. Will leave 10m WSPR kit running overnight.
More recent WSPR spots today


PS  Get Israel to makr peace, not war.
