As late as 1924z KD6RF (7526km) was being spotted from EM22lr square near Dallas, Texas. There were other USA stations being spotted here earlier too. In addition, CX2ABP (11127km) was spotting me at 1850z (and several times earlier) and there is extensive Es about (this could be F layer backscatter I suppose). Conditions on 10m WSPR remain good.
UPDATE 1955z: KC1AWS (5308km) was spotting me at 1940z.
UPDATE 2025z: CX2ABP (11127km) in Uruguay still spotting my 2W at 1958z.
UPDATE 2240z: Just locals for the last 2.7 hours. The real DX has now ended for the day. I shall leave 10m WSPR running overnight to see what turns up. The clock has just been resynchronized to internet time.
