The first station in the USA to copy my 10m 500mW WSPR signal today was WG2Z (5600km) at 1224z.
At present, the latest USA spot is by K9AN (6505km) at 1654z, although I expect to be spotted in the USA again later this evening.
Local G8KNN has been active on 10m WSPR today. Interesting that stations in the USA copy me better than a local 12km away! I think Jon must have a week off work at Christmas.
UPDATE 2010z: The last USA station to spot my 500mW on 10m WSPR was W3CSW at 1824z.
