At 1254z, WG2Z (5600km) was the first station in the USA to spot my 500mW 10m WSPR signal today. He has spotted me several times since, as have others from the USA.
So far, 6m WSPR is very quiet here - no spots given or received.
UPDATE 1738z: At 1714z WG2Z was the last USA spot of me today.
UPDATE 1845z: Now QRT on 10m WSPR, but continuing on 6m for a few more hours. Although I can still see G6AVK on 6m (I presume - same approximate frequency) coming through, the signal is too weak and frequency shifting to decode. The drift could be my end as well as at G6AVK'send?
