So far today, my 10m 500mW WSPR beacon has been spotted by 7 different USA stations as well as by one more American who is actually located in Brazil. Despite the "poor" 10m forecast, this seems quite a decent day on 10m WSPR with me. I often find this.
I expect there will be more unique stations spotting me from the USA as the day progresses. It is likely I'll remain on 10m until well after dark here. My 630m WSPR station will be active again this evening and overnight.
UPDATE 1540z: On 6m I spotted G8VDQ (93km) but this was the only spot. No-one has spotted me on 6m today.
UPDATE 1748z: 11 unique stations spotting me from the USA so far today on 10m WSPR.
