KF4GKY (6406km) was the first USA station to spot my 500mW 10m WSPR beacon today at 1322z. After the dire forecasts this morning I was wondering if 10m would open to the USA at all. So far (it is now 1350z) KF4GKY is the only USA station spotting me.
UPDATE 1815z: W3GXT (5840km) was the last to spot me from the USA today at 1702z. As this was over an hour ago it was probably the last today.
