KC1AWS (5308km) spotted me first at 1346z. It is good to see USA spots again although conditions seem "subdued".
UPDATE 1802z: After a slow start on 10m WSPR there been spots from lots of different USA stations.
UPDATE 1825z: All is very quiet on 6m WSPR.
UPDATE 1938z: The last spot by a USA station seems to have been WB2TQE (7097km) at 1722z. No further spots from the USA after this time.
