The earliest USA spot today was at 1240z by W3CSW (5886km).
It is now almost teatime at 1658z and KB9AMG (6300km) is currently still spotting me. Somehow I doubt this will be the last.
UPDATE 2012z: KE6BID (5295km) was the last USA spot at 1812z. Since then, just local G4IKZ (18km) spotting me. His beam must be better aligned my way tonight as he as been getting around the -19 to -21dB S/N level.
