It is now 1232z and, as yet, no USA stations have spotted my 500mW WSPR beacon. 4X1RF (3519m) and UR/SWL56 (2283km) have spotted me many times this morning. I think the band will open to the USA and I may be a little early.
UPDATE 1336z: Still no spots from USA stations as yet.
UPDATE 1421z: Still no spots from USA stations as yet. I have my doubts 10m is going to open to the USA at all today.
UPDATE 1445z: First stateside spot of my 500mW WSPR was AB4QS (7087km) at 1426z - very late indeed today. Conditions to the USA seem poor today.
UPDATE 1545z: Today the only USA station to have spotted me on 10m WSPR is AB4QS and he has only spotted me twice. This is definitely a very poor day on 10m compared with recent months. Usually by now I have been spotted by loads of USA stations, despite running just 500mW on WSPR.
UPDATED 1858z: AB4QS was the last station in the USA who spotted me at a very very early 1500z. This makes today one of the worst days on 10m in months.
