Already my 10m 500mW WSPR has been spotted in Brazil by KD0VWO (7412km). So far, this is the only DX seen on 10m WSPR today. I remain hopeful that I may be spotted in the USA later today on 10m WSPR.
UPDATE 1415z: KD0VWO (in Brazil) has copied me several times on 10m WSPR, but 6m WSPR has drawn a total blank so far today with no spots given and none received on that band. I am ever the optimist and will stick on both 10m WSPR and 6m WSPR until this evening. Around 1900z I shall switch to 472kHz WSPR RX.
