This morning my little 500mW 10m WSPR-AXE-CW beacon was copied in Australia by VK6JI (14439km) at 1026z at -26dB S/N. I thoroughly recommend this tiny single PCB WSPR unit that needs no PC. It fits in an Altoids mint tin. This is F2 propagation.
Yet again, I am also trying 6m WSPR with 1W ERP, but so far with no luck again. I am ever hopeful!
UPDATE 1615z: Still an absolute blank on 6m WSPR. Will remain on for a few more hours.
UPDATE 1704z: ND6M (6914km) currently spotting me on 10m. Pretty sure he will not be the last USA station to spot my 500mW.
UPDATE 1854z: W3CSW (5886km) was spotting me at 1844z. Even he may not be the last this evening. Conditions are good still this evening on 10m WSPR.
UPDATE 1912z: W3CSW (5886km) does appear to be the last USA station to copy me from the USA. No more spots since 1844z.
