A few minutes ago I turned off the 10m WSPR (no spots) and 6m JT65 and went instead to just 10m JT65. Today does not look too promising, but we'll see.
UPDATE 1525z: So far just G1JGT (35km) spotted calling CQ on 10m JT65.
UPDATE 1700z: PU3AMB (10431km) in Brazil was spotted at 1614z this afternoon on 10m JT65. TEP?
UPDATE 1725z: It is now over an hour since the DX from Brazil was copied on 10m JT65. I shall probably go QRT on 10m shortly and maybe try 630m WSPR?
