With very good Es on both 10m WSPR and 6m JT65, I think it is time to move over to 10m JT65 just in case there is some F layer DX about. I am off to go QRT on 10m WSPR and start up 10m JT65 and do a manual re-sync to internet time "just in case".
UPDATE 1735z: Now QRT on 6m JT65 and 10m WSPR and active (2W) on 10m JT65. There are several South Americans active on 10m JT65 so we'll have to see if there is any propagation.
UPDATE 2006z: Just EU7KBB (1931km) in Belarus spotted on 10m JT65. No South Americans. It is still not too late, but I think South American 10m JT65 spots are unlikely today.
