At about 1715z I QSYed to 10m JT65 from 6m JT65. I may have left it too late as I have not had any spots on 10m yet. Maybe, there was no European propagation to link to the TEP area? Anyway, I'll leave things running for a few more hours.
UPDATE 1927z: IZ4RE (1138km) spotted me in the last ten minutes.
UPDATE 2200z: I finally went QRT at around 2145z. In all, 5 South Americans were spotted on 10m JT65, all after dark here. Best DX on 10m JT65 RX was Argentina. I was not expecting to spot any South Americans on 10m this late. Surprised again!
