UPDATE 1405z: EB8RO (2888km) has exchanged spots with me. I assume this is F2.
UPDATE 1530z: LU6DAX (11594km) in Argentina spotted on 10m JT65. This band is definitely waking up.
UPDATE 1906z: Now going QRT on 10m JT65 and QSYing to 6m MSK144 RX.
This new digital mode is available in a beta release of WSJT-X. Although keen to give this new mode a try, I think I'll wait until it is...
