Don't QSY yet!

So, I was about to QSY from 10m FT8 to 630m WSPR, but I see very recent South American spots, so left 10m running. In another hour or so, I shall QSY to MF.

UPDATE 1847z: Best DX today on 10m FT8 RX was LU8XAF (13413km). As there has been now DX for over an hour, I think it is time to QSY to 630m.
