There was Es today on 6m and what appears to be tropo in the form of a WSPR spot of ON7KB (299km) quite recently. I shall stick around on 10m and 6m WSPR overnight. I did a hard reset of the 10m beacon about an hour ago so it should be spot-on during the night. The 6m WSPR is directly linked to internet time, so should be fine. I'll go back to 630m (472kHz) WSPR tomorrow evening, unless 6m is magic tonight and shows signs of transatlantic DX, which I somehow doubt.
UPDATE 2112z: All quiet on 6m WSPR now. I shall have to give random MS another go on 6m. I listened (looked) a few seasons back and was surprised what came through using one of the digital modes (forget which one though!).
