Return to 472kHz WSPR RX

After a break, I returned to 472kHz WSPR RX at about 1950z. Quite a few spots already including some stations I have not seen before this season. As before, I am still using the earth-electrode "antenna" in the ground. There would seem to be far more stations on MF WSPR than on LF WSPR.

UPDATE 2020z: So far, 11 unique stations spotted.

UPDATE 2310z:  For a while I have the shack PC on charge, so I can go on 472kHz WSPR RX overnight with a low noise floor. I'll put the shack PC back on battery power for the overnight period.
