I have returned to 472kHz WSPR tonight with about 5mW ERP. Several spots already including some new people that I don't recall from previous seasons. I am again using my earth-electrode "antenna" in the ground.
UPDATE 1938z: G3KEV (232km) is the best DX on 630m WSPR RX so far this evening.
UPDATE 2040z: DK7FC (669km) is now the best DX on 630m WSPR RX this evening. Stefan is always a good signal on MF.
