As 10m JT65 got me no spots at all today, I QSYed to 630m (472kHz) WSPR RX this evening. So far on RX the best DX is DH5RAE (995km). ON7ZO (355km) is a new station for me, I think, on 472kHz RX.
To ensure a low noise floor, the PC is running on its batteries and the battery charger is not being used. With the SMPSU charging the batteries the noise on RX runs at S8. Just on batteries, the 472kHz noise floor is S0.
UPDATE 2138z: LA2XPA (1310km) is now the best DX on 472kHz RX.
UPDATE 2236z: EA5DOM (1525km) is now the furthermost DX on this band this evening.
