QSYed to 630m (472kHz) WSPR

A few minutes ago I went QRT on 6m and 10m WSPR. I am now active on 630m (472kHz) WSPR with 5mW ERP on TX from the earth-electrode "antenna" On RX (80%) I am not using the preamp. For the avoidance of doubt, I am also using the earth-electrode "antenna" on RX too.

UPDATE 2225z:  In the last 2 weeks my 5mW ERP from the earth-electrode "antenna" has been copied by 23 different stations. This evening it was copied by F1AFJ (607km) in JN06HT. I am sure my earth-electrode "antenna" is not the best antenna for the band by a long way, but it shows large areas of real estate and big antennas and ground systems are not necessary to achieve decent results on WSPR on the 472kHz band.
