On 472kHz WSPR again

Since about 2010z I have been back on 472kHz WSPR using 5mW ERP from the short baseline earth-electrode "antenna".  These are the results in the first 44 minutes on the band (TX and RX).

472kHz Jan 1st 2015 - results in first 44 minutes

UPDATE 2130z:   Since this chart was created I have spotted G8HUH (250km) and PA0A (417km).

UPDATE 2212z:    Best DX (on RX) so far this evening is F1AFJ (607km). I shall leave the 472kHz system running overnight.
