OK, so I have now left 6m and QSYed down to MF instead. I am still on 10m WSPR at the same time.
It is still summer time and I think people will struggle to copy my very weak (5mW ERP) signal, especially in daylight. Anyway, I am still using the earth-electrode antenna for now. At least I have a better chance on 472kHz. As mentioned before, with some help, I hope to erect a better antenna that will raise my ERP on 472kHz. This may not happen before late autumn.
UPDATE 1510z: I see that G6AVK (78km) is spotting me on 472kHz WSPR. This is daylight. So far, I have not copied anyone, but at least I am getting out OK on MF. I am not sure why I like MF so much, but I guess it is because I am using my homemade transverter and a fairly unique "antenna". Let no-one tell you you cannot radiate a useful signal on 472kHz. If I can get out with my low ERP (I have been copied over 1000km away on this set-up) and just a couple of earth-electrodes about 12m (at most) apart in the garden, I am sure you can do at least as good or better.
UPDATE 1535z: No further Es on 10m WSPR since the Italian earlier today.
UPDATE 1645z: G6AVK (78km) is now getting me at 5dB S/N better than earlier, not sure why. Still no reports of others or reports from anyone else yet. Things may change as night falls.
UPDATE 1655z: WSPRnet show 17 stations worldwide on 472kHz WSPR. I need a few more "in range" stations active this evening, such as G8HUH (250km) who copied me last time I was active in the summer.
UPDATE 1840z: Plenty of spots by G6AVK but no-one else spotted or spotting me so far on 472kHz WSPR.
UPDATE 1910z: G6AVK spotted (eventually) in the last few minutes. Also G8LCO (58km) spotted me.
UPDATE 2102z: PA0A (417km) and G8HUH (250km) are the best DX on 472kHz WSPR today, well so far.
