QSYed to 472kHz WSPR

After a total dead loss on 6m with 30dBm ERP,  I have now QSYed to MF with 5mW ERP from the short baseline earth-electrode "antenna".

Already PA0O (440km) and G3WCB (101km) have been copied strongly and my weeny 5mW ERP signal has already been spotted by G8LCO (58km) and G3WCB (101km). Even with a much lower ERP, MF is so much more productive than 6m at this time of the year.

UPDATE 2145z:  F1AFJ (607km) is currently the greatest DX on 472kHz WSPR on receive.  I'll leave the kit running through the night to see if I see anyone at even greater range. I may even be seen by the odd DX station on TX. I am still using my short baseline earth-electrode system.

UPDATE 2245z:   PA0A (417km) is a colossal signal right now.

UPDATE 2310z:   Although still active on 630m (472kHz) WSPR and I shall be overnight, I have now gone QRT on 10m as I am only being copied by local G4IKZ (18km) on 10m since teatime. Looking for new reporters on 472kHz WSPR. So far this evening, just 3 unique stations have spotted me on 472kHz. BTW set to 474.2kHz  USB dial for  472kHz WSPR.
472kHz unique spots so far tonight with 5mW ERP from earth-electrodes.

Think you have two transposed digits in the dial Fx Roger, only you don't do that kind of thing as much as I do!!
MF has been a bit quiet in the last week or so, there are not many stations transmitting and some only make guest appearances then go back to R.

Did manage to spot SV3DVO's 5mW from Greece so you can get a long way (2200km) on less radiated power than a panel LED.

By the way, WSPR's old dbase seems to go back a bit more that the current one, it's a clickable link in some screens.

Thanks Alan. Error corrected now!
