For the first time in many months I have returned to 472kHz WSPR using 10mW ERP from the earth-electrode "antenna" in the ground using my transverter driven with the FT817ND. G1GKN (99km) is a good signal. So far, I have only been copied by G0VQH (15km).
UPDATE 2015z: Best DX on 472kHz WSPR RX is DL7NN (873km).
UPDATE 2120z: The following unique stations have been spotted:
UPDATE 2138z: Although I am not that hopeful, I shall stop on 472kHz WSPR overnight. It is still summer and the noise levels will be high, preventing many stations from copying my QRPP signal.
