472kHz WSPR

About 30 minutes ago, I QSYed to 472kHz (630m) WSPR using the earth-electrode "antenna" in the ground (10mW ERP). Even though the transverter crystal takes about 20 minutes to fully settle, plenty of spots on RX and TX. At the moment (it is still light here) best DX on RX is PA3ABK (306km).
