472kHz WSPR TX (10mW ERP)

After another successful day on 28MHz (10m) FT8 RX with Mauritania and South Africa logged, I have decided to QSY to 472kHz WSPR TX (10mW ERP from the earth-electrode "antenna" in the ground). My first 2 minute transmission was copied by 3 stations with best DX being G8TTI (186km).
