472kHz WSPR (10mW ERP)

A few minutes ago I QSYed from 10m FT8 RX to 630m WSPR (10mW ERP TX 20%, 80% RX) using the earth-electrode "antenna" in the ground. It usually take about 20 minutes for the transverter crystal to settle on TX. Until this happens I usually get drift. Surprisingly, G8LCO (58km) has already spotted me a couple of times, albeit with drift - this drift should disappear before 1800z.

UPDATE 1750z: The transverter crystal has settled and drift on TX is now zero. M0FMT (51km) now copied on RX.
