After 1440z the ERP is now correct. My TX power (from the transverter) is actually about 12W but the measured ERP is very low (around 5mW) as the antenna is so poor. I measure antenna current and calculate the antenna's effective height.
UPDATE 1820z: I am still surprised how few G stations are active on TX on 472kHz. G6AVK and G3WCB have both been received this evening.
UPDATE 1945z: G4KPX has now come on and is being copied.
