Something seems wrong to me in that the difference between reports I give and I get on 472kHz WSPR suggests either my ERP is higher than I think or the ERPs stated by some others is lower than they think. I am pretty sure my ERP is about right give or take a few dB "experimental error". I am able to measure antenna current, I know the actual antenna height and can calculate the effective height. If anything, I believe my ERP is over-stated as my losses are pretty high. I suppose my reports of others may be a few dB down because of the poor-ish sensitivity of my FT817 at 472-479kHz?
UPDATE 1740z: I have been on 472kHz WSPR for just over 1 hour now. Just the usual early evening reporters with some very decent reports from G3WCB (101km) and G8LCO (58km) amongst others. As always, PA3ABK/2 (306km) is putting in a big signal again this evening from across the North Sea.
UPDATE 1752z: Just been spotted in Wales by GW0EZY (251km) at -25dB S/N.
