It seems to me that, when conditions are good, very little power is needed to be spotted on WSPR. I tried 10m WSPR with 500uW and was spotted in the USA. I tried running legal ISM powers on 22m and, again was spotted widely.
What's next?
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.
