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.
A few days ago I tried spotting on 137kHz WSPR. Nothing was copied.
I am wondering what modes are used mostly these days on this band? Perhaps WSPR is less popular on 137kHz than it once was.
