This is the biggest amateur gathering in Europe, so I hope it takes place in person this year. No idea of the dates, although I am sure it will be on the internet somewhere.
UPDATE 1600z: Found it! See https://www.hamradio-friedrichshafen.de/
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.
