At the moment I am on 10m WSPR TX with my 500mW W5OLF beacon. Two spots by local G4KPX (14km) only so far.
UPDATE 1120z: Plenty of spots from G4KPX, but nobody else yet.
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.

I see it also supports beacon modes like WSPR. It is tiny.
They are also working on a tiny digital transceiver. I hope they make a 10m version. These days I mainly use FT8 and WSPR.

UPDATE 1647z: Just received a reply to my query. Hans is planning a version for the higher HF bands, but wants to catch up on the current version first! Parts supply is very difficult recently.
My gear has been on for about 40 minutes. At 1008z 67 stations had been spotted on RX with the furthermost ZS5TC (9604km).
