At 0806z, I turned on my tiny 10m WSPR beacon designed by W5OLF. Although 100% TX, this changes frequency randomly every slot to prevent being clobbered by a mega-station.
So far just spots by local G4KPX (14km).
UPDATE 1030z: A single spot by OH6BG (1718km).
UPDATE 1140z: Now spots by 3 unique stations (see photo). G4KPX has spotted me 101 times!
