Listening to B11 B12 balloon on 434.500 MHz. Just with my vertical.
I was surprised to be spotted by ZL3PX Geoff (see photo) on 40m WSPR. Very nice, distance: 18.663 km. I was running 5W. Yesterday I experimenting with WSPR QRPp 50 mW on 20 meter. Best spot was LA9JO that's 39.300 km/W or 24.426 mpw. With such low power LA is DX!
