As usual, I have been on 10m WSPR TX (500mW) since breakfast. Es has been good with widespread reports from around Europe.
UPDATE 1458z: SM5ISM (1288km) remains my best DX on 10m WSPR TX today.
UPDATE 1640z: DJ9PC/1 (825km) has received me at an astounding +7dB S/N. Es! Assuming a low noise floor, uW power levels would be enough.
UPDATE 2126z: 22 unique stations spotted on 10m WSPR today.
