Leaving 6m WSPR on overnight was a waste: apart from local G4IKZ (18km) only 1 spot of me by G8JNJ/A (184km) and no Es seen here on 6m WSPR at all.
At 0856z I QSYed back to 10m where I was immediately spotted by OK2RO (1282km) several times at good strength. I have also spotted him. 10m is definitely a more productive band for Es.
Sunspot count today is 139 and 20-30MHz is forecast to be "good", so some 10m F2 propagation should be expected later.
