UPDATE 1445z: 16 stations have spotted me today, including several in mainland Europe. See map.My 500mW beacon has been on since just before breakfast. Just EA8BFK (2880km) spotting me multiple times. I assume this is F2 propagation.

UPDATE 1855z: 23 stations have spotted me today. See table.
One of my Facebook memories today was the circuit for my 10m WSPR RX on which my 10m FT8 RX was based. See my website for details.
Since returning home again from Malta this afternoon, I have been on 10m QRP WSPR with my little beacon. Already spotted by 5 stations with the furthermost the German research station in Antarctica.
This is this evening starting at 1900z. I usually go on for a short time with 10W to the 2m big-wheel.
UPDATE 1956z: I did not stay on long, but worked 3 stations with the furthermost G4CLA (105km). It was a miserable evening with lots of rain.
I can only speak from personal experience. My transverter produces about 10W into 50 ohms and gave about 10mW ERP into my earth-electrode antenna in the ground. My earths are about 10m apart. It has been received on WSPR as far away as Finland and I got spotted in Norway most nights. It was in QST about 10 years ago. It is also described on my website.
This evening starting at 1900z is the 70cm FT8 activity contest. It always surprises me how far away stations can be copied. I usually work...
