At about 0914z, I turned on my 10m QRP FT8 with 2.5W and the tiny indoor loop antenna. G0FWX (160km) copied immediately.
I have gone back to the thinner loop wire as I was a bit concerned that the higher RF voltages with the copper pipe inductor, although higher Q and more efficient, could have damaged the matching parts on TX.
UPDATE 1308z: 3 stations spotted with the furthermost OH6EJD (1874km). Nobody has spotted me. I think this is Es.
