Even though the SWR was too high to TX, I decided to take a look at 40m FT8 with the earth-electrode "antenna" on RX. It is now 1849z and already 117 stations have been spotted with the furthermost UA9MA (4598km) in Omsk. This was after just a few minutes.
UPDATE 1930z: 276 stations have been spotted so far on 40m FT8 RX.
UPDATE 2107z: 505 stations spotted so far on 40m.
