After a break of a few days, I am again on 17m FT8 QRP with 2.5W and the tiny indoor loop antenna on the shack windowsill. It is now 1455z. So far, in about 10 minutes, 18 stations have been spotted on RX and my QRP has been copied by nobody yet on TX.
UPDATE 1542z: So far, 30 stations have been spotted on RX on 5 continents and nobody has spotted me on TX yet today.
UPDATE 1800z: 43 stations spotted on RX and nobody spotted my QRP on TX. QRT soon.
