10m FT8

Trying to compare 10m WSPR with 10m FT8 is difficult. On WSPR I can use my stand-alone 500mW WSPR beacon without the PC, whereas for FT8 I have to use the FT871ND and the PC. In both cases the antenna is the indoor loop.

Today, I am on 10m FT8 using the FT817ND and the indoor loop. Power is 2.5W. So far (0820z) I have been spotted by no-one at all. On 10m FT8 RX a couple of Spanish stations have been spotted.

UPDATE 0840z:  One QSO so far and 1 spot of me from northern Spain. On 10m FT8 RX, 8 stations spotted with best DX being UA9CAW (3817km).

Stations spotting me on
10m FT8 TX today with 2.5W 
UPDATE  1922z: So far today, 60 stations have spotted my 2.5W 10m FT8 to the indoor loop. With already nearly 5 times more stations spotting me on FT8, I conclude that FT8 seems to have largely replaced WSPR as a weak signal mode.  WSPR is about 10dB better than FT8, and the power level I use of FT8 is less than 10dB more.

UPDATE 2038z:   Now 70 stations have spotted me.

UPDATE 2130z:   73 stations have spotted me. On 10m FT8 RX 6 South Americans spotted with best DX spotted CE4WJK (11814km). In total, 373 stations spotted. Soon be time to go QRT.
