Fast propagation research with FT8

I think it is now evident FT8 is the most interesting digimode today for research of realtime propagation. And it is fast! Really fast! However for good research you need to receive and to transmit as propagation is not always reciproke. My idea was:

Start at band 10m and first receive 2x 15sec. timeslots to see were you can transmit in the waterfall. Then 3x transmit 15sec and 3x receive 15sec, In total 120sec=2 minutes in total for each band.
You can scan 10m-160m in 10x2=20 minutes and you got an idea how bands are at that moment.

Well, I can tell those 20 minutes became longer after all when I started this experiment as I used CQ for transmission and got stations back to me on some bands. Besides that I noticed 5T2AI from Mauritania on 20m FT8 with a strong signal which would be a new one for me. So I returned to 20m before I made the screenshots and worked 5T2AI for a second ATNO this year.

A overview from about 18:00 UTC yesterday evening:

Complete picture all bands

10m, I immidiatly had response. But no DX propagation.

12m, nothing at all. PSK reporter comes back with all stations monitoring 12m at that time.

15m, I didn't hear anything but they heard me! Typical non reciproke propagation.

17m

20m looks good but I was here about 30 minutes.

30m

40m

60m

80m

160m

All transmissions done with 25W. Except 60m were 15W is the legal limit. Antenna still is the coppertape multiband vertical at 9m agl.
