As mentioned in the earlier post, I am on 10m QRP FT8 at the moment. At the peak of the solar cycle it is all too easy!
At solar minimum it will be very different as many will desert the band. In my view 10m would be good for DX at solar minimum far more often than we would have thought.
I really hope more stick with 10m, even 8m, FT8 for much longer so we can see.
One useful experiment would be to TX FT8 on 15m, 12m, 10m, 8m and 6m sequentially and see how many stations spot on each band over time. Ideally this should be carried out over several years around solar minimum. An antenna that covers all these bands would be needed.
