I am interested in what empirical evidence can be had to determine how much power is "as much as you need to make the contact."
This FT8 sequence seems to be one of those data points. I tried for a while to get this Chilean station and then someone from my grid square swoops in to get the QSO!
Recently went from a 25W rig to a 5W rig. Fewer QSOs and more incomplete exchanges, though I know the bands have been rough.
