So what does that mean for radio signal propigation (he asks unknowingly) , , ,
Do I buy that tower I’ve been dreaming of now or do I wait until others are unloading theirs?
We expect the short wave propagation (atmospheric rebound radiation) to continue to weaken. How long?
Can’t tell: The last time this happened (back in the early 1600’s) it lasted over 80 years. But nobody then had radios - except in the 1632 universe of Baen books! - and so there are no experiments to refute, or fute, theory.
