Having spent over 45 years recording sound, I agree that the signal level
decrease is real. And easy to see on good recording software.

With tongue in cheek, I say that I think that the ionosphere gets
overloaded after a few characters. 160m ionosphere is somewhet delicate at
best.
I do, however, notice this effect in most HF contests, and it's always the
weak sigs that suffer, of course, as a few db at the lower levels makes a
BIG difference.
