Why, like clockwork, does WFAN 660 NYC, received 500 miles west in

almost 7am now, for instance.

Not just a random once-in-a-while thing, but regularly.

Could be interference between skywaves reflecting off different layers,
and/or with different numbers of "hops."

It might be a slow lowering of the reflective height as the sun comes up on
the ionosphere, leading to a gap between one hop vs two hop coverage, and
nothing to do with absorption, I guess.

My puzzlement came from not seeing how absorption could be doing it. Maybe
it isn't and it's just geometry.
