I'm about 1100 miles out, and I do get destructive interference
sometimes for a few minutes around sunrise. But this lasted for over 12
hours and the "lock" indicators were still on when it was happening.
I've never seen anything like this before.
When I have some time later today I'll figure out what the delay would
be on a one-hop path versus the groundwave path, though I suspect the
difference isn't as great as I'm seeing.
