AM nighttime bandscan video 3-6-12

That's one of the first things I noticed.  Radio Reloj on 570 and then CKWW on 580.  In SE Michigan, I don't know if I ever heard Radio Reloj.  My theory is that it is just enough weaker, and WKBN skywave is much stronger than the WKBN groundwave west of Cleveland.  I heard RR in Ohio before, though.

If you were using a directional receive antenna (loop or loopstick), in what azimuth plane was the null oriented?

I was using my car radio for these, however, in the first bandscan video I did on 3-6-12 my car was facing East. In the bandscan from 3-7-12 my car was facing North.
