Lots of over pole fading? Gwad knows what it is?

Sounds like something evil from China? That rapid fading is POLAR
Still strong with some lighter fades in SE USA. It can't be URO because even meg stations can't get over the pond now.
So, I may someday go to LOWES and build a crude DF loop.
I wouldn't rule out ASIA unless its still readable in a few hours, then it obviously much closer.
Lots of CIA crap etc in the band and I am told numbers stations, dumb as they are, often come from CIA in Maryland.
I did catch one about 4 years ago. It was only 1 pm and the carrier blew out my RF section.
