Walt,
I've noticed that weather conditions have as much effect as
solar/geomagnetic for overall reception and it varies with location.
What killed reception this morning, and is still fairly bad, is a cold
front moving in when the humidity is already low. After the winds die
down there still seems to be quite a charge in the upper atmosphere, I'm
guessing stratosphere or maybe the D layer picks up an induced charge.
Dunno for sure.
The noise level goes way up and more distant signals either aren't
reflected or are absorbed. Since right now my receiver and antennas are
going through almost daily changes I checked with my DX-440 and longwire
just to make sure I hadn't forgotten to solder or fried something.
The noise peak moves down in frequency as it clears. at 20:00 local WWV
at 5MHz is still noisier than usual but 10MHz is in the clear, better
than usual and 2.5 is buried in the mud. MW is still trashed and I
haven't bothered to check LW.
The only place I've noticed this pattern is in eastern SD and south
western MN. Maybe Rick down in Omaha has noticed the same thing or
someone in the prairie Provinces. Spring and fall are the most common
times for this to happen.
By morning at least the X-band should be clear

Right, Tim. What a difference a day makes, and what NOAA says about
propagation is of little value, it seems. A real crap shoot every
morning....going from one of my best mornings on Sunday, to one of the worst
on Monday. Go figure! ........Walt
