Interesting Jay, thanks for the input.Local Noise yeah.... The locals distinguished radio guys were complaining about bacon sizzling type noise all over the bands and all over the place location wise.
I built a crude magnetic loop and antenna and drove all over the place figuring it was power line noise or something inducing noise into the power lines. I found that when I was underneath the High Voltage Lines I could hear the noise louder. These High Voltage Lines are the highest power lines on the poles and on steel towers.
I could not pin point or DF ( Direction Find ) the noise, as it was every were/direction. I am sure many who drove by while I was trying to DF the noise thought I was a looney, use to that.
So maybe it was solar noise of some sort. It only lasted a few weeks ragging havoc on all the HF Bands. Many dropped their antenna and looked them over, some even changed their coax. I drove all over even out into the Mojave Desert and still could hear it. Maybe a high voltage problem some were or solar noise, I just don't know.

I know when it rains, the noise is gone so its not back scatter
