Gary, I took a look at your satellite view. There sure seems to be potential for 
noise in what I see. Are those electric train tracks near your house? I can just
imagine the noise from an arcing power trolley. You might take note of when
the trains go by to see if it correlates to your noise.
   Also the noise as pointed out by someone else sounds a lot like a noise
I had here when two guy lines to anchors off adjacent power poles were
 actually touching in the center. As the wind blew or weather changed
 they rubbed causing S9 plus noises over a mile away. My power guy says
 that about 90% of his noise findings involve the ground wires and guy lines.

>I'm having a horrific level of QRM which seems to bother 160M and 30M 
the most. My inclination is it's a street light that is causing the 
noise as I often notice it at gray line times. I was working the ARRL 
160M contest and it started up around 11PM local time. It was 
sufficient to ruin any chance of QSOs during the contest so I taped 
it first with a 200Hz filter on CW and you can hear what it sounds 
>like to me. no file is more than 400k in size.
