Same old story, noise is not strictly limited to 40m, it's just that is where I 
have been doing my sleuthing trying to figure out what it actually is.
now for the next chapter, pics of the noise using Rocky and the panadapter on my 
K2 as well as mp3's of the new/old developments can be seen here:

It seems it may be connected to an old arcing noise that I had been chasing last 
summer.
============
here is what I said previously:
 > Subject: [RFI] 40m (and other) noise
 >
 > I have recently started hearing a noise 24/7 on 40m.
 > The noise is heard about every 11khz and randomly moves up or down a khz or so.
 > Best I can tell it covers from about 6.910mhz to 8.040mhz
 >
 > I also hear it on 1.923mhz or so but only that one frequency on the whole 
160m band.
 >
 > I just checked the 30m band and I hear it every 40khz on it.
 >
 > Can any one identify what it's coming from?
 >
 > It may show up other places,
 > I just ran into the 40m ones the last few days
 > and then tonight found the 30m and 160m one.
 >
 > I have shut down my apartment at the breaker panel,
 > and the noise is still there. I have had new neighbors move in an adjoining
 > apartment. Above and one apartment over, right below some of my antennas on the
 > roof.
