Topband: help identify noise

I know it's only partially 160m related, but I figured you folks have dealt with 
all kind of noises and perhaps one of you would have heard this one before.

I hear it on 1.923mhz or so but only that one frequency on the whole 160m band.

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

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 160m one.
