It's switch mode. To localize, start by killing power in your residence.  If it 
remains, you must then triangulate the switching source with a directional 
antenna and portable receiver.  In lieu of triangulation, you can walk the 
site, noting changes in signal strength but that can be extremely time 
consuming.  Be mindful of false results due to re-radiation of the source. 

With so many switch-mode sources today, there's no sense trying to figure out 
what it "could" be.
