Hi John,

Did you actually turn off the main breaker in your house? Many times there are overlooked noise sources like cell phone chargers, etc that get overlooked if you just turn appliances off.

Paul, killed everything in my house, and it is still there. Will see what else i can do.I am dealing with some Power-line interference also, but that is being taken care of hopefully. I welcome any suggestions from all. 73 John W9RPM

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.
