Funny, but incorrect. This mostly has to do with spurious RF noise generated by badly engineered devices like power supplies or manual light dimmer switches - things that aren't designed to communicate. Manufacturers are supposed to test for these sorts of emissions, but frequently don't.

Meaning you're claiming in a cities NYC & DC that the NSA doesn't to full spectrum dumps, right? Or that they would have not looked into statistically unusual high amounts of background noise?

If the NSA does this, they'd have the info. If they don't, I'd be curious why; meaning legal, physical limits, etc.
