EXACTLY! You don't have one noise source, you have dozens of them.

If you want a fast education on the noise environment, find a VHF/UHF 
mobile rig that can receive AM, program it for frequencies around 
150-160 MHz, 300 MHz, 400 MHz, and 500 MHz, and drive around listening 
to it. I live in the Santa Cruz Mountains, closest house about 300 ft 
from my antennas, most houses at least twice that distance. As I drive 
around out in the country listening on 160 MHz, I hear noisy power lines 
and occasional noise sources in homes, but there are lots of places 
where it's RF quiet. As I drive into town, even a small town, noise is 
everywhere.

Those UHF frequencies help me zero in on a broadband source like a power 
line arcing -- when I hear it at 500 MHz, I know I'm real close. I'm 
using a Kenwood TM-V71A mobile rig, and a TH-F6A talkie, both of which 
can receive AM in this range. I don't know what other rigs have this 
capability.
