Just wondering if anyone has any tools/tips for hunting RFI.? Lately I have noticed S9 noise levels on some bands, though the noise appears

to be very wide-banded.? It is quite evident in the spectrum display when it is present, and seems to cover hf to 6 meters, but worst around the 10Mhz band.?

It will to last for hours and then maybe go away for hours, but when it is present, it will occasionally stop for a few seconds and then start back up.? I seems likely to be a power line arcing issue.

On my AM car radio, it seems to be worse both east and west of my house for maybe a ? to ? of a mile.? Hard to know for sure, as I only have the sound to judge.

I did try walking around with a HT at 137Mhz AM and a 2 meter 3 el yagi, but not much luck, or I didn't go far enough.
