I tune between stations on the AM band when I drive around looking. Of course,
holding a SW portable out the window works, too, and allows getting out and
confirming the source. You'll note that the noise tends to rise and fall along
the lines due to, I believe, harmonics.

If the noise is internittent, check out the pole transformers and street
lights.

I don't like my Ford for the same reason. I believe Chrysler is the only one
that fully bonds everything without special order. At least they used to. Else,
ask for the police bonding package.

I tried driving around with my DX396 and noticed one place, about a half
mile from here, where there's a loud pop! pop! pop! noise on all bands.
I was unable to get the pole number since the pole is on private
property like most power poles in the area. I DO have the street
address. The popping fades up when driving to this one spot and fades
down when driving away.
