Well...my 2010 Outback and 2014 Acura TL both hear powerline noise
fine. Clearly there's variation by manufacturer, but it's easy enough
to test - just drive down the road alongside a power line.

Hi Pete,
There is some truth around car AM radios being a poor choice. I
was experiencing S9 noise on 160 meters that turned out to be 1.07
miles away and my old 1976 Saturn Wagon AM radio could hear the
noise over .75 miles away and it allowed me to get within a short
distance from the source and I told the owners of the property to
just tune to 1710 and they would easily hear it too. Guess what,
they could not hear the interference with their modem car AM radio
whereas the interference was blowing away my car radio with both
cars sitting next to each other right by the arcing power pole.
I suspect a lot of the newer car radios have excellent pulse noise
reduction. My old Kenwood TS180s noise blanket kills power line
noise too(except during contests when the band is loaded with
strong signals).
P.S. My Saturn turned over 250,000 miles last week, and still
going strong including it's old AM radio that is great for power
line noise detection.

Don (wd8dsb)

I couldn't agree less... I've been using my car radio to close
in on noisy poles for a decade and more. Tune to the top end
of the AM band and drive. Get close and take a portable radio
from there.
The local electric utility's RFI guy wants to do a good job,
and has decent equipment but doesn't know how to use it. Last
time he was floundering around with a receiver set around 100
MHz with a hand-held log periodic that from its size probably
started about 300 MHz.
Next time I see him I'm going to urge one of Mike's RFI courses.

Due to the noises produced by cars, their radios are
probably the most
heavily suppressed in the world. Rule #1. NEVER use a
car radio to try to
hear or find noise.
