60 HZ hum on AM car radio near powerlines - any ideas

[Bob F]

I've tried connecting ground wires to the body from the antenna shield near the
radio, or the metal cap/nut that tightens the antenna into the body, with no
affect. I still get real obnoxious hum whenever I am near powerlines. Has anyone
here had and solved this problem?

The radio is a Pioneer "supertuner" AM/FM/CD unit.

Don't listen to AM near powerlines.

Seriously, it's called "interference" and you can't really address it at
the receiving end.

Seriously, why didn't every other car I've had had this problem?
