60 Hz noise on car radio from powerlines

I recently acquired a 1994 Dodge Caravan with a pioneer supertuner AM/FM radio.
It has bad problems on an AM staion I listen to whenever I am near powerlines.
There is a 60 Hz hum that modulates the audio causing bad distortion. I thought
this would be a grounding problem, and have tried adding an additional
temporary
ground at either end of the antenna cable, with no effect. Can anyone offer any
help in solving this?
Is it hum or buzz. I'm thinking buzz.
I don't think i ever encountered this, but power lines will emit
noise. Is the noise all across the band ?
A different type of antenna may help. I'm thinking a big loop on top of the roof.
