How would I best eliminate engine noise while listening to SW?

This might have already been mentioned to you Al, but I know from experience
on this one.

First, go with batteries and the best SW antenna (which most won't go to this
extreme) is a 108in. steel whip. ;-)

There's other antenna setups you can use in a car, I've tried em' all. Steel
whip hands down wins.
