I'm lucky, I guess. As a software engineer who programs remote crane(mostly) control systems I've got a BIG desk (essentially 2 at right angles) to lay all the gear I have to test my work with out on. Keeping my Zenith C835H ~3'-4' away from my laptop results in clean reception (except when I set up a remote next to it) on Am and FM with the loop...I've got metal cubes around me too, but am against a cinder block wall on the side most of the good locals come from so there is not much it need filter through....
I don't run it much though since I don't want to bug my cow-orkers.
Interesting how a simple set shines in a difficult location like that.
