Since AM radio in the US and Canada is now mostly talk, today's radio manufacturers probably don't see the sense in designing the AM section of AM/FM radios for high fidelity; the FM in most of these is probably not much better. I have a "Windsor" branded AM-FM clock radio that works well enough in my area (a small town about 40 miles from most Cleveland radio stations), but the AM isn't much better than a glorified crystal set. When I lived in the suburbs, I once had a Zenith integrated stereo system with an AM tuner that was so bad I was actually getting short wave around 1000 kHz at night; that system's tuner must have been as cheaply designed as the one in my clock radio, although the latter at least doesn't turn itself into a shortwave receiver after dark. Maybe living in a small town well outside greater Cleveland, with its much weaker radio signals, has something to do with it.
