Trailer AM radio reception

When I was a boy, my grandmother gave me a crystal set that had belonged to my great-grandfather. My father showed me how to hook it up. It was right beside my bed so I used to listen to it at night(when I was supposed to be sleeping). I used to listen to Arnie (Woo Woo) Ginsburg from a station that I think originated in Fort Wayne Indiana. The remarkable thing is that I was on the east cost in Massachusetts! The other remarkable thing is that a crystal set has no external power source; it operates solely from the RF input coming via the antenna.

But to get back to the original question. I think AM radio is a nearly forgotten step-child. None of the radios I currently own including the one in my camper get AM reception worth listening too.
