It's something different. I used to tune in radios by waving my hands around the antenna like a theremin. Some people seem to throw off more of an electrical field than others. Yes, I am available for bizarre scientific experiments.
This comment made me smile - this is exactly what I did as a kid when my radio got static-y. Slightly changing my position with relation to the radio, without touching it, sometimes fixed it.
I have the same relationship with the cheap clock radio in my bedroom. It sounds great when I'm in bed (to the side of the radio), but as soon as I get out of bed (in front of it) I have to turn the damn thing off because the reception gets terrible.
I wonder if this means I shouldn't get the iPhone4? ;-)
