It seems perfectly feasible to me, but the earthing is as important as the coil. I've received a signal using a flat spiral coil, and what's more, the signal of the normal radio receiver gets stronger when the coil is being used. It becomes a passive repeater. The radio station is already powering your earphone, so what limits the amount of energy that you're receiving? I built the simple SEC circuit once but I've never had much interest in that sort of thing. Where do they connect the output of the secondary? ...
