Metal Detector Experiment

I designed a new metal detector today -- or tried to. It probably is a first, because it combines principles of radio reception with metal detecting. It worked first time, but not quite as I expected it to. It was supposed to produce a clean square wave at the output, but seems to be producing something more complicated (I didn't yet have time to "look inside" with an oscilloscope).
