I love it! My mind keeps drifting to a line of thought which revolves around the question: can a TC secondary supply useful information about its surroundings by virtue of its spatially distributed resonance at multiple frequencies. If so, what are the applications, eg, could a resonating solenoid lowered down a borehole return data on the surround rock, etc?

Another coil in the area was removed to avoid spurious coupling. Perhaps there is another resonanced formed somewhere, eg the TV antenna downlead, a loop in the ring main, etc. > Does q3 itself seem abnormal with regard to expectation? Seems normal enough in other respects. -- Paul Nicholson, --
