Measuring loss in a high-Q resonant circuit is, indeed, very easy. I just loosely coupled the circuit to the tracking generator and input of a suitable spectrum analyzer and measured the center frequency and bandwidth.
By the way, some simple experiments with orienting the "knot" of the ty-wrap showed that the effect was due to voltage between wires, not the current flowing down the wire.
