Hi Max,
Have you looked at Carl's report on the RT Examiner? There is no hi-impedance amplifier inside the plastic case. There is just a jumbled collection of bits and pieces soldered together and hot glued in place.
If you place the leads of a digital multimeter close to a calculator, there is no pickup whatsoever, as long as you move away from these two items, and allow the readings to stabilize (to zero).
Well done J_P on an excellent description of what's really going on here.
There is definitely some electromagnetic interference (EMI) coming from the calculator, and this can indeed be detected by a small coil connected to an amplifier. However, this is not the case with the Examiner, which has been sadly totally misunderstood by Hung, unless (of course) you confer with the idea that the standard Maxwell-Heaviside model is erroneous because it omits the spin resonance.
