Don,

Unless technology has very recently leap frogged (once again), I never believed that the Mikohn chips contained an IC (integrated chip), but instead had a detectible "load". Your antenna thought certainly qualifies. So would a magnet, or a radio active particle, or etc.

When we mention an IC, that IC can only do something if it has power applied to it. That means a battery, or an inductance capability, or something really advanced. In which case face value (and present TCR values) are well below actual worth.

I could be wrong, but the cheapest technology possible (for what these and the overall system did) is to "load" each chip with a foil spiral that is "tuned" to produce a correct harmonic when it is stimulated with an RF signal and then have a receiver set to that harmonic.

I wonder what the radiation level of the transmitter was like at those tables. Was it worse that a cell phone? Could it produce cancer of something and what would that something be?

Maybe a mediacl search for the early dealers should be made, they might be dropping like flies by now.

Anyway, I'd love to see the inside of one if any body has pictures.
