Hi Ed and all,
I think I need to correct something from my last post. I don't think one
can get "almost unlimited" voltage from a receiving coil, even if its Q
approaches infinity. This is because the (reactive) currents in the coil
produce a magnetic flux which has to be taken into effect when the induced
voltage is calculated. So high Q's don't give much effect, after some
point, even unloaded. Have you heard of Sutton's (regenerative) "black hole
antenna", and the magnetic field plots?

I only started to try to tap the connections to the lamp. The 4 watt, 120V 
nightlight lamp was the highest resistance lamp I could find. I am
investigating another transmitter, as its (50-75 ohm) pi-network output did
not like to load to a resonant LC circuit, or a link - not really a
surprise!

points out they just different names for well-known phenomena and somehow
caught the attention of the as usual ignorant "science writers" with wild
and unrealistic claims.  In your experiment did you try tapping the lamp
down on the receiver coil in order to get best efficiency?  I would think
that would be necessary.
