Re: [EVGRAY] Coils cw or ccw. Instead use dot convention.

Norm,

How did you perceive output from this experiment if you collapsed the E
and B vectors to 0 ?     In the EH antenna literature they talk about a
system like this (the Russian predecessor to the EH) where two
transceivers can communicate on an otherwise hidden channel.
