Nobody said 4 MHz is 6.6 MHz. 4 MHz is 60% of 6.6 MHz
and is therefore near 6.6 MHz. Dr. Corum says the
lumped constant model fails at 0.04 wavelength. In his
other paper, he says if the length of the wire used to
wind the coil is 0.06 wavelength, it's time to switch
over to the distributed network model. A 75m bugcatcher
coil uses more than 0.06 wavelength of wire.

Please explain the physics behind the velocity factor
of a coil changing radically just because you cut it
in half - assuming all other parameters are kept at
the same value.

Your model is known to fail at a point but you guys
have no clue where that failure point is. You just
have faith that you will never reach the failure point.
But what if you have already reached it?
