Cecil: that's a VERY significant result. If I feed the dimensions of
W8JI's coil into Equation 32 in the Corum Bros paper it predicts an
axial Velocity Factor of 0.033. That would equate to a time delay of
24.7nS across the 10" long coil !!!!

Hi Steve,

You're right. The numbers are amazingly close - almost as if his
'experimental apparatus' had calculated the result rather than measure it.
