Malcolm, 

I have seen several references to a physical 1/4 wavelength of wire
being used to wind a secondary. What is the 1/4 wave length based on?
Is it free space or based on some velocity factor? Is there some magic
to be had by striving for this.

Based on no facts at all my next secondary will have a H/D ratio of PI.
It just seems right.
