The self-resonant frequency of the inductor is shown by a large rise in
time delay. Cecil is now trying to rewrite the self-resonant frequency
of the inductor I tested by using his own seriously flawed theories,
but despite the fact it appears to be clearly shown in the network
analyzer data at about 16 MHz.

Well then, if 10" is 1/4WL at 16 MHz, its velocity factor is 0.054.
10" on 4 MHz with a VF of 0.054 is 0.063WL or 22.6 degrees. Why
didn't you measure 22.6 degrees or 15.7 nS of delay?

You measured 3 nS or 4.32 degrees of delay. Something is obviously
wrong. The VF couldn't change by a factor of 5 to 1 going from 16
MHz to 4 Mhz.

I think I know what happened. You forgot and left the test wire
attached in parallel with the test coil. :-)
