Ron's right, and I'm repeating myself too, but I want to add that the
effect of a toroid core on inductance *varies with frequency*. So if
you have an inductance meter that uses a 1 MHz signal source to measure
the inductance of a coil that is to be used at 10 MHz, the error may be
quite large.
I have used an MFJ antenna analyzer to measure toroid inductance at the
relevant frequency, but as Ron points out it is not necessary or
appropriate to do this when winding toroids for an Elecraft kit.
