was winding.
This comes up once in a while, and for the benefit of those (like
Stephanie) who may not have seen it before:
The measured inductance of a toroid depends on the frequency at which
it's measured because of the characteristics of the toroid material. I
don't know the frequency used by the AADE unit, but if it's far from the
operating frequency of a particular toroid, the results might be misleading.
Elecraft has said that they do *not* recommend meauring toroid
inductance, just winding the specified number of turns.
If you must measure the inductance of a toroid, it would be better to
use something like an antenna analyzer which will allow you to select
the frequency at which the measurement is made.
