This is very true! The AADE unit measures at something like 50kHz
ranging to 600 or so kHz, and the characteristics of the toroid
material matters a lot getting up into the HF range. I didn't get my
AADE to measure toroids at all, but rather to check other components
and well, fool around with loop antennas, goofy homemade capacitor
ideas, that kind of thing. And of course it's good to be able to check
fixed components to make sure I've picked up the right one...... 73 de

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.
