I don't use the AADE meter (my inductance meter was scratch-built from the
ARRL handbook) but the fundamental frequency of the signal is not what the
inductor is reacting to in most modern designs
The one I use, which I believe is similar to the AADE in measurement
methodology, applies a square w
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

Thanks for mentioning that Vic,
I have seen that in the Elecraft manuals and I don't expect the
inductance I measure to be exact to what the schematics call for.
It's just nice to see that it's close. Especially when there might
be some confusion about the cores, when they look similar.

With all this talk about the $100 AADE LC Meter, I thought you'd get
a kick out of this. It's only $13,000!

Hi Alex:
Gotta agree with you... the AADE LC meter is a FINE addition to any
ham tool box. Though I don't use mine extensively, it do manage to
find sues for it on a fairly regular basis and it never ceases to
come thru for me. For the price, it'd be difficult to beat.
Another device you mig
I 've also got an AADE LC meter (our club's Project Day from last
spring, a dozen of us built them) and I can also vouch for it. It's
a fine meter, was fairly easy to build, and is very easy to use. I
used it quite a bit while building my K1 and K2, to verify the values
