For small and medium quantities, WX0B. For large quantity ($500-$1,000
min order, buy only in box quantities), Fair-Rite or other
distributions listed on their website and in
of the tongue you may
never get over. Ben Franklin

I don't get it. I went to a LOT of trouble to write that tutorial, then
post a link to it in response to questions like this, tell people where
to look, and
Mike and all,
Loadstone quoted $5.4506 each for quantities of 1 to 249 pieces. They do have a
minimum order of $50. Very nice on the phone.
I'm ordering for our Tennessee Contest Group, so we will exceed the minimum by
a little bit ;o)
This should kill the last of the garbage on my 160M

Pretty simple Jim, I'm old ;o)
I probably have three copies of this tutorial printed in various locations, but
never where I need it when I have time to search.
On the other hand, I do recall the size and material of the item in question.
Usually that's an easy way to search for surplus
Thanks to all for the replies... Didn't quite get an answer to the -J versus
-31, but still useful.
Jim, ask for a quote from whom? WX0B or Fair-Rite?
Cheers,
Julius

I know there are several folks here who could answer this questions.
I'm looking to improve my current chokes for my 160 and 80 Tx antennas. I was
planning on going with -43 material, but after reading thought -J and/or -31
mixes might be a better solution.
The 31 mix seems a bit more
You might wish to experiment with Steward mix 35 or 40 toroids. Mix 35
has a relative permeability of 5000 and mix 40 is 10,000. Fair-Rite's 31
material has a relative permeability of 1500.
Digikey carries several sizes of toroid cores in mix 35 and 40 at
moderate price. Search DigiKey's web
I should also mention that Mouser carries some Fair-Rite mix 31 cores.
They are in the catalog at Fair-Rite --
http://www.mouser.com/catalog/637/917.pdf is the current catalog page.
