Ken,
Take a look at the attached screenshot of the FairRite catalog... A is
the OD, B is the ID, and C is the length. Look at the second pair of
numbers from the left, numbers 3 and 4. That is typically the mix
number. You can take those numbers to the various vendors to see if
they have any. If the list strips the screenshot, send me an email
direct, and I will shoot you the data.
73, and thanks,
Dave (NK7Z)

I can find mix 43 and mix 71 beads, but so far, no mix 31. I even
tried eBay.
Hi Ken,
Dave and I have been good friends and collaborators for years, but I
strongly suggest that you study my work on HF chokes. His advice to use
#43 for HF suppression is wrong. While Dave has done a lot of excellent
work on identifying, chasing, and fixing RFI issues, my work on chokes
is FAR more extensive (since 2004) that any solid work I've seen
published. And the guys at Palomar don't have a clue -- they're just
selling stuff.
