[Elecraft] OT: Ferrite Identification Question

[James Bennett]

A bit off-thread, but sorta related, as these things ARE used for antennas with my K3/KX3!! I have a bunch of ferrites - donuts, clamp-ons, beads, etc. that I’m trying to identify the mix. With the guidance of Tom/W8JI I’ve figured out how to use my AIM-4170C analyzer to show at what frequency these things have an R=X value with Q=1. However, I’ve not been successful relating that frequency data to the mix number. An email to Fair Rite has gone unanswered, and trying to wade through their web site is mind-boggling. Does anyone on this list have a URL that points to this information?

Thanks, Jim / W6JHB
