[Elecraft] OT: Big Ferrite Split Beads @ B.G. Micro

[Jim Sheldon]

They didn't list the material type in the ad, so no, I don't.  I suspect they are surplus from a computer power supply manufacturer as they are about the same size as those used around the output leads of many of the switching supplies used in computers.

I've had several queries on this so I'm posting here - I have no idea what ferrite material is used in these cores and by the time the ones I ordered get here and I test them with my antenna analyzer and a 5 turn loop, they'll probably be sold out.
