This group is clearly one of the most technical groups around and if this
off topic enough, please kill it.
The question is that if you have a box of ferrites with no labels on them,
how could you measure their ability to be used as a choke. Yes, you could
measure them and look them up assuming they came from one vendor.
You have the usual ham tools plus a spectrum analyzer with a tracking
generator.
Does anyone have a tried and true method for determining what their choking
impedance might be?
