[TowerTalk] Cores

[Arnie Pfingst]

I frequently read about different mixture of ferrite used to make cores used for different frequency. Over the years I managed to accumulate a box of different cores. There are lots of different colors, from light yellow you purple, sizes ranging from 3\8 to 4 inch, and shapes from simple round to square and lots in between. How can I tell them apart. Arnie Kd6cz
