[Lowfer] Core material on monitor cables

[Andy - KU4XR]

Thanks Paul:

I have the pgm, and what you recommend sound like a logical
way to see what I have on hand.  From the best I can 
understand so far on this core stuff, just judging by the
color of the material, most of it is Ferrite which is good.
Next is determining its type, and optimum frequency of use.
Thanks for your input Paul; and 73 to you and yours :::
