No problem on winding turns, and thanks!!! I will tune the ferrite to
24 MHz., and see how that works... I am setting up a test jig to hold
a ferrite out in the closest I can get to free space, being fed as it
would be in the real world. I will adjust the resonant frequency to
be 24 MHz., that should give me the best shot at using this to kill
this mess... THANKS again!
I'd be surprised if you could get enough turns on it to resonate, unless
it's a really big core. If it does resonate, the Q should be very low,
as that material is supposed to be lossy. (A pure reactance might just
reflect the current to radiate from somewhere else, rather than turn it
into heat.) There may be published curves for the core showing impedance
vs frequency for various number of turns. In any case, you want the
maximum impedance you can get at that frequency, and it should be mostly
resistive.
