Hi Jim,
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!

73, and thanks,
Dave (NK7Z)
