Re: Inexpensive source of ferrite for FSL not recommended for an LF FSL
Hi Steve,toggle quoted messageShow quoted text
Just came across this.
Kevin e-mailed yesterday, and I forwarded the .pdf file for the ferrite rods I am using, and upon which my writing is based - A2 Nickel/Zinc.
From the above chart I wonder if the initial permeability of my rods is circa 10,000. I feel that using these in a sleeve much better preserves useful permeability when compared to when used as a rod, or, in rod like multiples.
Last year I wrote about modding the antenna in my Tecsun PL-380.
The rods in my sleeves are the same as the rod I used for that !
They make the Tecsun perform almost as well as my Sangean does with its 8" rod !
I was tidying out my greenhouse yesterday when I realised that flower-pot saucers would make brilliant FS Loop formers. They have edge lips capable of aligning and holding rod ends in place, and come in a whole variety of diameters.
Maybe what is not apparent from looking at the FS Loop on its own - though it has always been stated right at the beginning of my written text as uploaded in the FS Loop file - is that the FS Loop was merely a bi-product proof of ferrite sleeve inductor quality.
I was optimising the ferrite sleeve inductor for another (Tesla based)purpose, NOT as a receiving loop, and this is why Chris Trask's comments here and via e-mail directly to me were not only so offensive to anyone who holds dear to Truth, but so totally off target when he accused me of copying Polydoroff's prior work, of which I knew nothing about!
My text IS heavy reading, and this is because it deliberately relates to 'hands-on' findings which current theory cannot explain. It also never ceases to amaze me how people contact me because they think I do not understand 'their' theory, but which I avoid because it *closes down essential thought processes*, and starts futile arguments and bad (often aggresively egocentric) feelings, which are an exact opposite of the free sharing we all need for progress and the sharing I witness in this group.
I have thus added two dated paragraphs for 14th and 16th March to the end of my writing, and invite memebers to read these.
Right at the end of the text is a 14th March dated postscript.
Also in final notes No 9, is a 16th March addition related to the real reason for my sleeve investigations, and my need to understand what happens within the primary electron orbit (magnetic) domains of ferrite. I feel it very important that everyone reads this 'final note' because really it is only a part of the beginning of something much more important, and provides a link to more recent like minded work I did not now existed and thus was unaware of whilst writing.
Cheers .......... Graham.
