in Questions, Spooky

Of ferrite cores & fairies

If we start with the intriguing proposition that there is potentially *some kind* of underlying waveform nature to reality (without getting too “quantum”), exploring RF can become a bit spooky. Which for me makes some of the more dry “sciencey” parts of it more compelling.

Take question on, which is part of the Canadian Basic Qualification:

“What devices would you install to reduce or eliminate interference to home entertainment systems?”
Answer: Coils on ferrite cores.

Here’s what looks like a decent sciencey explanation of that by a ham.

Basically, they suppress high frequency noise / interference somehow or other. One day I’d like to know everything about radio, but for now I’ll settle for Wikipedia, since my goal here isn’t to hamsplain but to hamsplore. A lot of people know the answers, but fewer still maybe know the “right questions.” (Trust me that’s “really profound.”)

And for me, the right question, right now, is: is there some practical link which we could draw between the scientific action we know ferrite core has against HF interference and some of the folklore surrounding iron and “alternative entities” (AE) and it’s effects on them? I mean, maybe there’s not, but it seems like a hella weird coincidence…
Again, I’m not a fancy folklorist, but I know how to search on Wikipedia:
“Cold iron” is historically believed to repel, contain, or harm ghosts, fairies, witches, and other malevolent supernatural creatures.
There’s an argument there that “cold iron” has never felt the heat of a forge nor been shaped by human hands. Something something.
“Surrounding a cemetery with an iron fence was thought to contain the souls of the dead.”
But like, let’s posit for a minute that fairies, ghosts — uh, maybe to a certain extent “witches” (though, this is getting complex) — are operating on / tuned to “other frequencies” which maybe let’s say ‘normal humans’ perceptual systems can’t completely demodulate. In other words, there are societally ‘normal’ bands of perception which we more or less can agree are “actual reality” and then there are like sidebands or whatever of reality… If you could tweak the receiver / tune the antenna (eg. perceptual system) / dial in the frequency, perhaps you’d be able to extract different intelligence out of let’s say, uh, paranormal meta-signals (without going too “meta”).

So like, iron could suppress those outsider paranormal frequencies, to prevent them from interfering with human perception. Are ghosts EMI?


Anyone who’s stared at a static-y TV or listened to the hiss of AM radio will recognize that there is something spooky out there in the noise.

I guess one way to tentatively try to “test” this idea that AEs are impacted by iron would be to (1) find a ghost or fairy or whatever, (2) find some iron, and make observations based on the proximity of the two and the effects over time.

Easier said than done, I guess.

I’ll leave you with one parting shot: one elf shot, that is.

Elfshot or elf-shot is a medical condition described in Anglo-Saxon medical texts, notably Wið færstice, and believed to be caused by invisible elves shooting invisible arrows at a person or animal, causing sudden shooting pains localised to a particular area of the body.

Makes you wonder — if you think about it:

“(A). RF energy can heat body tissue and cause burns. It is important to use proper precautions against excessive exposure to high amounts of RF energy.” (

Just sayin’: “Invisible arrows” sound a little like RF radiation, no?
