open air coil completely shielded with tin plate, effects on the frequency
Old upload ( 6 september 2008) from my former channel, Radioam232. The effects when a open air coil (without a ferrite rod in it) is completely shielded with tin plate. The frequency goes up substantially. Keep it in mind when designing (e.g.) and building IF coils by yourself, take the higher frequency in reality in account. More electronics in my books on the Lulu website, author Ko Tilman.

In thematic order you can find these video’s under the “comments” section. My books about electronics are available via the website from “Lulu”, search for author “Ko Tilman” there.

My books are also available via Barnes and Noble and via Amazon. Regarding all my video’s: I constantly keep them actual, so the original video’s with the most recent information are always on YouTube. That is the source, and search there. When my video’s are reproduced or re-edited on other websites/channels you can not (!) be sure about the original content (=really working electronics) and important adaptations to the circuits.
Be aware of that, I saw on the internet many of my circuits reproduced in a poor or even not proper way. I can not help that, sorry.
