Rf Bandpass Filters Based On Toko Inductors

Transcript

Info on creating RF bandpass filters using the Toko brand of inductors/transformer cans that can be obtained via mouser/digikey or salvaged for free from older transistor radios. Because there isn't a universally implemented/industry-wide standard color code, the more info we can compile to make identification of these variable inductance transformers easy, the easier it becomes to salvage and use them for our own RF circuit designs. I hope someone finds this article useful. All credit to original author.
