diy IF transformers: first attempt.

[AdrianPH]

I struggle with coils, I tend to always test them in a circuit and see what results I then get, many a time I forget that my test gear is 50 Ohms so end up loading it badly. In the end I check up with articles that say how they had wound coils and what size formers, then guess if I need to go more or less.

I have only found one software calculator that I like, and that is from this site https://coil32.net/ I used it to compare my results with the EHT generator windings with calculated figures and managed to get somewhere close. Keep plugging along it is all part of the fun of the hobby.

I wonder about building a small FET amp and as a source follower and feed that to the scope with coil to the see https://www.electronics-notes.com/articl...ircuit.php

Crochet is way to complicated for me.
