Measuring Common Mode Chokes - QSO Today Virtual Ham Expo, August 2021

This is the presentation I gave at the QSO Today Virtual Ham Expo, August 2021. Links to other, more Scientific, papers: Ward Silver, Nuts and Volts: https://www.nutsvolts.com/magazine/ar...

Original Description: There's a lot of literature on designing 1:1 baluns (more accurately: common mode chokes) in ideal situations. But what about non-ideal builds? They're often too complex to model and predict. But we can build and measure them directly, with the NanoVNA.
