9:1 Balun Experiment – Does Core Choice Matter?
291Join me, Steve (KM9G), as I dive into the world of 9:1 ununs with an unconventional core! My friend Ziggy sent over a minty green toroid, and we're testing whether it holds up against the traditional cores used in ham radio builds.
🔍 What You'll Learn in This Video:
✅ The science behind 9:1 ununs and core selection
✅ How different toroids impact performance
✅ A real-world antenna test in the rain 🌧 ️
✅ SWR results across multiple bands
✅ LIVE FT8 contacts—including a 5W QRP DX to St. Helena!
🚀 Can you really make a 9:1 work with any core? Let's experiment and find out!
