A short common mode current chokes comparison, trying to decide which one is better. I picked the coaxial cable version and the insulated copper wire version for this test as they are more common and easy to make. I only had the FT 140-43 toroid available. I would recommend the 31 material instead ( FT 140-31 or even better FT 240-31 ).

Videos on homebrew amateur radio gear that will hopefully inspire you into crafting your own unique radio projects.
I am passionate about amateur radio since childhood. I got back into the hobby in 2016, while living aboard my sailboat. I received my license in 2022 as YO6DXE. I use mostly QRP equipment experimenting with all modes, but I prefer CW or SSB.
