| Do you have a NanoVNA? Looking for new ways to use it? Mark, N6MTS created this great video presentation on common mode current and how to measure the effectiveness of a choke you build. Mark delivers a great explanation of what common mode current is and what the impacts are. He describes how to build a simple test jig to use your NanoVNA to measure the effectiveness of chokes we can build. Using his test jig he demonstrates a number of simple common mode chokes, and graphs their impedance at frequencies across the HF spectrum!
