HB9UF: Desense Testing

This video is part of the series in which I show some of the things I encountered while building a ham radio repeater. The whole series is available here:    • HB9UF   In this video I first discuss the cavity resonators that I use to build the duplexer. This is not a tutorial though, those duplexers are probably one of the more complicated things and I strongly suggest some solid reading to get the information that I cannot provide in video form. The second part of the video shows how I perform a desense test on the repeater.
