In this video, Dan Koellen (AI6XG) shares the stories behind some of his most creative homebrew radio and electronics projects.

Dan has spent years building, modifying, and perfecting gear for ham radio, portable operations like SOTA (Summits On The Air), and experimental electronics. From modified QRP rigs and custom vacuum-tube transmitters to clever antenna transformers and portable stations, this is a look at some of his work.
