Build Your Own Radio (Even as a Beginner) – Homebrew Ham Radio with ZL2BNE
Neville Marr, ZL2BNE, is a New Zealand amateur radio operator known for turning homebrew radio into something approachable and practical. He’s designed and shared projects like a 40-meter SDR receiver kit and regularly operates using self-built SDR transceivers, including the T41 platform. Along the way, he’s supported wider ham radio initiatives such as Reverse Beacon Network stations, and today he helps inspire others to get started building and experimenting with their own gear.

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.
