Below the Noise Floor
Below the Noise Floor is a self-education project turned podcast. One licensed amateur radio operator learning HF radio and AetherSDR from the ground up - the bands, the waterfall, the voice chain, the digital modes, the antennas - and sharing the process. These episodes are mostly AI-generated content built around real curiosity and real equipment. If you are new to HF or new to software-defined radio and want something that starts from zero and builds methodically, this might be exactly what you were looking for.
