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.

Below the Noise Floor — Episode 1: What HF Radio Actually Is
High frequency radio has been talking to the other side of the planet for over a hundred years. No servers, no cell towers, no infrastructure - just a transmitter, an antenna, and the ionosphere. This first episode covers what HF radio actually is, how skywave propagation works, the amateur license structure, and how software-defined radio has changed what is possible. Plus: a preview of the AetherSDR series coming next.
