  • Below the Noise Floor Presents: The Trojan Relay (A Dramatized Special)
    2026/06/05
    A dramatized audio mystery. It starts the way these things always start. Late, alone, tuning the dead grass at the bottom of the band where nothing is supposed to live. Then the static stops in one narrow place, and starts counting. The carrier does not drift. It does not move with the stars. It holds station against the Sun and the planets both, from the one place in the solar system a thing can sit forever and never spend a drop of fuel. The payload is a wall, packed so tight it reads as pure noise, unbreakable. But the operator does not need to break it. He reads the headers. The addresses, the hop counts, the timestamps. And the envelope tells him everything: the size of the network, the reach of it, and the one universal clock its builders used to stamp the very first packet. The answer to how old they are is not the scary part. The scary part is what arrives on the second night. Best experienced with headphones, in the dark, with the volume up. Contains: one carrier, one operator, and a question with an answer none of us were ready for. A Below the Noise Floor dramatized special.

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.
