A single-file software-defined radio receiver that runs entirely in a Chromium-based browser via WebUSB, requiring no installation, no internet, and no admin rights—just an RTL-SDR stick, an antenna, and `index.html` on a USB drive. The project is designed for offline and remote use cases, such as field expeditions, emergency kits, and locked-down computers, supporting FM stereo with RDS, shortwave, airband, PMR446, and general coverage from 100 kHz to 1.766 MHz.
- Decodes weather fax, Morse code (auto speed detection), and RDS, with an "Identify" menu that optionally queries shortwave.live or a web search for the tuned frequency.
- Includes a Panorama feature that sweeps up to 10 MHz at once and stitches the slices together for a wideband view.
- Built using Jacobo Tarrío's `webrtlsdr` and `signals` libraries (from the original Google Radio Receiver Chrome app), bundled into one file with esbuild.
- The US National Weather Service proposed closing its five HF radiofax stations in late 2026.
- Demo mode is available without a stick by opening `index.html?demo`, which simulates stations including FM stereo with RDS, fading shortwave, SSB, Morse, and weather fax.

Project N.O.M.A.D. is a self-contained, offline-first knowledge and education server designed to provide critical tools, knowledge, and AI capabilities regardless of internet connectivity. It's installable on Debian-based systems and accessible through a browser interface. The project includes features like an AI chat powered by Ollama, an offline information library via Kiwix, an education platform using Khan Academy and Kolibri, and data tools like CyberChef.
It aims to be a comprehensive resource for learning, data analysis, and offline access to vital information.
