RadioIntel is a software-defined radio monitoring tool that captures live public safety FM broadcasts, demodulates them, transcribes the audio using OpenAI Whisper, and summarizes activity with LLMs. It runs on commodity RTL-SDR hardware and serves results through a web-based dashboard for browsing and searching transcripts.
How It Works
A Python pipeline handles the full chain: RTL-SDR capture, FM demodulation, chunked audio recording, Whisper transcription, and LLM summarization. Transcripts are stored in SQLite with full-text search. The web UI — built with FastAPI — provides a real-time feed of activity and a searchable archive.
Built as a personal project at the intersection of amateur radio and AI tooling.
