subghz-sdr

What problem does it solve?

An SDR-driven framework for sub-GHz RF signal analysis that enables capture, demodulation, replay, and fuzz testing of <1GHz protocols to uncover vulnerabilities and understand RF communications in lab environments.

Core Features & Use Cases

• Spectrum analysis and signal identification across common sub-GHz bands (e.g., 315, 433.92, 868, 915 MHz)
• Capture, recording, and replay of RF signals using SDR hardware (HackRF, RTL-SDR, Flipper Zero)
• Protocol reverse engineering, demodulation, and decoding of observed transmissions
• Jamming and interference testing within safe, legal, and regulatory guidelines
• Custom signal generation and transmission for testing and validation
• Documentation of findings, including frequency, modulation, timing, and protocol notes
• Use Case: Investigate garage remotes, IoT RF devices, and other sub-GHz systems in CTF or security assessment contexts.

Quick Start

Start a new SDR analysis session with your HackRF or RTL-SDR and begin a basic capture and demodulation workflow on a target sub-GHz signal.
