Sdrangel
SDRangel is a comprehensive software-defined radio suite and digital signal processing framework. It functions as an RF spectrum analyzer and modular radio demodulator, providing a unified hardware abstraction layer to connect various radio devices to software processing pipelines for data acquisition and transmission.
The platform is distinguished by its modular architecture, which uses a data-flow graph of dynamic libraries to construct signal processing chains. This allows for a plugin-based environment where users can extract audio and digital data from raw radio signals using various modulation schemes.
The system covers a broad range of capabilities including radio frequency spectrum monitoring, satellite signal reception, and wireless signal transmission. It features modular plugin processing for signal demodulation, frequency tracking, and spectrum hotspot scanning, alongside tools for managing push-to-talk switching and headless hardware control via a web-based interface.
The software supports containerized deployment to simplify installation across different operating systems.
