AetherSDR is an open-source amateur radio workstation for controlling FlexRadio FLEX-6000, FLEX-8000, and Aurora transceivers. Built with Qt6 and C++20, it runs natively on Windows, macOS, Linux, and compatible ARM devices. GPU-accelerated spectrum displays and waterfalls provide real-time signal visualization. Multiple receivers and panadapters support independent tuning and transmission controls. Integrated audio processing offers equalization, compression, noise reduction, and voice enhancement. Digital communication tools support DAX audio, IQ streams, packet radio, and Morse code operation. Additional capabilities include remote radio access, public SDR receiver browsing, spotting networks, and propagation maps. Its modular interface supports advanced amateur radio workflows.
