Gqrx is a software defined radio application used to capture and demodulate radio signals across various frequencies to produce audio and visual data. It translates raw radio waves into audible sound using standard modes including AM, FM, SSB, and CW.
The project provides tools for radio signal analysis through real-time frequency plots and waterfall displays. It enables the capture of raw baseband data and received audio for offline playback and technical analysis.
The software includes capabilities for tuning radio frequencies, filtering signal noise via band-pass filters and gain control, and managing hardware configurations through portable session files. It also supports remote receiver control via network sockets and audio streaming over UDP.
