About:
Gqrx is a functional software-defined radio (SDR) receiver that leverages the power of GNU Radio and the Qt framework.

Real-time spectrum analysis and waterfall display
Decodes various modulation types including AM, FM, and LSB/USB
Cross-platform availability (Linux, macOS, Windows)

Use Cases:

Exploring and monitoring radio frequency spectrum
Listening to amateur radio, air traffic, or weather broadcasts
Signal analysis and educational purposes for radio enthusiasts
