Gqrx is a software defined radio receiver (SDR) powered by the GNU Radio and the Qt graphical toolkit.
Currently it works on Linux and Mac with hardware supported by gr-osmosdr, including Funcube Dongle, RTL-SDR, Airspy, HackRF, BladeRF, RFSpace, USRP and SoapySDR.
Gqrx can operate as an AM/FM/SSB receiver with audio output or as an FFT-only instrument. There are also various hooks for interacting with external applications using network sockets.
This is free and open source software.
