GNU Radio is described as 'free & open-source software development toolkit that provides signal processing blocks to implement software radios'. There are more than 10 alternatives to GNU Radio for Linux, Mac, Windows, Android and BSD. The best alternative is CubicSDR, which is both free and Open Source. Other great apps like GNU Radio are SDR# (Free), Gqrx (Free, Open Source), Universal Radio Hacker (Free, Open Source) and Simulink (Paid).
SDR# (SDRSharp) is a popular, simple, fast and extensible Software Defined Radio program written from scratch in C# to experiment new Digital Signal Processing techniques and push the Microsoft .NET Framework to its limits.
Gqrx is a software defined radio receiver powered by the GNU Radio SDR framework and the Qt graphical toolkit. It supports many of the SDR hardware available, including Funcube Dongles, rtl-sdr, HackRF and USRP devices.
urh - Universal Radio Hacker: investigate wireless protocols like a boss Features include: - hardware interfaces for common Software Defined Radios - easy demodulation of signals - assigning participants to keep overview of your data - customizable decodings to crack even...
Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail.
HDSDR is a freeware Software Defined Radio (SDR) program for Microsoft Windows 2000/XP/Vista/7/8/8.1/10. Typical applications are Radio listening, Ham Radio, SWL, Radio Astronomy, NDB-hunting and Spectrum analysis.
A graphical application for showing the Fast Fourier Transformation (FFT) as graph and waterfall diagram of the radio spectrum retrieved by Software Defined Radio (SDR) devices supported by GrOsmoSDR. Plugins enable demodulating a selected signal.
SoapySDR is an open-source generalized C/C++ API and runtime library for interfacing with SDR devices. With SoapySDR, you can instantiate, configure, and stream with an SDR device in a variety of environments. Both osmosdr and uhd devices are available within SoapySDR.
