SigDigger is described as 'Qt5 digital signal analyzer written in C/C++ that runs in GNU/Linux, macOS and Windows. SigDigger uses its own DSP library (sigutils) and a realtime signal analysis library (Suscan) to distribute load, and supports most SDR devices in the market thanks to SoapySDR' and is an app. There are eight alternatives to SigDigger for a variety of platforms, including Linux, Windows, Mac, Flathub and Flatpak apps. The best SigDigger alternative is Gqrx, which is both free and Open Source. Other great apps like SigDigger are GNU Radio, SDR++, CubicSDR and SDR#.
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.
Gqrx is the most popular Mac & Linux alternative to SigDigger.
Gqrx is the most popular Open Source & free alternative to SigDigger.
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like...
GNU Radio is the most popular Windows alternative to SigDigger.
SDR++ is an open source, cross platform, C++ based GUI general receiver program for various SDRs including the RTL-SDR. Since it's alpha release in mid 2020, it has undergone huge amount of development, and is quickly becoming the main program of choice for many users due to...
CubicSDR is a cross-platform Software-Defined Radio application which allows you to navigate the radio spectrum and demodulate any signals you might discover.
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.
inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.
SDR Rx/Tx software for Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay RSP1 and FunCube
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.
