HDSDR is not available for Linux but there are some alternatives that runs on Linux with similar functionality. The best Linux alternative is Gqrx, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 10 alternatives to HDSDR and nine of them are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to HDSDR are SDRangel, GNU Radio, CubicSDR and SDR++.


SDR Rx/Tx software for Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay RSP1 and FunCube

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...

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...

inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.




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.


QRadioLink is a multimode SDR transceiver application using VOIP communication (radio over IP), built on top of GNU radio, which allows experimenting with software defined radio hardware using different digital and analog radio signals and a Qt5 UI.




SDRAngel is the most complete and signal-processing-correct SDR digital processor I have found for running the LimeUSB SDR boards.
