CubicSDR is a cross-platform Software-Defined Radio application which allows you to navigate the radio spectrum and demodulate any signals you might discover. It currently includes several common analog demodulation schemes such as AM and FM and will support digital modes in the future. Many digital decoding applications are available now that can use the analog outputs to process digital signals by “piping” the data from CubicSDR to another program using software like Soundflower, Jack Audio
The Ham Radio Control Library–Hamlib, for short–is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users.
Mumble was the first VoIP application to establish true low latency voice communication over a decade ago. But low latency and gaming are not the only use cases it shines in. We heard from users who record podcasts with our multi-channel audio recorder, players seeking realism with our positional audio in games, Eve Online players with huge communities of over 100 simultaneous voice participants (I bet they make good use of our extensive permission system 😄), the competitive Team Fortress 2 com
Gqrx is an open source software defined radio receiver (SDR) powered by the GNU Radio and the Qt graphical toolkit. Gqrx supports many of the SDR hardware available, including Airspy, Funcube Dongles, rtl-sdr, HackRF and USRP devices. See supported devices for a complete list. Discover devices attached to the computer. Process I/Q data from the supported devices. Change frequency, gain and apply various corrections (frequency, I/Q balance). AM, SSB, CW, FM-N and FM-W (mono and
QRadioLink is a Linux software defined radio transceiver application using VOIP for inter-communication, built on top of GNU radio, which allows experimenting with software defined radio hardware using different digital and analog radio signals and a friendly user interface. Its primary purpose is educational, but it can also be customized for low power data communications on various frequency bands. It can also be used as an amateur radio SDR transceiver for demonstrating radio communications
The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios. URH allows easy demodulation of signals combined with an automatic detection of modulation parameters making it a breeze to identify the bits and bytes that fly over the air. As data often gets encoded before transmission, URH offers customizable decodings to crack even sophisticated encodings like CC1101 data whitening. When it comes to protocol r
GNU Radio is a free software development toolkit that provides signal processing blocks to implement software-defined radios and signal-processing systems. It can be used with external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems.
SDR++ is a cross-platform and open source SDR software with the aim of being bloat-free and simple to use. Features Multi VFO Wide hardware support (both through SoapySDR and dedicated modules) SIMD accelerated DSP Cross-platform (Windows, Linux, MacOS and BSD) Full waterfall update when possible. Makes browsing signals easier and more pleasant Modular design (easily write your own plugins)
Trusted QSL keeps eQSL an open and free activity for amateur radio operators. It promotes the Digital Signature Standard (DSS).
Shortwave is an internet radio player that provides access to a station database with over 30,000 stations. It is the successor to gradio http://freshcode.club/gradio
SigDigger is a Qt5 digital signal analyzer written in C/C++ that runs in GNU/Linux, macOS and Windows. Unlike existing alternatives, SigDigger is not based on GNU Radio. Instead, it uses its own DSP library (sigutils) and a realtime signal analysis library (Suscan) that exploits multicore CPUs to distribute load. Also, SigDigger supports most SDR devices in the market thanks to SoapySDR. Sigutils, Suscan and SigDigger are software libre, licensed under the terms of the General Public License ver
Fldigi is a digital modem application for common amateur radio systems. It supports CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb. It also helps calibrating a sound card to a time signal and perform frequency measurement tests. Flmsg is a messaging tool over digital radio, while Flarq supports ARQ file transfers.
Tomahawk is a music player and audio streaming service frontend for desktop usage. It manages songs, albums, playlists, meta info, social sharing. It supports various cloud services and commercial providers, such as Spotify, Beats, Google play, Soundcloud, LastFM, Hype Machine, Echo Nest, Rdio, Grooveshark, Billboard, OwnCloud, iTunes, Jamendo, Deezer, Ampache, Jabber, and Subsonic.
The WSJT project ("Weak Signal Communication, by K1JT") provides five programs (WSJT, WSJT-X, MAP65, WSPR, SimJT) designed for amateur radio communication. They include applications for meteor scatter, ionospheric scatter, EME ("moonbounce"), and QRP communication at HF.
