JS8Call is a software using the JS8 digital mode (a derivative of the FT8 mode) providing weak signal keyboard to keyboard messaging to amateur radio operators.

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

wfview is a program to control modern Icom radios and view the spectrum waterfall. It supports at least the following models:

• IC-705

• IC-905

• IC-7300

• IC-7610

• IC-7850

• IC-7851

• IC-9700

The soapy_power obtains the power spectrum from SDR devices that are supported by the SoapySDR library.

This is a Pulseaudio client library in Golang for creating virtual sinks and sources.

This package provides BladeRF devices support to the SoapySDR library.

This package provides support for sound card devices to the SoapySDR library. It also adds hamlib support, which provides basic gain and frequency controls for certain tuners which may be paired with an audio device.

Chirp is a cross-radio programming tool. It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them.

This package provides the driver and utilities for controlling the Airspy Software Defined Radio (SDR) over USB.

To install the airspy udev rules, you must extend udev-service-type with this package. E.g.: (udev-rules-service 'airspy airspy)

Aldo is a morse code learning tool providing four type of training methods:

• Classic exercise,

• Koch method,

• Read from file,

• Callsign exercise.

This package provides Airspy devices support to the SoapySDR library.

This package provides a GNU Radio block interfacing with Digital Speech Decoder (DSD) to decode several digital voice protocols, like D-STAR, DMR, NXDN, P25, etc.

This package provides a library and a program to decode several digital voice formats.

Minimodem is a command-line program which decodes (or generates) audio modem tones at any specified baud rate, using various framing protocols. It acts a general-purpose software FSK modem, and includes support for various standard FSK protocols such as Bell103, Bell202, RTTY, TTY/TDD, NOAA SAME, and Caller-ID.

This package provides the driver and utilities for controlling the Airspy HF+ Software Defined Radio (SDR) over USB.

To install the airspyhf udev rules, you must extend udev-service-type with this package. E.g.: (udev-rules-service 'airspyhf airspyhf)

WSJT-X implements communication protocols or modes called FT4, FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.

Xnec2c is a GTK3-based graphical version of nec2c, a translation to the C language of NEC2, the FORTRAN Numerical Electromagnetics Code commonly used for antenna simulation and analysis. It can be used to define the geometry of an antenna, and then plot the radiation pattern or frequency-related data like gain and standing wave ratio.

This package provides Cgo bindings to PulseAudio's Simple API, to play or capture raw audio.

This program contains algorithms to demodulate and decode AIS (Automatic Identification System) messages sent by ships and coast stations.

This package includes the libcsdr library of DSP functions for SDRs, and the csdr command line program that can be used to build simple signal processing flow graphs.

NanoVNA-Saver is a tool for reading, displaying and saving data from the NanoVNA vector network analyzers.

This program is a software-defined receiver which is able to process (that is, to perform detection, synchronization, demodulation and decoding of the navigation message, computation of observables and, finally, computation of position fixes) the signals of the BeiDou, Galileo, GLONASS and GPS Global Navigation Satellite System.

QSSTV is a program for receiving and transmitting SSTV and HAMDRM (sometimes called DSSTV). It is compatible with most of MMSSTV and EasyPal.

This is a GNU Radio block to correct IQ imbalance in quadrature receivers. It's composed of two main block:

• Fix: Given a phase and amplitude error, it will correct a complex signal.

• Optimize: Attempts to auto-detect the phase and amplitude error to feed to the fix block above.
