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

Fldigi is a software modem for amateur radio use. It is a sound card based program that is used for both transmitting and receiving data by connecting the microphone and headphone connections of a computer to some radio hardware.

Liquid DSP is a digital signal processing (DSP) library designed specifically for software-defined radios on embedded platforms. The aim is to provide a lightweight DSP library that does not rely on a myriad of external dependencies or proprietary and otherwise cumbersome frameworks. All signal processing elements are designed to be flexible, scalable, and dynamic, including filters, filter design, oscillators, modems, synchronizers, complex mathematical operations, and much more.

This package provides the rx_fm, rx_power and rx_sdr tools for receiving data from SDRs, based on rtl_fm, rtl_power and rtl_sdr from RTL-SDR, but using the SoapySDR vendor-neutral SDR support library instead, intended to support a wider range of devices than RTL-SDR.

The Ham Radio Control Library (Hamlib) 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.

gr-satellites is a GNU Radio out-of-tree module encompassing a collection of telemetry decoders that supports many different Amateur satellites.

Gqrx is a software defined radio (SDR) receiver implemented using GNU Radio and the Qt GUI toolkit.

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.

SatDump is a generic satellite data processing software. For example, it can decode the telemetry and images sent by some meteorological satellites.

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

JTDX means "JT,T10 and FT8 and FT4 modes for DXing", it is being developed with main focus on the sensitivity and decoding efficiency, both, in overcrowded and half empty HF band conditions.

It is modified WSJT-X software forked from WSJT-X r6462. JTDX supports JT9, JT65, T10, FT8 and FT4 © digital modes for HF amateur radio communication, focused on DXing and being shaped by community of DXers.JTDX

The Ham Radio Control Library (Hamlib) 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.

Flwrap is a software utility for amateur radio use. Its purpose is to encapsulate both text and binary files in a way that allows them to be transmitted over any of several digital modes and verified at the receipt end for correctness.

SDR++ is a software defined radio software for various hardware.

This package provides a spectrum analyzer for multiple SDR platforms. It is a GUI for soapy_power, hackrf_sweep, rtl_power, rx_power and other backends.

This package provides a set of functions that implement several popular forward error correction (FEC) algorithms and several low-level routines useful in modems implemented with digital signal processing (DSP).

Lime Suite NG is a collection of software supporting several hardware platforms based on the LMS7002M transceiver under the LimeSDR name. It provides a C++ API, command-line tools, a GUI, and plugins for multiple SDR tools.

Command line utilities and a C library for controlling the HackRF Software Defined Radio (SDR) over USB. Installing this package installs the userspace hackrf utilities and C library. To install the hackrf udev rules, you must extend 'udev-service-type' with this package. E.g.: (udev-rules-service 'hackrf hackrf #:groups '("dialout")).

This package provides a decoder for VDL Mode 2 messages used by planes.

This package provides HackRF devices support to the SoapySDR library.

This is a SoapySDR module to use multiple supported devices under a single device wrapper.

welle.io is a Digital Audio Broadcasting (DAB and DAB+) software defined radio with support for rtl-sdr.

DVB-T dongles based on the Realtek RTL2832U can be used as a cheap software defined radio, since the chip allows transferring the raw I/Q samples to the host. rtl-sdr provides drivers for this purpose.

The default Linux driver managing DVB-T dongles as TV devices doesn't work for SDR purposes and clashes with this package. Therefore you must prevent the kernel from loading it automatically by adding the following line to your system configuration:

(kernel-arguments '("modprobe.blacklist=dvb_usb_rtl28xxu"))

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