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.

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.

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

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

This package provides BladeRF devices support to the SoapySDR library.

This package provide a simple pythonic wrapper for the SoapySDR library.

This package contains a library and command line utilities for controlling the BladeRF Software Defined Radio (SDR) over USB. To install the bladerf udev rules, you must extend 'udev-service-type' with this package. E.g.: (udev-rules-service 'bladerf bladerf).

SDRangel is a Qt software defined radio and signal analyzer frontend for various hardware.

qdmr is a graphical user interface (GUI) application that allows one to program several types of DMR radios. It is comparable to the Customer Programming Software (CPS) bundled with these radios but aims to be a more universal tool.

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

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)

SoapySDR is a library designed to support several kinds of software defined radio hardware devices with a common API.

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

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.

This is a C++ library implementing fast GF(256) Cauchy MDS Block Erasure Codec.

Multimon-ng can decode several digital radio transmission modes:

• POCSAG512, POCSAG1200, POCSAG2400

• FLEX

• EAS

• UFSK1200, CLIPFSK, AFSK1200, AFSK2400, AFSK2400_2, AFSK2400_3

• HAPN4800

• FSK9600

• DTMF

• ZVEI1, ZVEI2, ZVEI3, DZVEI, PZVEI

• EEA, EIA, CCIR

• MORSE CW

• X10

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")).

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.

This library provides convolutional and Reed-Solomon codes for forward error correction. It also includes a compatibility layer so that it can be used as a drop-in substitute for libfec.

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.

This package provides a library for decoding the contents of ACARS messages used by planes.

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

This package provides Airspy devices support to the SoapySDR library.

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)
