This library contains VOLK kernels of hand-written SIMD code for different mathematical operations used by GNSS-SDR, mainly with 8-bit and 16-bit real and complex data types, offering a platform/architecture agnostic version that will run in all machines, plus other versions for different SIMD instruction sets.

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

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

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).

Dire Wolf is a Terminal Node Controller (TNC) for Amateur Packet Radio. It can perform as:

• APRS GPS tracker,

• Digipeater,

• Internet gateway (IGate)

• APRStt gateway

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 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)

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

This package provides a frequency scanner for the Gqrx software-defined radio receiver.

This is a library to decode DAB/DAB+.

This package provides BladeRF devices support to the SoapySDR library.

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

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

rfcat is a program to control some radio dongles operating in ISM bands.

Supported dongles:

• YARD Stick One

• cc1111emk

• chronos watch dongle

• imme (limited support)

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

Dump1090 is a Mode S decoder specifically designed for rtl-sdr devices. It can be used to decode the ADS-B signals that planes emit to indicate their position, altitude, speed, etc.

redsea is a lightweight command-line FM Radio Data System (FM-RDS) decoder. Redsea can be used with any RTL-SDR USB radio stick with the rtl_fm tool, or any other software-defined radio (SDR) via csdr, for example. It can also decode raw ASCII bitstream, the hex format used by RDS Spy, and audio files containing multiplex signals (MPX).

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.

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

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

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

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 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.

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