The Racket CS implementation, which uses ``Chez Scheme'' as its core compiler and runtime system, has been the default Racket VM implementation since Racket 8.0. It performs better than the Racket BC implementation for most programs. On systems for which Racket CS cannot generate machine code, this package uses a variant of its ``portable bytecode'' backend specialized for word size and endianness.

Using the Racket VM packages directly is not recommended: instead, install the racket-minimal or racket packages.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The ``minimal Racket'' distribution includes just enough of Racket for you to use raco pkg to install more. Bundled packages, such as the DrRacket IDE, are not included.

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.

Acarsdec is a multi-channels acars decoder with built-in rtl_sdr, airspy front end or sdrplay device. Since 3.0, it comes with acarsserv to store received acars messages.

This package provides BladeRF devices support to the SoapySDR library.

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

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

GNU Radio is a development toolkit that provides signal processing blocks to implement software radios. It can be used with external RF hardware to create software-defined radios, or without hardware in a simulation-like environment.

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

• Classic exercise,

• Koch method,

• Read from file,

• Callsign exercise.

Aptdec decodes Automatic Picture Transmission (APT) images. These are medium resolution images of the Earth transmitted by, among other satellites, the POES NOAA weather satellite series. These transmissions are on a frequency of 137 MHz. They can be received using an inexpensive antenna and a dedicated receiver.

This package provides RTL-SDR devices support to the SoapySDR library.

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)

This package provides Airspy HF+ devices support to the SoapySDR library.

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

Multimon-ng can decode several digital radio transmission modes:

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

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).

The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios.

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)

This is a SoapySDR module to use a supported device transparently over a local network link.

This package provides Airspy devices support to the SoapySDR library.

SerialDV is a minimal interface to encode and decode audio with AMBE3000 based devices in packet mode over a serial link.

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

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