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).

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.

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)

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.

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

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

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

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

Meshtastic Python is a small library which provides an easy API for sending and receiving messages over mesh radios. It provides access to any of the operations/data available in the device user interface or the Android applications. Events are delivered using a publish-subscribe model, and you can subscribe to only the message types you are interested in.

This is a library to decode DAB/DAB+.

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

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.

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.

KochMorse is a simple morse-code tutor using the Koch method.

This is a block for GNU Radio allowing to use a common API to access different radio hardware.

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

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

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)

unixcw is a project providing the libcw library and a set of programs using the library: cw, cwgen, cwcp and xcwcp. The programs are intended for people who want to learn receiving and sending morse code.

Libiio is used to interface to the Linux Industrial Input/Output (IIO) Subsystem. The Linux IIO subsystem is intended to provide support for devices that in some sense are analog to digital or digital to analog converters (ADCs, DACs). This includes, but is not limited to ADCs, Accelerometers, Gyros, IMUs, Capacitance to Digital Converters (CDCs), Pressure Sensors, Color, Light and Proximity Sensors, Temperature Sensors, Magnetometers, DACs, DDS (Direct Digital Synthesis), PLLs (Phase Locked Loops), Variable/Programmable Gain Amplifiers (VGA, PGA), and RF transceivers. You can use libiio natively on an embedded Linux target (local mode), or use libiio to communicate remotely to that same target from a host Linux, Windows or MAC over USB or Ethernet or Serial.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax.

ActiveSupport is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. It includes support for multibyte strings, internationalization, time zones, and testing.

railties provides the core Rails internals including handling application bootup, plugins, generators, and Rake tasks.

This Ruby library integrates SassC-Ruby into Rails.
