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

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.

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.

This a C-language library for common DSP (Digital Signal Processing) primitives for SDR (Software Defined Radio).

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 is a generic data receiver, mainly for decoding radio transmissions from devices on the 433 MHz, 868 MHz, 315 MHz, 345 MHz and 915 MHz ISM bands.

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)

WSJT-X implements communication protocols or modes called FT4, FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon. These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.

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 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.

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

This package provides Cgo bindings to PulseAudio's Simple API, to play or capture raw audio.

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 HackRF devices support to the SoapySDR library.

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.

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

• Classic exercise,

• Koch method,

• Read from file,

• Callsign exercise.

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

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

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.

FLMSG is a Narrow Band Emergency Messaging Software (NBEMS). It can be used to manage, send and receive the forms that are used as basis for emergency communications data transfers (like ICS213 forms).

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

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.

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).

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