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).

FLAMP is a program for transferring files by radio waves using AMP (Amateur Multicast Protocol).

This package provides HackRF devices support to the SoapySDR library.

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.

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

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

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.
