• IC-705

• IC-905

• IC-7300

• IC-7610

• IC-7850

• IC-7851

• IC-9700

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.

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 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).

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

This package provides HackRF devices support to the SoapySDR library.

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

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).

Flrig is a transceiver control program for amateur radio use. It provides computer aided control of various radios using a serial or USB connection.

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.

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

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).

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

Flwrap is a software utility for amateur radio use. Its purpose is to encapsulate both text and binary files in a way that allows them to be transmitted over any of several digital modes and verified at the receipt end for correctness.

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

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

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

• Classic exercise,

• Koch method,

• Read from file,

• Callsign exercise.

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.

This package provides a library for decoding the contents of ACARS messages used by planes.

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.

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