This package provides the rx_fm, rx_power and rx_sdr tools for receiving data from SDRs, based on rtl_fm, rtl_power and rtl_sdr from RTL-SDR, but using the SoapySDR vendor-neutral SDR support library instead, intended to support a wider range of devices than RTL-SDR.

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.

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).

radio_tool is a utility for reading, writing, and manipulating firmware/codeplugs on the following radios: TYT MD-2017, TYT MD-9600, TYT MD-UV380, TYT MD-UV390, TYT MD-390, TYT MD-380, TYT MD-446, TYT MD-280, Baofeng DM-1701, Baofeng DM1801, Baofeng RD-5R, Connect Systems CS800D, Ailunce HD1, Yaesu FT-70DR, and the Radioddity GD-77.

Lime Suite NG is a collection of software supporting several hardware platforms based on the LMS7002M transceiver under the LimeSDR name. It provides a C++ API, command-line tools, a GUI, and plugins for multiple SDR tools.

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

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.

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.

Gqrx is a software defined radio (SDR) receiver implemented using GNU Radio and the Qt GUI toolkit.

This package provides HackRF devices support to the SoapySDR library.

TLF is a Text User Interface amateur radio contest logging program. It integrates with radios supported by hamlib and other ham radio programs like fldigi. Many contests are supported including:

• CQWW (SO, M/S and M/M)

• WPX (SO, M/S and M/M)

• ARRL Sweepstakes (SO, M/S )

• EU SPRINT

• EUHFC

• ARRL-DX (both sides)

• ARRL-FD

• ARRL 10m

• ARRL 160m

• Region1 field day

• SP DX contest

• PACC (both sides)

• NRAU - scandinavian

• Wysiwyg mults mode (per band or per contest)

• WAEDX

It also supports connecting to DX clusters, log synchronization with other TLF instances over the network, and general QSO and DXpedition logging.

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

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).

DSD is able to decode several digital voice formats used in radio transmissions.

Kappanhang remotely opens audio channels and a serial port to an Icom RS-BA1 server. The application is mainly developed for connecting to the Icom IC-705 transceiver, which has built-in WiFi and RS-BA1 server.

Compatible hardware/software:

• Icom RS-BA1 server software,

• Icom IC-705

• Icom IC-9700

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

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

Dream is a software implementation of a Digital Radio Mondiale (DRM) receiver.

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

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.
