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 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 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.

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

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

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.

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.

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.

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)
