Quil is the quantum instruction language, originally developed at Rigetti Computing. In Quil quantum algorithms are expressed using Quil's standard gates and instructions

This package provides the asynchronous RPC client-server framework and message specification for Rigetti Quantum Cloud Services (QCS). It implements an efficient transport protocol by using ZeroMQ (ZMQ) sockets and MessagePack (msgpack) serialization.

This is the official Quil-Lang Quantum Virtual Machine (QVM), a flexible and efficient simulator for Quil.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The ``minimal Racket'' distribution includes just enough of Racket for you to use raco pkg to install more. Bundled packages, such as the DrRacket IDE, are not included.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The main Racket distribution comes with many bundled packages, including the DrRacket IDE, libraries for GUI and web programming, and implementations of languages such as Typed Racket, R5RS and R6RS Scheme, Algol 60, and Datalog.

Zuo is a tiny Racket with primitives for dealing with files and running processes. It comes with a make-like embedded DSL, which is used to build Racket itself.

Zuo is a Racket variant in the sense that program files start with #lang, and the module path after #lang determines the parsing and expansion of the file content. That's how the make-like DSL is defined, and even the base Zuo language is defined by layers of #langs. One of the early layers implements macros.

The Racket BC (``before Chez'' or ``bytecode'') implementation was the default before Racket 8.0. It uses a compiler written in C targeting architecture-independent bytecode, plus a JIT compiler on most platforms. Racket BC has a different C API than the current default runtime system, Racket CS (based on ``Chez Scheme'').

This package is the normal implementation of Racket BC with a precise garbage collector, 3M (``Moving Memory Manager'').

This variant of the Racket BC (``before Chez'' or ``bytecode'') implementation is not recommended for general use. It uses CGC (a ``Conservative Garbage Collector''), which was succeeded as default in PLT Scheme version 370 (which translates to 3.7 in the current versioning scheme) by the 3M variant, which in turn was succeeded in version 8.0 by the Racket CS implementation.

Racket CGC is primarily used for bootstrapping Racket BC [3M]. It may also be used for embedding applications without the annotations needed in C code to use the 3M garbage collector.

The Racket CS implementation, which uses ``Chez Scheme'' as its core compiler and runtime system, has been the default Racket VM implementation since Racket 8.0. It performs better than the Racket BC implementation for most programs. On systems for which Racket CS cannot generate machine code, this package uses a variant of its ``portable bytecode'' backend specialized for word size and endianness.

Using the Racket VM packages directly is not recommended: instead, install the racket-minimal or racket packages.

This is a SoapySDR module to use a supported device transparently over a local network link.

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

This package provides a spectrum analyzer for multiple SDR platforms. It is a GUI for soapy_power, hackrf_sweep, rtl_power, rx_power and other backends.

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

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

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.

Xnec2c is a GTK3-based graphical version of nec2c, a translation to the C language of NEC2, the FORTRAN Numerical Electromagnetics Code commonly used for antenna simulation and analysis. It can be used to define the geometry of an antenna, and then plot the radiation pattern or frequency-related data like gain and standing wave ratio.

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

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

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

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

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 BladeRF devices support to the SoapySDR library.

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