JS8Call is a software using the JS8 digital mode (a derivative of the FT8 mode) providing weak signal keyboard to keyboard messaging to amateur radio operators.

This package provides BladeRF devices support to the SoapySDR library.

This package provides a GNU Radio block interfacing with Digital Speech Decoder (DSD) to decode several digital voice protocols, like D-STAR, DMR, NXDN, P25, etc.

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

Inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

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

The Ham Radio Control Library (Hamlib) is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users.

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

GGMorse is a library that decodes Morse code in real-time from raw audio.

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.

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.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax.

Action Cable integrates WebSockets with Rails applications. Through WebSockets it allows for real-time features in web applications.

ActiveStorage integrates file storage services with Rails applications, allowing files to be attached to ActiveRecord models.

This library integrates the SASS stylesheet language into Ruby on Rails.

The With advisory lock gem adds advisory locking to ActiveRecord for PostgreSQL and MySQL. SQLite is also supported, but this uses the file system for locks.

Provides Sprockets implementation for the Rails Asset Pipeline.

Active Record connects classes to relational database table to establish an almost zero-configuration persistence layer for applications.

Spring is a Ruby on Rails application preloader. It speeds up development by keeping your application running in the background so the application does need to boot it every time you run a test, rake task or migration.

This Ruby library integrates SassC-Ruby into Rails.

This package provides a modest JavaScript framework for the HTML you already have.

Import maps can import JavaScript modules using logical names that map to versioned/digested files -- directly from the browser. It makes it possible to build modern JavaScript applications using JavaScript libraries made for ES modules (ESM) without the need for transpiling or bundling, which removes the need for Webpack, Yarn, npm, or any other part of the JavaScript toolchain. All that is needed is the asset pipeline that is already included in Rails.

ActionMailbox receives and processes incoming emails in Rails applications.

railties provides the core Rails internals including handling application bootup, plugins, generators, and Rake tasks.
