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.

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

This is a library to decode DAB/DAB+.

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

convert-samples is a command-line program to convert samples received from software defined radios from one format to another.

Supported formats:

• s8: signed 8 bit integer

• u8: unsigned 8 bit integer

• s16: signed 16 bit integer

• u16: unsigned 16 bit integer

• s32: signed 32 bit integer

• u32: unsigned 32 bit integer

• f32: 32 bit float

• cs8: complex made of signed 8 bit integers

• cu8: complex made of unsigned 8 bit integers

• cs16: complex made of signed 16 bit integers

• cu16: complex made of unsigned 16 bit integers

• cs32: complex made of signed 32 bit integers

• cu32: complex made of unsigned 32 bit integers

• cf32: complex made of 32 bit floats

Dire Wolf is a Terminal Node Controller (TNC) for Amateur Packet Radio. It can perform as:

• APRS GPS tracker,

• Digipeater,

• Internet gateway (IGate)

• APRStt gateway

This program is a software-defined receiver which is able to process (that is, to perform detection, synchronization, demodulation and decoding of the navigation message, computation of observables and, finally, computation of position fixes) the signals of the BeiDou, Galileo, GLONASS and GPS Global Navigation Satellite System.

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

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 package provides RTL-SDR devices support to the SoapySDR library.

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

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.

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.

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

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

This gem provides Ruby and Ruby on Rails integration with Autoprefixer, which can parse CSS and add vendor prefixes to CSS rules using values from the Can I Use website.

This package allows you to create an interactive Ruby session in your browser. Those sessions are launched automatically in case of an error and can also be launched manually in any page.

This package provides support for using RSpec to test Ruby on Rails applications, in pace of the default Minitest testing library.

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.

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

Turbo aims to be as fast as single-page web application without having to write any JavaScript. Turbo accelerates links and form submissions without requiring server-side changes to the generated HTML. It allows carving up a page into independent frames, which can be lazy-loaded and operated as independent components. Finally, it helps making partial page updates using just HTML and a set of CRUD-like container tags. These three techniques reduce the amount of custom JavaScript that many web applications need to write by an order of magnitude. And for the few dynamic bits that are left, Stimulus can be used.

Bootsnap is a library that plugs into Ruby, with optional support for YAML, to optimize and cache expensive computations.

The ammeter gem makes it easy to write specs for Rails generators. An existing user is rspec-rails, which uses ammeter to spec its own generators.

ActionView provides conventions and helpers for building web pages in Ruby.
