LISA is an acronym for "Lightweight Integrated System for Amateur Radio". It may also refer to the intelligent little girl from the Simpsons TV show - it's up to you. LISA provides a GUI framework for different modules related to amateur radio and linking them together in one integrated application environment.

All of this is based on the Qt libraries which ensure that LISA can be run on Windows, OSX and Linux.

The individual application functionality is provided through plugins, each of which focusses on a different task.

The following plugins are currently implemented and are worked upon:

• Core Provides core functionality for the main application.
• Logbook Provides an amateur radio logbook based on a SQLite database.
• Digital Provides all features to be used during digital operation such as encoding/decoding digital protocols like PSK31, RTTY, etc.

Lots of different plugins can be thought of. Some of them include:

• Control Provides the functionality to control various kinds of transceivers. Possible backends are hamlib and RigCAT.
• CloudStorage Provides the ability to save and load various kinds of data from various kinds of cloud storages (i.e. Google Drive, Dropbox, Owncloud etc...)
• CallsignLookup Provides an interface to query callsign information from various callsign databases like QRZ.com
• Rotator Connects to a rotator device and allows the user to rotate his beams from within the application. Can also be used to align the beams for satellite operation

The application is based on the QtCreator source code, since it already provides a working application environment with a plugin ecosystem. Building is done through the QMake build system alone. To start developing, use the QtCreator IDE for your operating system and open the .pro file. Building has mainly been tested under windows, although it should be possible to build unter Unix as well.

The application has been built on top of the QtCreator source code. Code that is based on QtCreator is licensed under LGPL 2.1. The LISA plugins themselves are licensed under GPL 3. Please respect the licensing at any time.

LISA uses information and knowledge from the following open source projects:

• fldigi
• GNURadio
• CuteSDR

Contributing to the application is highly welcomed. If you want to contribute, contact the author via GitHub or issue a pull request. However, please note that contributing is not wise in the current development stage, since lots of concepts will change until everything is stable.
