Hamlib is an open-source software library that provides a standardized interface for controlling amateur radio equipment. It allows developers to write applications that can communicate with and control a wide range of radio transceivers and receivers, supporting various models and manufacturers. Hamlib facilitates the development of radio control software, enabling seamless integration with different radio hardware through a common API (Application Programming Interface).
Hamlib is developed by a community of volunteers and contributors in the amateur radio community. It is an open-source project, which means that the source code is freely available, and users are typically free to modify, distribute, and use the software within the terms of its open-source license. The collaborative nature of open-source projects allows individuals from around the world to contribute to the development and improvement of hamlib.
