NQC

NQC is a free and open-source software package for controlling amateur radio equipment. It was first released in 2006 and has since become one of the most popular client-server control systems used by amateur radio operators.

NQC is designed to work with the Win4Icom interface software, which allows users to use their personal computers as a controller for their amateur radio equipment. The software is capable of controlling various aspects of the radio equipment, including frequency, mode, and volume.

One of the key features of NQC is its ability to connect to multiple servers, allowing users to take control of multiple radio stations from a single location. This can be useful for club meetings, contests, and other events where multiple operators need to be in control of their equipment at once.

NQC is also highly customizable, allowing users to create their own scripts and macros to automate various tasks. This can range from simple tasks such as transmitting a greeting to more complex operations such as automatically switching to a specific frequency.

In addition to its control features, NQC also includes a chat function that allows users to communicate with each other in real-time. This can be useful for coordinating activities with other operators and staying up to date on any issues that may arise.

NQC is developed by a team of volunteers and is released under the GPL license. It is available for download from the official website and can be used with a wide range of amateur radio equipment.
