The term "D-Star" refers to a digital voice and data protocol specifically designed for amateur radio communication. It stands for "Digital Smart Technologies for Amateur Radio" and enables users to transmit both voice and data using digital techniques. D-Star allows for high-quality audio communication and supports the transmission of text data, GPS information, and other digital data formats.

This digital protocol operates over amateur radio frequencies and utilizes digital modulation methods, making it more efficient and versatile compared to traditional analog systems. D-Star's ability to facilitate both voice and data communication in a single mode contributes to its popularity among amateur radio operators, particularly for those seeking to integrate modern digital technology into their communications.

The other choices do not accurately describe D-Star. It is not limited to antenna types, methods of analog transmission, or merely a modulation technique. Instead, it encompasses a broader system that includes digital voice and data capabilities, making it a key tool in modern amateur radio practices.
