In 2001, the Japan Amateur Radio League (JARL) published the concept for D-STAR (Digital Smart Technologies for Amateur Radio), a digital communication protocol designed to enhance amateur radio operations. D-STAR facilitates efficient and flexible communication by using digital voice and data capabilities. This protocol supports advanced features such as digital voice, low-speed data, and high-speed data transmission, allowing for clear, reliable communication and innovative applications like GPS tracking and internet connectivity. The introduction of D-STAR marked a significant advancement in amateur radio technology, encouraging the adoption of digital modes and expanding the capabilities and versatility of amateur radio communication worldwide.
