D-STAR (Digital Smart Technologies for Amateur Radio) is a digital voice and data protocol specification developed as the result of research by the Japan Amateur Radio League to investigate digital technologies for amateur radio. While there are other digital on-air technologies being used by amateurs that have come from other services, D-Star is one of the first on-air and packet-based standards to be widely deployed and sold by a major radio manufacturer that is designed specifically for amateur service use.


A multi-platform integrated tool for communication using D-STAR radios. With only a pair of radios (or an entire repeater stack) a variety of data transmission methods are supported, including:

  • Instant-message chat
  • Automatic beacon messages
  • File transfers with error detection
  • Structured forms
  • GPS position reports
  • Callsign matching and tracking for “last seen” reporting
  • Error-free file transfers with a single sender and multiple receivers
  • Multi-tab filtering and logging of traffic
  • Integrated offline station mapping support with freely-available map data
  • Network linking capability for bridging RF segments with a conventional network
  • Runs natively on Linux, Windows, and MacOSX
  • Freely-available, Open-source and GPL’d
