D-Star Information

D-STAR (Digital Smart Technologies for Amateur Radio) is a digital voice and data protocol specification for amateur radio, developed in the late 1990s by the Japan Amateur Radio League, and popularized by the Japanese amateur radio manufacturer Icom.

D-STAR is an open standard, available to be implemented by any person or vendor. However, it uses the closed-source proprietary AMBE voice codec, patented by Digital Voice Systems, Inc.

TCARA operates a 70cm D-STAR repeater at 449.025 MHz on Reflector: XRF980A
