What D-Star is about

D-STAR transfers both voice and data via digital encoding over the 2 m (VHF), 70 cm (UHF), and 23 cm (1.2 GHz) amateur radio bands. Voice is encoded as a 3600 bit/s data stream using proprietary AMBE encoding, with 1200 bit/s FEC, leaving 1200 bit/s for data encoding. On air bit rates are 4800 bit/s over the 2 m, 70 cm and 23 cm bands. Digital only data can be sent at 128 kbit/s only on the 23 cm band. Radios providing data service use a RS-232 or USB connection for low speed data (1200 bit/s) and Ethernet for high speed (128 kbit/s) connections to allow easy interfacing with computer equipment.
