D-STAR (Digital Smart Technologies for Amateur Radio).

D-STAR is an up and coming digital voice and data protocol specification, first published in 2001, developed for use in amateur radio available on VHF and UHF amateur radio bands.

In addition to the over-the-air protocol, D-Star also provides specifications for network connectivity, enabling D-Star radios to be connected to the Internet or other networks.

D-STAR is the result of research by the Japan Amateur Radio League (JARL) to investigate digital technologies for amateur radio. To date only ICOM produce amateur radio equipment including the D-Star technology.

D-STAR repeaters act just like familiar analog repeaters: everyone listening can hear your transmissions. Your call sign is incorporated into every transmission. The D-STAR repeater 'registers' your call sign and shares it around the D-STAR system.

Now for the really clever bit! If you move into a new D-STAR repeater’s coverage area and register with a short transmission, your location will be quickly updated around the D-STAR network. This allows you to call someone registered with any other D-STAR repeater, no matter where that may be. If you call someone registered elsewhere, your voice will be routed to the appropriate repeater in digital form, where it is then heard just as you would expect if you were both using the same repeater.

D-Star can, of course, be used simplex as well. To this end there are 3 D-STAR simplex calling frequencies:
