History

D-STAR (Digital Smart Technologies for Amateur Radio) is a digital voice and data mode for amateur radio that was developed by the Japan Amateur Radio League in 2001.

This mode supports digital voice, low speed text message data, and GPS positioning data all simulatneously on one VHF or UHF frequency.

D-STAR Repeater sites can be linked via the Internet to a global network. Radios can be followed by callsign as it is handed off from one networked repeater to another.

At 1.2 gHz and 10 gHz higher data rates sufficent to support TCP/IP traffic and peer to peer networking are supported.

To date ICOM is the only manufacturer of amateur radio equipment to produce an entire line of D-STAR equipment.

In recent years, amateurs around the world have been experimenting with home made equipment and software designs to support D-STAR and other digital voice and data modes.

Saskatoon D-STAR is such a group, experimenting with both ICOM and home made equipment to further explore the potential of narrow band digital communications modes.

The founding members of this group are VA5LF, VE5DWR and VE5PNQ.

This web site will be used to discuss issues related to building DStar repeaters, interfacing radios and software developments.
