What is D-Star?

Most amateur radio voice chat is analogue. D-Star is one of the relatively new Digital Voice (DV) modes.

D-Star is championed by manufacturer Icom. Other DV formats include DMR (Motorola and others) and Fusion (Yaesu)

D-Star offers some strong advantages over analogue voice:

  • Connectivity around the world using the Internet
  • Can be used to GPS positioning information
  • Automatic logging of callsigns, plus online logs of traffic
  • Digital audio quality
  • Option to set your radio to “Call Squelch”, so you will only receive calls for you.
  • Reflectors (Regional ‘chatrooms’)


Using D-Star

You’ll need a D-Star radio – they’re made by Icom, and they’re not cheap –  Prices for a typical D-Star handheld are around £300.

Setting up a D-Star radio can be tricky, as you are required to program extra settings for each repeater, and also set the radio to transmit your callsign in text format.

One of the benefits of D-Star, is that you can link your radio and your repeater to others over the Internet. You could be driving around Chelmsford, connected to the Danbury D-Star repeater, talking to someone driving around New York. Before you can use the Internet connectivity, you have to be registered on the D-Star network (See D-Star Registration in Essex)
