What is D-Star?

D-STAR is a new amateur radio system which offers digital voice and data communication.

It connects repeater sites to the Internet and forms a wide area amateur radio network.

 The D-Star system provides a new capability and functionality to amateur radio.

What Does D-Star Provide?

Voice and data can reach further than ever
Multiple repeater links by radio and the Internet provide long distance communication to virtually anywhere.

The D-Star system will be upgraded
The D-Star system will be enhanced and new D-Star radios will be released, adding features and performance to the D-Star system.

128kbps digital data and 4.8kbps digital voice communication
The D-STAR system provides not only digital voice (DV mode) communication but also digital data transmission (DD mode).

 It can exchange various data files such as graphics, images, etc, at 128kbps.

 

Independent network
In DD mode, the Icom ID-1 radio can transfer data directly with another ID-1 without the use of a repeater.

 This is useful for establishing a simple network where a D-Star repeater does not exist or D-Star services are not required.

ON0DP  D-Star System

The complete D-Star repeater system is typically composed of a repeater controller, 23cm,70cm and 2mtr digital voice repeater,

23cm digital data repeater, and the Internet gateway computer.

ON0DP used a 23 cm and a 70cm voice module.

 For the signal is digital data, no information is lost due to conversion and multiple repeater relays are possible in this system.

The D-STAR system repeater can perform 2 relay functions as shown in the following figures.

 

1) Single repeater
The D-Star repeater operates similar to existing analog repeater.

That is a simple relay of transmit and receive communication.

 

2) Internet gateway relay
When D-Star repeaters are connected with the Internet gateway, the D-Star system relays the received data over the Internet.

  Internet gateways can be combined even during one contact. So your message will get through virtually to anywhere in the D-Star system.

Getting started:

Digital D-STAR technology opens up a vast new field for amateur radio.

This is an introduction to D-STAR local repeater use, cross banding and Internet link operations.

Using and Linking of D-Star repeaters is different to what is preformed on conventional FM, IRLP or internet EchoLink repeater operations.

 There are two methods used for digital repeater linking with D-STAR, they are User Linking and Port Linking.

           

YOUR or UR: The person or repeater port call sign you want to call.
 R1: The call sign and port of the repeater that you are talking on.
 R2: The call sign of the repeater that you are talking on, plus port designator you want to cross link to or gateway designator.
 MY: Your personal call sign

Example 1: Local conversation

Peter, ON4AAA calls Tom, ON5BBB on the local D-STAR 70cm repeater.

Peter configures his radio as follows:

     YOUR : CQCQCQ
R1 : ON0DP  B
  R2 : NOT USE*
MY : ON4AAA

 

Tom calls Peter stating that he is on repeater port B.

 The Digital Voice, DV data is only repeated on the local 70cm port B repeater.

Tom hears Peter calling him on the local repeater port B.

Tom configures his D-Star radio as follows:

  MYCALL : ON5BBB
        YOUR CALL : CQCQCQ
  RPT 1 B : ON0DP  B

                    RPT 2 B : NOT USE*                  

Peter returns the call and they have a local DV conversation.

Example 2: User Linking over the Internet

Actual configuration of two Belgian D-STAR repeaters

Peter, ON4AAA in Antwerp wants to call Bart ON7CCC on Digital D-STAR repeater in Oostende.

 ON4AAA is on 70cm repeater in Boom.

 The 70cm repeater is called ? repeater port B?.

 ON4AAA does not know nor does he need to know where Bart, ON7CCC is located.

This is called User Linking. 

Peter configures his radio as follows:

    YOUR : ON7CCC
 R1 : ON0DP  B
 R2 : ON0OS  G
MY : ON4AAA

 

Peter calls Bart. The DV data mode finds Bart in the repeater system.

Bart has recently talked on Oostende repeater port B and hears Peter calling.  

Bart configures his radio as follows:

  MYCALL : ON7CCC
UrCALL : ON4AAA
  RPT 1 B : ON0OS  B
   RPT 2 B : ON0OS  G

Bart returns the call to Peter and they have an Internet linked DV conversation.

·         Important Note: The port designator must always be in the 8th position.

 

Example 3: Port Linking over the Internet


Important Note:

For port linking to work correctly,

 please take note of the / (forward slash) in this section against the YOUR, UrCALL

or Your setting on your radio, for a correctly formatted port linking over the internet to work,

you must include the / preceding the repeater call sign you are calling,

also note that the repeater port being called is also in position 8 in the call sign format

 being called. i.e. /ON0OS  B

 

Tom, ON5BBB in Antwerp wants to call anyone on 2 meters in Oostende.

Tom is on the 70cm repeater of Boom.

The 2 meter repeater is called ? repeater port C?.

 This is called Port Linking.

Peter configures his  radio as follows :

   MYCALL : ON5BBB
          YOURCALL :  /ON0OS  C
  RPT 1 B : ON0DP  B
  RPT 2 B : ON0DP G

 

 Tom makes a general call, stating that he is on the ON0OS repeater port C.

The DV data mode from Tom is heard on the Oostende repeater system, port C and the repeater Boom port B.

Bart, ON7CCC in Oostende hears Tom calling on the Oostende repeater port C and wants to talk with Tom in Boom.

Bart in Oostende configures his radio as follows:

      YOUR : /ON0DP  B
R1 : ON0OS  C
R2 : ON0OS  G
MY : ON7CCC

 or

     YOUR : ON5BBB
R1 : ON0OS  C
R2 : ON0OS  G
MY : ON7CCC


 Bart returns the call to Tom and they have an Internet linked DV conversation.

* Notice that Bart,ON7CCC has not got a space between the YOUR call and the C. The port designator always has to be in the 8th position.

 

Important Information
D-Star User Linking and Port Linking is similar to making a telephone call or telephone conference call.

You just need to dial in the callsign you want.

As with any telephone call you Must hang up after the call.

To hang up your D-Star call when you have finished talking you must change YourCall to CQCQCQ

 

Please set your automatic GPS function always OFF  !

Use the GPS function only by "push to talk" in a QSO.

 

Additional notes:

If you are not using the repeaters in these examples, simply replace your call sign and the repeater call sign

 in your radio digital call sign configuration area for the digital repeater that you want to use.

The users in example 3 and 4 need to be pre-registered by their local repeater administration person to use Internet linking.

 Amateurs that are not registered can only listen to the internet conversation, talk locally but not talk over the internet.

These examples do not use all the different configurations that are available to the operator.

Consult the radio manual for full operation, programming, use, other options and short cuts for user and port linking.

Also, explore the digital messaging, data transfer, digital squelch, GPS operation and many other neat features.

This technology is new and we are all learning, innovating and evolving this equipment.

Practice controlling the radio and operating over the Internet will make your more proficient amateur operator.

 The radios can also be programmed manually, via front panel or with computer software.

 

You can also use the D-Star Calculator

D-STAR Calculator

 

calculator is really easy to use, we give you a few tips:

 

Select your local repeater under Source Repeater.

Choose the local repeater module that you are going to talk to, 144 MHz, 440 MHz, or 1.2 GHz.

Select the function the you want to program for. If you don't know what to choose, start with "Local Repeater with Gateway".

Choose the Destination repeater, if other than your local repeater.

Choose the Destination Repeater module, either on your local repeater, if selected as the destination, or the remote repeater if selected as the destination.

Program your radio as suggested in the next section.

For a description of what is going on, scroll to the bottom of the page.

The buddy on the left represents you, the buddy on the right indicates the station that you are going to talk to.

The two paragraphs on either side of the buddies describe what is going on.

The two paragraphs below the buddies indicate a sample initial dialog.

Notice that the picture of the modules will change dependent on your configuration.

ircDDB  ON0DP Live Log - visibility on the Internet

    

You have the choice between two options: VIS ON  means visibility on and VIS OFF means visibility off.

"VIS ON" can be activated in a very simple way.

Put "VIS___ON" in the YOURCALL field of your transceiver and press PTT once on a repeater which is connected to the ircDDB network.

After that put something different in YOURCALL, e.g. "CQCQCQ__". The setting "VIS___ON" will be stored permanently on the network.

 You only have to do this procedure once.

"VIS OFF" can be activated in a very simple way.

 Put "VIS__OFF" in the YOURCALL field of your transceiver and press PTT once on a repeater which is connected to the ircDDB network.

 After that put something different in YOURCALL, e.g. "CQCQCQ__".

 The setting "VIS__OFF" will be stored permanently on the network.

You only have to do this procedure once.
