<strong>DIGITAL</strong> HAM INNOVATIONWITH <strong>DIGITAL</strong> VOICE & HIGH SPEED DATAWhat is D-STAR?D-STAR is a new ham radio system which offers digital voice anddata communication. It connects repeater sites over microwave linksand the Internet and forms a wide area ham radio network. The D-STAR system provides a new capability and functionality to the hamradio world and increases the efficiency of emergency communications.What can the D-STAR system do?128kbps digital data and 4.8kbps digitalvoice communicationThe D-STAR system provides not only digitalvoice (DV mode) communication butalso digital data transmission (DD mode). Itcan exchange various data files such asgraphics, images, etc, at 128kbps.Your voice and data can reach further than everMultiple repeater links by radio and the Internet provide long distancecommunication to virtually anywhere.Internet application availableThe D-STAR system uses the TCP/IP protocol,so when connected with a PC, web,e-mail and other Internet applications areavailable.Wireless Internet AccessNo matter where you travel within the D-STAR network, you can access the web,e-mail, text messages and multimediamessages.Independent networkIn DD mode, ID-1 can transfer data directly with another ID-1 withoutthe use of a repeater. This is useful for establishing a simple networkwhere a D-STAR repeater does not exist or D-STAR servicesare not required.Increase efficiency of emergency communicationsOut in the field, fast emergency information is the key. Send picturesand weather charts to or from a remote location with the ID-1. “Apicture is worth a thousand words”, and efficient send/receive opensup your repeater for other emergency communications.D-STAR system will be upgradedThe D-STAR system will be enhanced and new D-STAR radios willbe released, adding features and performance to the D-STAR system.D-STAR repeater systemThe D-STAR repeater is composed of a repeater controller, 1.2GHzdigital voice repeater, digital data repeater, 10GHz microwave relayand the Internet gateway PC. For the signal is digital data, no informationis lost due to conversion and multiple repeater relays arepossible in this system. The D-STAR system repeater can perform 3relay functions as shown in the following figures.Single repeaterThe D-STAR repeater operates similar to existing analog repeater.That is a simple relay of transmit and receive communication in1.2GHz band.Single repeaterStation A1.2GHzMicrowave linkWhen D-STAR repeaters are connected via 10GHz microwave, theD-STAR system transfers a received data to another repeater site.You can also make a CQ call to a specified repeater area.Microwave linkStation ARepeatersite 11.2GHzInternet gateway relay1.2GHz1.2GHz digital voice and data repeater10GHz relay10GHz relayRepeatersite 21.2GHz1.2GHz digital voice/data repeater and 10GHz microwave linkStation BStation CWhen D-STAR repeaters are connected with the Internet gateway,the D-STAR system relays the received INTERNET data over the Internet. Microwavelinks and Internet gateways can be combined even duringone contact. So your message will get through virtually to anywherein the D-STAR system.Internet gateway relay1.2GHzStation ARepeatersite 110GHz relayRepeater INTERNETsite 2Repeatersite 31.2GHzGatewayGatewayINTERNET1.2GHz digital voice/data repeater and Internet gatewayStation D
