JMM is hardware. The first to be released commercially, was a 2-meter mobile unit designated IC-2200H. Icom followed up with 2 meter and 440 MHz handheld transceivers the next year.

However, the yet to be released UT-118 add-on card was required for these radios to operate in D-STAR mode. Eventually, the card became available and once installed into the radios, it provided D-STAR connectivity.

The two experienced minor difficulty with during the QSO. As of late 2009, there are around 10,800 D-STAR users talking through D-STAR repeaters with Internet connectivity via the G2 Gateway. There are approximately 550 G2 enabled repeaters now active. Note, these numbers do not include users with D-STAR capabilities that are not within range of a repeater, or working through D-STAR repeaters that do not have Internet connectivity. The first D-STAR capable microsatellite was launched in early 2016. OUFTI-1 is a built by Belgian students at the and I.S.I.L.

The name is an acronym for Orbital Utility For Telecommunication Innovation. The goal of the project is to develop expertise in various aspects of satellite design and operation.

The satellite weighs just 1 kilogram and utilize a UHF uplink and a VHF downlink. In 2015, FlexRadio Systems added D-STAR support to their line of transceivers and receivers via a software upgrade. D-STAR support requires the addition of the ThumbDV device from NW Digital Radio. Technical details The system today is capable of linking together locally and through the Internet utilizing callsigns for routing of traffic. Servers are linked via utilizing proprietary 'gateway' software, available from Icom.

There is also an interlinking radio system for creating links between systems in a local area on 10 GHz, which is valuable to allow emergency communications oriented networks to continue to link in the event of internet access failure or overload. Within the D-STAR Digital Voice protocol standards (DV), voice audio is encoded as a 3600 bit/s data stream using proprietary encoding, with 1200 bit/s FEC, leaving 1200 bit/s for an additional data 'path' between radios utilizing DV mode.

On air bit rates for DV mode are 4800 bit/s over the 2 m, 70 cm and 23 cm bands. In addition to digital voice mode (DV), a Digital Data (DD) mode can be sent at 128 kbit/s only on the 23 cm band. A higher-rate data protocol, currently believed to be much like ATM, is used in the 10 GHz 'link' radios for site-to-site links. Radios providing DV data service within the low-speed voice protocol variant typically use an or connection for low speed data (1200 bit/s), while the Icom ID-1 23 cm band radio offers a standard connection for high speed (128 kbit/s) connections, to allow easy interfacing with computer equipment. Gateway server The current gateway control software rs-rp2c version G2, more commonly called 'Gateway 2.0'. Though most Linux distributions should be suitable, the recommended configuration uses CentOS Linux 5.1 with the latest updates, typically running ( 2.4.20. 2.3.2 and 9.2.1 or later).

The CPU should be 2.4 GHz or faster and the memory should at least be 512 MB or greater. There should be two and at least 10 GB free of hard drive space which includes the OS install. Finally for middleware, 2.0.59, 5.5.20, modjk2 2.0.4, 0.9.8d, 5.0 and 8.2.3 are utilized, but these can be different as updates occur. Along with the open-source tools, the Icom proprietary dsipsvd or 'D-STAR IP Service Daemon' and a variety of entries utilize a mixture of the local PostgreSQL and BIND servers to look up callsigns and 'pcname' fields (stored in BIND) which are mapped to individual 10.x.x.x internal-only addresses for of both voice and data traffic between participating gateways. During installation, the Gateway 2.0 software installation builds most of the Web-based open-source tools from source for standardization purposes, while utilizing some of the of the host Linux system, thus making CentOS 5.1 the common way to deploy a system, to keep incompatibilities from occurring in both package versions and configuration. Additionally, gateways operating on the U.S.

Trust server are asked during initial setup to install DStarMonitor which is an add-on tool that allows the overall system administrators to see the status of each Gateway's local clock and other processes and needed for normal system operation, and also sends traffic and other data to servers operated under the domain name of 'dstarusers.org'. By this means a complete tracking of user behaviour is technically possible. Pentium r dual core cpu e5500 drivers for mac. Installation of this software also includes JavaAPRSd, a Java-based interface which is utilized on Gateway 2.0 systems to interface between the Icom/D-STAR GPS tracking system called DPRS to the more widely known and utilized amateur radio APRS system. How Gateway G2 works Each participating amateur station wanting to use repeaters/gateways attached to a particular trust server domain must 'register' with a gateway as their 'home' system, which also populates their information into the trust server—a specialized central gateway system—which allows for across a particular trust server domain.

Only one 'registration' per trust domain is required. Each amateur is set aside eight 10.x.x.x internal for use with their callsign or radios, and various naming conventions are available to utilize these addresses if needed for specialized callsign. Most amateurs will need only a handful of these 'registered' IP addresses, because the system maps these to callsigns, and the callsign can be entered into multiple radios. The gateway machine controls two, the 'external' one being on a real 10.x.x.x network behind a router.

A router that can perform on a single public IP address (can be static or dynamic in Gateway G2 systems) to a full 10.x.x.x/8 network is required. From there, the Gateway has another NIC connected directly to the D-STAR repeater controller via and the typical configuration is a 172.16.x.x (/24) pair of addresses between the gateway and the controller. Differences between Gateway V1 and G2 The main differences between Gateway V1 and V2 are the addition of a for more flexibility and control of updates, versus the previous use of only for 'database' activities, the addition of both an administrative and end-user Web interface for registration which was previously handled via commands by the Gateway V1 system administrators, dropping the requirement for static public for, and the ability of the software to use a to find and communicate with the trust server, allowing for redundancy/failover options for the trust server administrators. Finally, a feature called 'multicast' has been added for administrators to be able to provide users with a special 'name' they can route calls to which will send their transmissions to up to ten other D-STAR repeaters at the same time. With cooperation between administrators a 'multicast group' can be created for multiple repeater networks or other events.

Another additional feature of Gateway G2 is the ability to use callsign 'suffixes' appended to the user's callsign in a similar fashion to the repeaters and gateways in the original system, which allow for direct routing to a particular user's radio or between two user radios with the same base callsign, by utilizing the 8th most significant field of the callsign and adding a letter to that location, both in the gateway registration process on the web interface, and in the radios themselves. Gateway V1 control software The Gateway V1 software was similar to Gateway G2, and utilized Fedora Core 2+ or Red Hat Linux 9+ OS on a Pentium-grade 2.4 GHz or faster machine. IrcDDBGateway Gateway software developed by Jonathan Naylor, G4KLX, has a larger network of repeaters and users and is being adopted by former Gateway G2 users as the G2 system is closed source, only supports Icom repeaters, and runs on Centos 5.x which will reach end of life in March 2017. IrcDDBGateway operates on the ircDDB and QuadNet2 networks. IrcDDBGateway supports Icom controllers and repeaters, as well as homebrew repeaters and hotspots (simplex access points). It provides more linking and routing options over the Gateway V1 and G2.

IrcDDBGateway can run on various distributions of Linux and versions of Microsoft Windows. Computer requirements can be as simple as a. Add-on software Various projects exist for gateway administrators to add 'add-on' software to their gateways, including the most popular package called 'dplus' created by Robin Cutshaw AA4RC. A large number of Gateway 2.0 systems are offering services added by this software package to their end-users, and users are getting used to having these features.

Features include the ability to link systems directly, 'voice mail' (a single inbox today), ability to play/record audio to and from the repeaters connected to the Gateway and the most important, the ability for DV-Dongle users to communicate from the Internet to the radio users on the repeaters. There is often a misconception by users and system administrators alike that the Gateway 2.0 systems have these add-on features from dplus by default, a testament to the popularity of this add-on software. Dplus software development has an active following, and features such as multiple repeater/system connections similar to the type of linking done by other popular repeater-linking systems ( and ) are being worked on. Criticisms Proprietary codec Like other commercial digital modes (, System Fusion), D-STAR uses a closed-source proprietary voice codec that's patented by Digital Voice Systems, Inc. (DVSI) because it was the highest quality and only codec available in silicon when the system was released.

Unfortunately, amateur radio operators do not have access to the specification of this codec or the rights to implement it on their own without buying a licensed product. Amateurs have a long tradition of building, improving upon and experimenting with their own radio designs.

The modern digital age equivalent of this would be designing and/or implementing codecs in software. Critics say the proprietary nature of AMBE and its availability only in hardware form (as ICs) discourages innovation. Even critics praise the openness of the rest of the D-STAR standard which can be implemented freely. Trademarked name Despite many protestations from the Pro-D-STAR lobby that the standard was developed by the JARL and D-STAR is not only an Icom system, the mark 'D-STAR' is itself a registered trademark of Icom. According to the United States Patent and Trademark Office, a trademark is defined as 'a word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party from those of others.' Icom does hold a trademark for its stylized D-STAR logo. There is no indication Icom is charging other vendors to use any of the D-STAR branding.

Usable range compared to FM D-STAR, like any digital voice mode has comparable usable range to FM, but it degrades differently. While the quality of FM progressively degrades the further a user moves away from the source, digital voice maintains a constant voice quality up to a point, then essentially '. This behavior is inherent in any digital data system, and it demonstrates the threshold at which the signal is no longer correctable, and when data loss is too great, audio artifacts can appear in the recovered audio. Emergency Communications Concerns Many advanced D-STAR features rely on internet connections although simplex, repeated and crossband gateway voice and data communications do not.

During widespread disasters that compromise commercial telecommunications infrastructure, D-STAR systems (as well as other modes that rely on the internet) may suffer outages or feature degradation that impacts operations. Without simulating such outages during drills, it is difficult to assess the impact of or establish D-STAR service recovery procedures in the event of such failures. As of the fall of 2011, there has been almost no discussion in the ham radio literature regarding actual drills where D-STAR systems were tested with completely failed or even intermittent telecommunications infrastructure. Comprehensive emergency communications plans used by ARES and other such organizations should address the possibility that such systems may not function as intended during major disasters. The loss of Internet does not degrade the local operation of a D-STAR repeater system. Over the Internet linking and routing of traffic may be degraded. Some groups are using microwave based systems, such as HamWAN, to link repeaters.

Cost In 's radio line, D-STAR does significantly add to the cost of a radio, which is a barrier to the adoption of the technology. In 2006 the cost of a D-STAR radio was compared to that of a standard analog radio, and the price difference was nearly double. This is due partly to the per-unit cost for the voice codec hardware and/or license and partly to manufacturer research and development costs that need to be amortized. As is the case with any product, as more units are sold, the R&D portion of the cost will decrease over time.

The D-STAR capable radios also cost more than their equivalents from other brands, even before the D-STAR options boards are added (in the UK as of April 2011, Martin Lynch & Sons' website lists the Icom 2820 (without D-STAR) at £489, while the equivalent Yaesu, the FT8800, is listed at just £337). FlexRadio Systems D-STAR implementation requires the use of a $129 add-on module to their FLEX-6000 Series Radios.

Questionable legality Many have argued that the proprietary codec constitutes a form of encryption, and encryption is prohibited by almost every country's amateur radio licence conditions. According to FCC rules, if the algorithm is publicly published or otherwise widely available enough that transmissions are not secret, it is considered encoding rather than encryption. Unfortunately D-STAR uses AMBE, a non public codec. However, French regulators, in April 2010, have issued a statement that rules D-STAR illegal in France, due to the ability to create a connection to the internet with it and the proprietary nature of the codec used.

The French Amateur Radio society, DR@F - Digital Radioamateur France has an online petition against this ruling, calling for the government to allow the mode, as to ban it would deny them 'fundamental rights'. Non-Icom D-STAR Repeaters The world's first non-Icom D-STAR repeater GB7MH, fully linked to the K5TIT G2 network and D-Plus, went live on 10 September 2009, in West Sussex, England.

Whilst waiting for the DSL line installation, the repeater is connected to the Internet via a 3G dongle from network operator 'Three'. The system is built around Satoshi Yasuda's GMSK Node Adapter, a Mini-ITX system running CentOS 4, a Tait T800 repeater and G2 code written by G4ULF.

All the usual G2 features such as callsign routing, D-Plus linkage and DPRS via D-STAR Monitor are supported. Today a home-brewed D-STAR repeater can be built using open source software, used commercial radio equipment and a computer.

One group advocating the construction of home-brewed D-STAR repeaters is Free-Star. Free-Star is an experimental approach to the implementation of a vendor neutral, and open source, digital communication network for amateur radio. Compatible programs and projects D-StarLet A Web-based text messaging application using D-STAR digital data technology. D-StarLet is an open source client-server solution that allows content creation and modification from certain persons. D-StarLet interfaces with a D-STAR radio through the serial port.

Served agencies can relate to sending or other documents to someone. The quantity of data sent can be higher compared to traditional amateur modes. Voice and even are capable of getting a message through albeit slowly, but D-STAR can transfer documents, images,. It was in the the Washington County ARES group was able to test D-STAR during this series of several strong Pacific storms that interrupted conventional communication systems for up to one week.

Primary emergency traffic for the and the Fire Department was handled by the group using traditional FM voice because the group had no D-STAR repeater equipment available. Once the situation's communication needs became established the D.Chat messaging function was used to send small text transmissions via D-STAR at distances of up to seventeen miles. An ability for amateurs to send files during this weather event would have greatly increased the capacity for ARES to help during the emergency. Although D.Chat was a useful means of communication D-RATS was developed to help fill the gaps that may have been lacking. Another improvement over D.Chat that D-RATS provides is form support. Users can set up frequently used forms well before they're necessary and when the need comes all that's required is to fill in the fields.

In this way, for example, emergency forms from the, or the, such as the FEMA standard ICS-213, could be generated and sent. Home-brew D-STAR radio.

ICOM IC-91AD handheld transceiver with the D-STAR UT-121 digital voice board installedD-STAR ( Digital Smart Technologies for Amateur Radio) is a digital voice and data protocol specification for. The system was developed in the late 1990s by the and uses in its -based standard. There are other digital modes that have been adapted for use by amateurs, but D-STAR was the first that was designed specifically for amateur radio.Several advantages of using digital voice modes are that it uses less than older analog voice modes such as. The quality of the data received is also better than an analog signal at the same, as long as the signal is above a minimum threshold and as long as there is no. D-STAR compatible radios are available for, and microwave 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, allowing streams of voice or packet data to be routed via amateur radio.D-STAR compatible radios are manufactured by, and FlexRadio Systems. Contents.History In 1998 an investigation into finding a new way of bringing digital technology to amateur radio was started. The process was funded by a ministry of the Japanese government, then called the, and administered by the.

In 2001, D-STAR was published as the result of the research.In September 2003 Icom named Matt Yellen, KB7TSE (now K7DN), to lead its US D-STAR development program.Starting in April 2004 Icom began releasing new 'D-STAR optional' hardware. The first to be released commercially, was a 2-meter mobile unit designated IC-2200H. Icom followed up with 2 meter and 440 MHz handheld transceivers the next year.

The June 2005 edition of the ARRL's reviewed the Icom IC-V82.JARL released some changes to the existing D-STAR standard in late 2004. Icom, aware that the changes were coming, delayed the release of their hardware in anticipation of the changes.The Icom ID-1 1.2 GHz mobile radio was released in late 2004. The ID-1 was the first and only D-STAR radio that provides digital data (DD) mode operation. In this mode, data can be transferred at 128 kbit/s as a wireless bridge via the RJ-45 Ethernet jack on the radios.The first D-STAR occurred between Michael, N3UC, FM-18 in and Robin, AA4RC, EM-73 in while working AMSAT's AO-27 microsatellite in 2007. The two experienced minor difficulty with during the QSO.As of late 2009, there are around 10,800 D-STAR users talking through D-STAR repeaters with Internet connectivity via the G2 Gateway. There are approximately 550 G2 enabled repeaters now active. Note, these numbers do not include users with D-STAR capabilities that are not within range of a repeater, or working through D-STAR repeaters that do not have Internet connectivity.The first D-STAR capable microsatellite was launched in early 2016.

OUFTI-1 is a built by Belgian students at the and I.S.I.L. The name is an acronym for Orbital Utility For Telecommunication Innovation. The goal of the project is to develop expertise in various aspects of satellite design and operation. The satellite weighs just 1 kilogram and utilizes a UHF uplink and a VHF downlink.In 2015, FlexRadio Systems added D-STAR support to their line of transceivers and receivers via a software upgrade. D-STAR support requires the addition of the ThumbDV device from NW Digital Radio. Technical details The system today is capable of linking together locally and through the Internet utilizing callsigns for routing of traffic. Servers are linked via utilizing proprietary 'gateway' software, available from Icom.

This allows amateur radio operators to talk to any other amateurs participating in a particular gateway 'trust' environment. The current master gateway in the United States is operated by the K5TIT group in Texas, who were the first to install a D-STAR repeater system in the U.S.D-STAR transfers both voice and data via digital encoding over the (VHF), (UHF), and (1.2 GHz) amateur radio bands. There is also an interlinking radio system for creating links between systems in a local area on 10 GHz, which is valuable to allow emergency communications oriented networks to continue to link in the event of internet access failure or overload.Within the D-STAR Digital Voice protocol standards (DV), voice audio is encoded as a 3600 bit/s data stream using proprietary encoding, with 1200 bit/s FEC, leaving 1200 bit/s for an additional data 'path' between radios utilizing DV mode.

On air bit rates for DV mode are 4800 bit/s over the 2 m, 70 cm and 23 cm bands.In addition to digital voice mode (DV), a Digital Data (DD) mode can be sent at 128 kbit/s only on the 23 cm band. A higher-rate data protocol, currently believed to be much like ATM, is used in the 10 GHz 'link' radios for site-to-site links.Radios providing DV data service within the low-speed voice protocol variant typically use an or connection for low speed data (1200 bit/s), while the Icom ID-1 23 cm band radio offers a standard connection for high speed (128 kbit/s) connections, to allow easy interfacing with computer equipment. Gateway server The current gateway control software rs-rp2c version G2, more commonly called 'Gateway 2.0'. Though most Linux distributions should be suitable, the recommended configuration uses CentOS Linux 5.1 with the latest updates, typically running ( 2.4.20.

2.3.2 and 9.2.1 or later). The CPU should be 2.4 GHz or faster and the memory should at least be 512 MB or greater.
