Descripción sencilla Es una red mundial libre de repetidores de tecnología DMR, para su uso en las Bandas de Radioaficionados. Todos ellos se interconectan a través de unos servidores en Internet, que se llaman «master». Los master se interconectan entre sí en una estructura en estrella «todos contra todos». Los usuarios se conectan mediante un…
Why? [ I wrote these two introductory paragraphs in 2016, shortly after learning how to use D-STAR. I’ve been updating the rest of the article regularly as I learn more.] After weeks of intense learning and effort, I felt like I was just beginning to get a handle on D-STAR, having put together a nicely working…
Introduction Pi-Star is great software for digital voice hotspots and repeaters. It can handle DMR, D-STAR, and YSF, as well as P25, NXDN, POCSAG, and some cross modes when used with a multi-mode digital voice modem that supports those modes. Andy Taylor, MW0MWZ, the main developer, says this on his Pi-Star website△:“Pi-Star can be whatever you…
DMR (Radio móvil digital): Es una norma de transceptores móviles digitales específica para los usuarios de móviles profesionales (PMR, Professional Mobile Radio). Es desarrollada por el Instituto Europeo de Normas de Telecomunicaciones (European Telecommunications Standards Institute, ETSI) y ratificada por primera vez en 2005. Nace con el fin de conseguir una mejora de la eficiencia espectral sobre la radio analógica tradicional…
Introduction: “The nice thing about standards is there are so many to choose from.” I love the ironic humour in this statement; a standard should result in everyone doing things the same way in order to be compatible, and prevent having to constantly re-invent the wheel. Yet, everyone has to have their own standard! Just…
What Is The DMR-MARC Network MARC stands for Motorola Amateur Radio Club Worldwide Network. It is one of the original DMR network coordinators and is still to this day extremely popular and reliable.

What Is A Talkgroup? A DMR talkgroup is simply a way of grouping many Radio IDs into a single digital contact. Or put another way, a talkgroup is a method of organizing radio traffic specific to the DMR users that all want to hear the same thing and not be bothered by other radio traffic…
The Radio ID Database The Motorola Amateur Radio Club World Wide Network has been in existence for many years. MARC was the first organization to get a foothold in the amateur radio world and as such, had at one time become the defacto owner of radio and repeater DMR IDs. The DMR-MARC network started out…
DMR stands for Digital Mobile Radio and uses the Motorola TRBO protocol for communications. Like other digital modes such as D-Star, C4FM and APCO P25, the TRBO protocol converts your voice into a digital form and sends it out via RF (with other bits of information included) and allows you to communicate to other DMR…
