Digital Mobile Radio

The DMR-MARC Worldwide Network

The DMR-MARC network is an all-digital group of over 200 MOTOTRBO DMR repeaters in 18 countries with over 65,000 users. They are all amateur radio operators, many of whom are Motorola Solutions employees, Motorola Service Station employees, dealers, system installers, and Motorola equipment aficionados.

All repeaters on their network are connected all the time. TRBO radios have great voice quality, great coverage, and extended battery life all in LESS THAN 1/3 the channel bandwidth of a traditional analog FM repeater with TWICE as many voice channels! Their mission is to offer you a reliable and scalable choice in connectivity: local, regional, national, and international. Isn't time you upgraded to digital radio's cutting edge?



DCI MotoTRBO IPSC Amateur Radio Group

Our mission is to connect to and converse with the wider DMR Ham community by openly sharing our network resources and talkgroups to enable dynamic connections to all radio amateur DMR groups.

Our focus is to learn more about and experiment with, IPSC, c-Bridge implementation and 3rd party networking options compatible with MotoTRBO IPSC networking. You only need a DMR capable user radio but you must use or have access to a Motorola MotoTRBO repeater.


The North Carolina PRN system is a fully digital UHF repeater system that utilizes an ETSI Standard called Digital Mobile Radio, or DMR. Their repeaters are linked full time to create a wide-area repeater system that covers parts of Virginia, North Carolina and South Carolina. They also utilize on-demand linking that allows a user to connect with others around the world. Each of their repeaters are able to support two voice conversations at the same time. So, while a user in Raleigh, NC is talking to a user in Columbia, SC, another user can be talking to someone across town, in the Southeast, or around the world.
