Digital Mobile Radio (DMR) Resources for Amateur Radio
Find guides, networks, and repeater information to help you get started with or expand your use of DMR in amateur radio.
Digital Mobile Radio, or DMR, offers ham radio operators a modern digital voice mode for local and wide-area QSOs. It uses Time-Division Multiple Access (TDMA) to allow two simultaneous conversations on a single repeater frequency, making efficient use of spectrum. Hams use DMR for clear voice communication, often linking repeaters over IP networks to connect with other stations globally. Setting up a DMR station involves obtaining a unique DMR ID and configuring a radio with a code plug specific to local repeaters and talkgroups.
This category provides resources for hams getting started with DMR, including guides on how to register for a DMR ID and create code plugs for radios. Operators can find information on major networks like DMR-MARC and Brandmeister, along with regional groups such as NOCO DMR Group and New England DMR. There are also repeater maps and comparisons of DMR with other digital modes like D-STAR, helping operators understand the technology and its practical applications.
