This guide walks you through every step – from choosing your first DMR radio and getting your unique DMR ID to programming a simple codeplug and making your first digital QSO. Whether you’re brand-new to ham radio or just curious about going digital, you’ll be on the air in no time.
For many new hams, the first taste of digital voice often comes with DMR, which is short for “Digital Mobile Radio”. Originally developed for commercial two-way radio users, DMR has been embraced by the ham community for its crisp audio, efficient use of spectrum, and the thrill of connecting with operators worldwide over the Internet.
If you’ve just earned your ticket and want to explore digital modes, this guide will walk you through the entire process, from buying your first radio to making your very first digital QSO.
1 DMR for Beginners: Meet DMR
DMR works differently from analog FM. Instead of sending your voice as a continuous audio wave, it compresses it into digital data using the AMBE+2 codec. That makes your audio stay clear and consistent until you reach the edge of coverage, unlike analog FM, which fades gradually into the noise.
Another DMR hallmark is TDMA (Time-Division Multiple Access): a single 12.5-kHz channel is divided into two alternating time-slots, so two conversations can share the same frequency. Hams also use talkgroups, which are virtual chat rooms, that let you join conversations by region, country, or interest.
2 Picking Your First DMR Radio
Your journey begins with choosing a DMR radio. Many newcomers start with a handheld DMR unit such as the Radioddity GD-88, Anytone AT-D878UV II, or TYT MD-2017. If you want more power and a bigger display for the car or shack, mobile rigs like the Anytone AT-D578UV III Pro or TYT MD-9600 are good bets.
Some hams prefer commercial-grade radios like the Motorola XPR-7550e or Hytera PD-782, which are often available second-hand but can be more challenging to program. Whatever you choose, invest in a reliable programming cable, as many headaches come from cheap knock-offs that fail to communicate with your computer. Also consider whether the programming software is readily available; for example, software for some Motorola DMR radios may require an additional paid license.
3 Get Your DMR ID
Before you can key up on a DMR network, you’ll need a DMR ID – a unique numeric ID linked to your callsign so that your name and call appear on other operators’ screens.
Head over to RadioID.net and register an account. You’ll upload a scan of your amateur radio license, then wait a day or two for approval. Once you have your DMR ID, keep it handy for programming later.
4 Setting Up the Programming Software
Unlike analog rigs that you can program entirely from the keypad, DMR radios use codeplugs, which are configuration files that store all your frequencies, channels, talkgroups, and button assignments.
Download the Customer Programming Software (CPS) from your radio’s manufacturer, install it on your computer (most require Windows), and plug in your radio with the programming cable. The first thing to do is read and save the existing codeplug so you can restore it if something goes wrong.
5 Finding Your Local DMR Repeaters
If you don’t have an existing codeplug you can use, then you you’ll need to know where you can actually reach the network. Check RepeaterBook.com, your local club’s website, or the repeater map on the RadioID.net to find DMR repeaters in your area.
Make a note of each repeater’s frequency, color code (like a digital version of CTCSS), which timeslot is used for which talkgroups, and the names or numbers of the talkgroups you’re interested in.
6 Building Your First Codeplug
Armed with that information, you can start programming. Create a contact list of the talkgroups you plan to use – maybe TG 91 (Worldwide), TG 302 (Canada), and your local club TG. Then build channels by pairing each repeater’s frequency, color code, timeslot, and talkgroup.
Most radios also use zones, which are essentially folders of channels that make it easier to navigate, for example a “Local DMR” zone for your city and a “Travel” zone for nearby regions. Once your basic channels and zones are ready, write the codeplug to your radio.
Pro Tip: Many clubs share codeplugs for popular radios. Downloading one of these can save you hours of work.
7 Making Your First Digital QSO
Now comes the fun part – getting on the air!
Before you call CQ, try the Parrot talkgroup (often TG 9990 on many BrandMeister repeaters and hotspots). When you key up on Parrot talkgroup and speak, the network plays your audio back to you a few seconds later. If you hear your own voice echo back, you know your radio, codeplug, and network connection are all working properly.
Once you’ve confirmed everything, pick an active talkgroup, listen for a moment to avoid doubling over someone, then key up and say:
“This is [your callsign], testing my new DMR radio. Any station copy?”
Chances are someone will answer and welcome you aboard the network—that’s your first digital contact, congratulations!
8 Going Beyond the Local Repeater
Once you’re comfortable, you’ll find that DMR isn’t limited to big club repeaters. Personal hotspots like the Pi-Star-based MMDVM, SharkRF OpenSpot, or BridgeCom SkyBridge let you connect to the network from anywhere with Wi-Fi, which perfect for use at home, at the cottage or while traveling.
Some mobile radios even support roaming, which automatically selects the strongest repeater as you drive through different coverage areas. You can also experiment with other networks such as TGIF for a different variety of talkgroups.
9 A Word on DMR Etiquette
DMR is a shared resource, so good operating habits keep things smooth for everyone. Avoid “kerchunking” (keying up without ID), keep transmissions reasonably short, and pause between overs to let the network link or unlink talkgroups. And of course, always identify with your callsign as required by your country’s amateur-radio regulations.
For further guidance, it’s worth revisiting the timeless Amateur’s Code, first written by Paul M. Segal, W9EEA, in 1928. Its principles—being considerate, loyal, progressive, friendly, balanced, and patriotic—still serve as a benchmark for how we conduct ourselves on the air. Applying these values to DMR ensures our conversations remain courteous, helpful, and enjoyable for everyone who shares the network.
10 Keep Learning
As you gain experience, you can try advanced features like GPS and APRS over DMR, short text messaging, Bluetooth programming, or firmware updates that unlock new functions. These extras aren’t essential to get started, but they’re fun ways to grow with the mode.
11 Final Thoughts
Getting on DMR can seem a little intimidating at first – especially compared to the simplicity of a VHF analog FM radio, but once you break it into steps, it’s very manageable. Secure your DMR ID, program a handful of repeaters and talkgroups, and you’ll be making worldwide contacts in no time.
DMR has helped bring fresh energy to ham radio, and joining in is one of the best ways to see how digital voice is shaping the hobby’s future.
