Step 1: DMR - Radio, Specifically for the Anytone D878 UV 2 Super But Should Be Useful for Others

Getting started on the Anytone 878UV2 - Basic programming to get you started using the Anytone AT-D878UV II Super, though this information should work for most models. Ensure you download the correct firmware and software for your model. - https://youtu.be/dmTKW6E3W_Y

DMR setup and using it to make contacts -I show how to add a new DMR Chanel, create a Talk Group, and add it to a Zone on the Anytone AT-D878UVII. This info should also work for many other DMR radios too with minor adjustments. It is the order of events that is the most important. - https://youtu.be/dNkdYzQbISY

DRM setup update! - Anytone D878 Repeater Import -*** Since making this video I prefer to create the code plug manually, you will learn and understand more! *** I found a real time saving way to import all repeater settings for this and many other radios! So I wanted to share it with you all so you can save time too and increase the chances of opening repeaters - https://youtu.be/V-KrZ3kP2vA *** Since making this video I prefer to create the code plug manually, you will learn and understand more! ***

Step 2: DMR - How It Works and How to Get Set Up

And why you shouldn’t import too many repeaters to your codeplug like I did!

I have made an accompanying video on YouTube at https://youtu.be/dNkdYzQbISY

Setting up DMR takes some patience but once you access the repeaters and talk groups you will be rewarded with many QSOs from all over the world in glorious digital quality.


DMR (Digital Mobile Radio) is a great transmission/reception mode, it is clear audio in a resilient wrapper that can withstand a lot of QRM - interference and fading. It is pretty much either working, or not with no real distortion. It has been developed due to the availability of cheap micro processors which can process audio into digital encoding and manage complex transmission systems. The DMR amateur radio system allows people to talk one to one or through a repeater in either simplex mode (same TX and RX frequencies) or duplex mode. You can probably access many DMR repeaters in your surrounding area and they provide access to hundreds of talk groups. Now modern DMR Transceivers have thousands of memories for channels, talk groups and contacts, so it is very tempting to try and import everything just in case. BUT YOU SHOULDN’T! I will be explaining why, but first let’s have a look at how DMR manages to do many things, all within the ‘limited’ bandwidth of a repeater.

DMR Mode


DMR sits on a frequency like any other transmission mode, but it uses a different modulation system and it takes a lot more control over how the signal is transmitted. This is necessary to allow the operator's radio to synchronise with the receiving transceiver or repeater. To understand this we need to look at several factors that are pretty ‘out there’ compared to FM or SSB transmissions.
