From time to time DV Modems staff find links on the internet that they feel would be beneficial for everyone in the Amateur Radio Community. These links are listed below.

We will also have a user gallery if you would like to share a photo of your DV device working, then send you picture in and we will include it in our User Gallery


Pi-Star is a software image built initially for the Raspberry Pi (produced by the Raspberry Pi Foundation).

The design concept is simple, provide the complex services and configuration for Digital Voice on Amateur radio in a way that makes it easily accessible to anyone just starting out, but make it configurable enough to be interesting for those of us who cant help but tinker.

BrandMeister Network

BrandMaster/BrandMeister is an operating software for master servers participating in a worldwide infrastructure network of amateur radio digital voice systems.

  • If you are an amateur radio operator working in digital voice modes like D-Star, DMR, C4FM, P25 or others (not all are supported yet!!). You do not need to know much about BrandMeister, and it’s very easy to operate on its infrastructure.
  • If you are an amateur radio operator that runs a repeater in your local area, you may be interested in learning some more about BrandMeister and how you can take part in it.

A brief overview of BrandMeister core features:

  • Switching system for IP-enabled conventional Tier-2 DMR radio
  • Supports the most known network-access and end-user equipment making it easily expandable
  • Performs switching on the Layer 3 (Call Control) of the DMR stack
  • Has an embedded data stack (Layer 4)
  • Has embedded data and voice applications
  • Flexible routing based on data stored in a global database, local memory cache, and Lua scripts
  • Event notification using messaging queues (calls, connections, alarms, messages, locations and telemetry)
  • Allows one to build their own network based on mesh technology

BrandMeister allows you to connect to MOTOROLA DMR-MARC and Hytera DMRplus networks, this means you can operate with other DMR amateur radio operators on both infrastructures the same time.

OpenDMR operates PHOENIX, the largest amateur radio DMR network in the UK and DMR-DL, a large network in Germany. Additionally we provide robust, stable, high availability infrastructure and world wide talkgroup services to repeater keepers across Europe..



Our Mission is:

That we can discuss and explore new technologies, DMR radios, digital modes, computers, and that these discussions can be held in a friendly and knowledgeable environment whilst still promoting Amateur Radio.


Our network is an all-digital group of over 500 DMR-MARC repeaters with over 115000 registered users. There are over 5300 registered DMR repeaters world-wide in the RadioID database. We are all amateur radio operators many of whom are Motorola Solutions employees, Motorola Service Station employees, dealers, system installers and Motorola equipment aficionados.



This DMR ID Registration site is NOT for GMRS, FRS or Commercial DMR IDs. It is only for the Amateur Radio Service. If you are in non-Amateur services, contact those coordinators for IDs, not

The entire world is now on a Sequential MCC scheme. We DO NOT break apart the MCC for individual States/Provinces/Territories.

The MCC was never designed to function this way. It does not work well for larger countries with grouped populations.

In order to make the allocations simple and programmatically easier, Both and have agreed on using the Sequential MCC.

All Europe and Africa DMR Registrations must use the website registration. is only for North America, South America, Asia and Oceania.
