Getting Started on DMR 

Getting started with DMR is easy! Just follow the four steps below and you’ll be up and running in no time!

1. Check for DMR Coverage

Verify that you are within the coverage area of the  DMR repeaters in East Tennessee. At present, there are DMR repeaters in Knoxville (KB4REC), Morristown (N4FNB), Greeneville, (K4MFD), and Chattanooga (W4PL).  There is also a Brandmeister repeater in Gallatin (Nashville Area)- (WD4BKY/K4OZE) Coverage maps can be created and reviewed on the Brandmeister Network  website.

2. Get a Subscriber ID

All radios on ham radio DMR networks require a unique Subscriber ID, so you will need to have one assigned before you can program your radio to operate on a DMR repeater. If you intend to have more than one DMR radio active at any given time, then you should request a Subscriber ID for each radio.

Apply for a Subscriber ID

Within about 24 hours, you should receive your Subscriber ID via email. Please do not transmit with your DMR radio until you have received a Subscriber ID and have this programmed into your radio. Using ad-hoc Subscriber ID numbers will cause conflicts with other users on the network.

3. Obtain a DMR Radio

Obtain a DMR radio, the programming software and cable (if required for your desired radio model) from one of the sources listed on the VA3XPR FAQ page.

4. Program your DMR radio

Program your DMR radio using the DMR repeater specifications found on the DMR-MARC repeater map or, the  Brandmeister Network website by clicking on DMR repeaters in your local area, plus the Subscriber ID you received via e-mail. Here is a link to several "YouTube" videos for DMR radio programming. There are also pre-programmed codeplugs available for certain types of radios, depending on your radio brand and location.  Contact Tim, WB4GBI, for further information. An email link is located on the home page of this website.

* TN Statewide Only On Time Slot 2
* No Private Calls Allowed


A talk group which is “always on” meaning it is static or always sent to the repeater on the assigned time slot without any user intervention.


On demand talk groups are available dynamically meaning it is only sent to the repeater when a local user keys up that talk group. The talk group will be sent to the repeater for a period of 15 minutes after the most recent key up by a local user.


The BM talk group for each repeater sets a talkgroup to match the repeater's ID number. Now you can bring up one of the repeaters from ANY where worldwide if you have a BrandMeister connected repeater or hotspot.  Please note these talk groups are On Demand and would have to be brought up here local for the guest via the web to be heard locally.  

 

Thanks to Jeff, K4MFD, for the list above!
