BrandMeister DMR repeater sysops: how to create a “local talkgroup” on your repeater

BrandMeister Repeater Sysops : How to create a “local talkgroup” for your repeater ?

Repeater owners like to offer a talkgroup dedicated for hams within the coverage area of the repeater and refer to it as the “local talkgroup”. This can be achieved two ways, depending if you want a talkgroup:

1) that only local users within the repeater coverage can use

As you know, all valid talkgroups numbers are routed between BrandMeister master servers. There is however an exception for talkgroups 1 through 90. QSOs on these talkgroup numbers will never route past the repeater.

Considering that single-digit talkgroup numbers are usually used for clusters, using a talkgroup number between 10 and 90 for your local-only talkgroup(s) is a good choice.

One might think that Talkgroup 9 on Timeslot 2 is an option because traffic doesn’t seem to route. However it is not a good idea because TG9/TS2 is dedicated for reflector usage. As soon as someone connects a reflector on the repeater: all the traffic that users think is local on TG9/TS2 is now broadcasted on the matching talkgroup on the worldwide BrandMeister without them knowing! (unless the connected master is configured to disable reflectors, but better be safe than sorry!).

2) that is dedicated to the local community of the repeater users but also available outside of the coverage area if someone travels and want to use a different repeater or hotspot to talk to hams at home

What is recommended in this case is to simply use a talkgroup number that matches the 6-digit DMR ID of the repeater. This avoid any possible collision if choosing an arbitrary talkgroup number, since all repeaters have a unique ID on the BrandMeister network. 4-digit and 5-digit talkgroups are usually dedicated to regional talkgroups. There no need to make this talkgroup static since it is for the repeater’s local users.

Please configure a personalized security password for your hotspots !

What are hotspot passwords ?

As you may know, hotspots connecting to a BrandMeister master server using homebrew or MMDVM protocol require a password to connect. Currently most of you use the “master server password” which is typically published on the corresponding country’s BrandMeister wiki page. Some software packages include those default passwords, relieving the users from needing to research and input this password.

It is also possible, and now strongly recommended for each user to setup their own personalized password from within the BrandMeister Selfcare.

Why setting up a personalized hotspot password for your own callsign ?

If you did not setup a personalized password for your hotspot, anyone can configure their hotspot with your personal DMR ID and connect with the master’s publicly documented default password, and start using the hotspot with your callsign !

Unfortunately this is happening more and more, thus our recommendation for everyone to setup a personalized password. By creating your own password, you ensure that you are the only one able to use your DMR ID to setup a hotspot.

Also setting up your own password will prevent your hotspot connection to stop working when the password is changed on the master you are connecting to.
