New talkgroup 98 dedicated to tests

There is now a dedicated international talkgroup on BrandMeister for all your tests: TALKGROUP 98.

You can test the audio on your new radio or software as many times as you want, for as long as you want, without worrying to disrupt a QSO.

If you like helping fellow digital ham operators, please stand-by on this talkgroup whenever you can to provide assistance and feedback.

73’s and happy tests on talkgroup 98 !

Hotspot security password now required when connecting to USA BM Masters

Hotspots connecting to a BrandMeister Master Server in the USA will now require their users to set a hotspot security password. The configuration change will happen on the following dates:

Master 3101 : November 27th, 2020

Master 3102: December 4th, 2020

Master 3103: December 11th, 2020

Users who already have a password set don’t need to take any action at this time.

For general step by step instructions, you may refer to this post. The link can also be found in the FAQ section of the USA Wiki Page under the Hotspot Configurations section.

UK Master Server 2341 IP change

The UK BrandMeister DMR master has been moved to a new IP address: This is due to unforeseen circumstances that unfortunately did not allow us to provide early notice.

Repeater owners currently pointing to the UK Master 2341 “old IP address” will have to change their repeater configuration. The old IP address might respond to MMDVM protocol but is disconnected from any BrandMeister traffic.

Gateway administrators (OpenBridge, YSF, XLX, WiresX, etc.) need to contact BrandMeister support via the Support Portal or Telegram BM UK Group to re-configure their connection.

Hotspot users please refresh your masters list to ensure the UK Master 2341 is updated with the new IP address The old IP address might respond to MMDVM protocol but is disconnected from any BrandMeister traffic.

Stay safe, and happy QSO !

How to select a BrandMeister Master Server?

One of the main distinguishing feature of BrandMeister DMR is that the network is accessible from any master. Therefore you have a choice of 40+ master servers to connect your repeater or hotspot. How to choose?

The best performance will not always be with the master server that is closest to you geographically. Rather, it depends on your internet service provider’s capacity/peerings and the one of the master server.

The key factors for best DMR performance are jitter, then latency. Below is the most simple method to find the best master for you, without any special software.

Step 1: Go to the Brandmeister DMR Master Servers list, and select which master(s) you want to consider. Click on the “Status” button and grab the IP address for the master in your browser’s address bar.

Step 2: From the same network as your repeater or hotspot, run a “ping” command for 1 to 2 minutes to each master you are considering. Perform this test during the time of the day where your typically have the most traffic.

Step 3: Check that the round-trip delay provided by each ping (called latency) stays consistent, without any major variations (called jitter). See the examples below:

Good (No Jitter):

~ ping -t

Pinging with 32 bytes of data:
Reply from bytes=32 time=71ms TTL=54
Reply from bytes=32 time=73ms TTL=54
Reply from bytes=32 time=69ms TTL=54
Reply from bytes=32 time=68ms TTL=54
Reply from bytes=32 time=71ms TTL=54
Reply from bytes=32 time=74ms TTL=54
Reply from bytes=32 time=70ms TTL=54
Reply from bytes=32 time=69ms TTL=54
Reply from bytes=32 time=69ms TTL=54
Reply from bytes=32 time=68ms TTL=54
Reply from bytes=32 time=69ms TTL=54
Reply from bytes=32 time=69ms TTL=54
Reply from bytes=32 time=70ms TTL=54
Reply from bytes=32 time=72ms TTL=54
Reply from bytes=32 time=70ms TTL=54

You can see that there are no major latency variations.

Bad (Jitter):

~ ping -t

Pinging with 32 bytes of data:
Reply from bytes=32 time=71ms TTL=54
Reply from bytes=32 time=73ms TTL=54
Reply from bytes=32 time=354ms TTL=54
Reply from bytes=32 time=366ms TTL=54
Reply from bytes=32 time=219ms TTL=54
Reply from bytes=32 time=72ms TTL=54
Reply from bytes=32 time=70ms TTL=54
Reply from bytes=32 time=77ms TTL=54
Reply from bytes=32 time=983ms TTL=54
Reply from bytes=32 time=875ms TTL=54
Reply from bytes=32 time=917ms TTL=54
Reply from bytes=32 time=75ms TTL=54
Reply from bytes=32 time=72ms TTL=54
Reply from bytes=32 time=819ms TTL=54
Reply from bytes=32 time=668ms TTL=54

You can observe here the big variances in latency, indicating jitter. Symptoms of jitter include choppy/garbled audio and delayed/dropped transmissions.

Step 4:

Once you have found some masters with no jitter, pick the one offering the lowest latency (smallest ping time).

Using DMR IDs on BrandMeister

The support team noticed a lot of questions are being sent regarding the use of IDs in radios, hotspots and repeater. Here is how BrandMeister recommends to use DMR IDs based on the different use case.

Accessing BrandMeister DMR with your radio and a public repeater or hotspot

All you have to worry about is the codeplug of your radio. In the configuration, you will use the 7-digit DMR ID your call-sign has been assigned (for example: 2060945) and the proper TX/RX frequencies.

Accessing BrandMeister DMR using your radio and personal hotspot

In your radio’s codeplug, configure your 7-digit personal DMR ID as assigned by HamDigital or RadioID. (For example: 2060945).

In your hotspot configuration, use your 7-digit personal DMR ID followed by “01”, for a total of 9-digits. (For example: 206094501). If you have more than one hotspot, use the suffix 02, 03, etc. Always make sure that all your hotspots are using different frequencies.

Do not add only “1”, “2”, etc. for a total of 8 digits, as this won’t work.

You do not need to request a 6-digit repeater ID for a hotspot, even if more than one person is using it, and even if it is dual-timeslot. The 6-digit repeater IDs are designed for large-coverage repeaters.

Providing a BrandMeister DMR repeater for the general public

If you would like to setup a repeater to allow a larger audience to access the BrandMeister DMR network, you will have to apply for a repeater ID with or depending on your geographical location. Use this ID as-is in your repeater codeplug configuration and you are done.

If you are planning to deploy more than one repeater you will need to request a new 6-digit repeater ID for each repeater. Do not add “01”, “02” suffixes in each repeater configuration.

BrandMeister DMR reaches 50,000 Self-Care Accounts

In May 2020, the number of amateur radio operators who have created a Self-Care account on the BrandMeister DMR network has reached 50,000 unique call-signs.

This milestone is a good opportunity to look back at the exponential growth of the network since it started just 4 years ago, and to say thank you to all those who made it happen: developers, users, bloggers, documentation writers, support teams and master admins.

BrandMeister DMR reflectors support ending by end of 2020

The reflectors feature was implemented in the early years of BrandMeister to provide a compatibility with other DMR networks including this functionality and allow reflectors-based hotspots to connect to BrandMeister.

With more and more countries appearing on DMR, the restrictive numbering format of the reflectors (4XXX) is causing talkgroups numbering conflicts for a growing number of countries which MCC code starts with 4.

Our statistics are also showing that less and less operators are using reflectors on BrandMeister DMR, and the demand for new reflectors is practically nonexistent.

For all the above reasons, the reflectors functionality will be retired no later than December 30th, 2020. After this date, Talkgroup 4000 will continue to provide the same auto-static disconnect function and Talkgroup 9 Timeslot 2 will behave just like any other one-digit talkgroup.

If you are using a dv4mini hotspot in reflector mode, please refer to this post to use MMDVM support.

USA 3108 Master Server removal

The USA 3108 Master Server will be removed on or around May 30th, 2020. The 3101, 3102, and 3103 masters have more than enough capacity to take the load.

Anyone with existing bridges connections (CC links, XLX, OpenBridge, etc.) or if you are a repeater owner with a cluster on 3108, please open a ticket on the BrandMeister Support Portal under the BMUSA section and we will get you moved to another master.

New Philippines Master Server 5151

The BM team is delighted to announce a new Master Server 5151 deployed in the Philippines, hosted on the island in the Eastern Telecoms datacenter. With the server physically located in the country, hams from the Philippines and nearby regions can enjoy lower latency, fewer hops, and thus better performance during QSOs.

The server address is at; Fixed IP address at It should already be present in the BM Masters list for all hotspots that auto-update their master server list.

For more information on talkgroup lineup, local BM team, nets, etc. please refer to the wiki page.
