South-Korea Master 4501 back on-line

The South-Korean Master server is back on-line. Unfortunately the local administrators were not able to recover the configuration from the crashed drives. If you are a repeater owner and connect to Master 4501, you will have to re-configure the following: Static Talkgroups, Timed Subscription, Reflectors, Cluster membership, and custom repeater passwords (ask local administrators or BM Support).

We apologize for the downtime and the inconvenience, and wish you happy QSOs now !

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.

How to proceed ?

First, create a personalized password in your BrandMeister selfcare.

1. Login to your BrandMeister Selfcare

2. On the top right, click on your Callsign

Click on your callsign

3. Click on the “SelfCare” option

Select SelfCare

4. At the bottom of the page, check the box “Hotspot Security”

Select HotSpot Security

5. A password box will appear. Enter your personalized hotspot password and click “Save”.

Enter a hotspot security password

Setup the password on your hotspot

OpenSpot

1. Login to yourOpenSpot web interface , and click on the “Connectors” option

2. Make sure your Active Connector is “Homebrew/MMDVM”. (If not, select it from the “Edit connector” dropdown, and click ” Switch to selected”

3. Scroll down to the “DMR/Homebrew/MMDVM” section. The current “Server Password” is the generic one for the master you are currently connected to. Change this field to your customized password.

4. Click the “Save” button

pi-Star (Raspberry-based hotspots such as JumboSpot, Zumspot, etc.)

  1. Login to your pi-Star web interface, and click on the configuration page.

2. Scroll down to the “DMR Configuration” section, and input your hotspot password in the “Hotspot Security” field

3. Click on the “Apply Changes” button below the field.

Note that if the field Hotspot Security is empty, it will revert to using the default password from the DMR Host file provided with pi-Star updates.

It’s BrandMeister DMR 3rd Birthday !

Happy Birthday BrandMeister DMR !

Three years ago, after eleven months of intense tests and development, a new software emerged in the amateur radio DMR realm with features never seen before. New master servers appeared quickly in many countries, thus creating the BrandMeister DMR Network. Sysops connected their repeaters to the network to enjoy the features, and digital ham operators over the world quickly adopted the new platform for their DMR transmissions.

BrandMeister quickly included inter-connectivity allowing international operators using mixed digital and analog technologies to have QSOs together (D-STAR, C4FM, NXDN, Analog).

Today, as we are celebrating BrandMeister DMR’s 3rd birthday: the network is counting 44 master servers installed across the world, 2600 repeaters and 7800 hotspots are connected and an average of 30 concurrent calls are taking place at all times !

This birthday is an opportunity to acknowledge all the volunteers who contributed in the success of BrandMeister by spending countless hours in programming, setting up servers and hosting platforms, testing, translating, documenting, and providing users and sysops support. BrandMeister also received donations which contributed to the implementation of new features and new hardware support on the servers. Thank you to everyone for your contribution ! 

In just one year of time, several major features have been added to BrandMeister, such as:

This coming year, you can continue to expect a lot of new things! Stay tuned for news about optimizations, Open DMR Terminal Protocol, Wires-X, APIs and more!

 

Talkgroup traffic exchange between BrandMeister Master and IPSC2 servers

A couple of months ago Artem/Brandmeister and Kurt/IPSC2 have worked together to create a new protocol to interconnect BrandMeister Master Servers and IPSC2 servers, for the purpose of exchanging TalkGoup traffic: OpenBridge.

Since version 20180610,  BrandMeister master servers can be interconnected with IPSC2 servers to exchange talkgroup content. Talkgroup numbers are configured on both sides, and traffic goes both ways with the ability to have traffic on multiple TalkGroups at the same time.

While you can check for the presence of an OpenBridge connection on a BrandMeister master’s status page, the protocol does not include any connection-establishment, nor keep-alive.

If you have an IPSC2 server and would like to interconnect it with the BrandMeister network, please contact the BrandMeister Master Server of your country (or the closest one if there are none in your country) to request the connection.

LastHeard Back-end Redesign

The BrandMeister database back-end for the last-heard application has been completely redesigned, bringing more speed and storage.  You can now enjoy a much more responsive last-heard with 30 rows history, and a near-instant call statistics and contact export !

The last-heard back-end is now powered by MongoDB: 3 configuration servers, 2 query servers, and 4 shards !

We want to sincerely thank Daniel – YO5DSG and Cafe Gratis Sports Club – YO5KFG for their contribution of all resources involved in this new backend platform.

 

BrandMeister DMR supports the new Hytera PDC-760 LTE/3G/Wifi radio & cell-phone device !

Hytera PDC-760

This new Hytera radio combines a conventional Analog FM radio, a DMR Tier I+II+III radio, and a cell phone !

The PDC-760 can connect to the BrandMeister DMR network over the air (repeater or hotspot) and over an IP network (WiFi , cellular 3G and LTE ).

This IP67 dust and waterproof radio is running an android operating system, a color 800×480 gloves-compatible touch screen with shatter-resistant Gorilla® Glass 3, and features a 128×96 top LCD display for easy reading from above.

You can configure Talkgroups from the front screen or the codeplug.

When using an IP network, you can connect to the BrandMeister DMR network and use Talkgroups, Private call, and Private messages as you would normally over the air or with a hotspot. Two BM modes are available:

  • Automatic: incoming traffic for talkgroups, private calls and sms messages.
  • Exclusive: once you select a private or group contact and push PTT, you will be placed in an exclusive mode where no one else can disturb you. You can press the hang up button to exit. It’s like having a private half-duplex phone call !

This new radio includes Hytera’s latest smart battery fast charge technology, 3 times faster than regular batteries allowing an 80% charge within 30 minutes. Full charges can be achieved in 1 hour !

The BrandMeister master servers running version 20180601 and above support this device. Below is a video clip of the device connected to a BrandMeister network over IP:

Notes: BrandMeister does not support video calls nor phone calls (PSTN). The switch between over-the-air and over-ip is done manually by the user.
