GPS 5057 destination

On the 1st of march we will phase out the GPS destination 5057. If this is the destination ID you are currently using in your codeplug, please update it as soon as possible using the instructions below.

You will need to replace the GPS destination with the first 3 digits of any active BrandMeister Master Server ID (ie: 204 for Netherlands, 208 for France, 310 for USA, etc.) followed by 999. For example the following destinations are valid for GPS destinations: 204999 (because there are masters 2041 and 2042), 208999 (because there is a 2082 master), 310999 (because there are masters 3101,3012, 3103, 3108), etc.

The first 3 digits of the GPS destination does not have to match those of the BrandMeister master server where your repeater or hotspot is connected to. For example, you can use GPS destination ID 208999 even if the repeater you use is connected to master 2042.

How to choose the GPS destination ID for your codeplug ? If the country where you operate has a BrandMeister server, the most logical choice is to use the first 3 digit of your country’s master ID and add 999 (for example 262999 if you are in Germany). If your country doesn’t have a master server, use the first digits of the one closest from your location.

Last Heard status

Update (11:24 UTC): All services report up and running.
The cause of the outage was a problem while migrating one of the 4 lastheard storage servers to there new datastore. The machine is recovered and back in to service.

Update (10:12 UTC): The broken machine is back online and the LH is recovering.

Currently we are experiencing some issues with the storage backends of the lastheard this means that history searches don’t work and also graphs using data from the history will have some issues.

We are working on a solution bare with us

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.

Support for NXDN reflectors and NXCore

Support for NXDN (NX-REF and NXCORE) has been added in the latest version of BrandMeister DMR Master Server.  Master server administrators can assist you in setting up a gateway.

Here are important considerations to know about the NXDN implementation.

NXDN protocol

Keep in mind that unlike DMR, the ID numbers on NXDN are limited to a 16-bit value.  Everything above 65519 will not be recognized.

BrandMeister Server

BrandMeister does not do any ID translation between DMR<->NXDN :

*  When you receive NXDN traffic on BrandMeister, the original NXDN IDs will be showing up as the source and the talkgroup.

* When you transmit on a BrandMeister talkgroup that is bridged with NXDN, only the last 16-bits of your DMR ID will be kept and used as a the source on the NXDN network.

There is also no translation between the two systems Talkgroup IDs. Only Talkgroup numbers between 91 and 65519 are supported.

BrandMeister currently only supports the ICOM implementation of NXDN.

BrandMeister has implemented private calling support for NXDN, but at this point neither NX-REF or NXCORE have implemented this feature on their end.

NXCORE

NXCORE only supports 1 concurrent call (half duplex). This means that if several people are transmitting on a talkgroup connected to an NXcore, only one transmission will go through, and all others will be discarded until the gateway path becomes available.

You will not be able to setup multiple NXCORE on the same server to the same BrandMeister master server (by using different port numbers for example). NXCORE recognizes a BrandMeister master server as a repeater; and NXCORE identify repeaters by IP only (not by ID, not by IP/PORT).

Using correctly formatted user MCC ID on BrandMeister

As DMR made its debut in Amateur Radio, hams had to figure out which numerical identifier to use when programming DMR radios since there was no way to use alphanumerical callsigns. It was decided to use 7-digit numbers to identify radio operators; and to setup a public on-line database that provides the correspondance between the IDentifier and the amateur radio callsign.

It was further decided that the first 3 digits of the IDentifier would follow the Mobile Country Code numbering as defined in the ITU-T Recommendation E.212. This first 3 digits of the ID you are entering in your DMR radio are therefore identifying your geographical origin :

1 – Test networks
2 – Europe
3 – North America and the Caribbean
4 – Asia and the Middle East
5 – Oceania
6 – Africa
7 – South and Central America
9 – World-wide

BrandMeister is based on open-standards, which is a critical aspect of the network as it is open to third-party developers. It is therefore critical to stay consistent and follow standards.

We have noticed some users operating on the BrandMeister network with IDentifiers starting with the number 1 (example 1118001, a station in Indiana, USA). These numbers do not follow the MCC numbering standard and therefore it causes issues and confusion in third party systems with region-specific features.

Two organizations exist for issuance of DMR ID’s, DMR-MARC and Ham-Digital. Once it was realized that DMR-MARC started issuing IDentifiers outside the already agreed upon MCC numbering standard, administrators and system operators with the BrandMeister network reached out to the leadership with DMR-MARC to come to a viable solution that would rectify this issue and retain the MCC numbering standard. That was nearly 2 years ago. Since then, dozens of attempts were made to reach out to leadership with DMR-MARC to come to a solution to this issue, but those organizations will not communicate back with us regarding this. They have ignored every single attempt BrandMeister leadership has made to them.

While we have left the 1XX IDentifiers operating on the BrandMeister network temporarily, the unfortunate result, because of the lack of communication and cooperation from the organizations in charge of issuing ID’s, will be the restriction of importing NEW 1XX numbers starting May 1st, 2018.

So, what does this mean:  Beginning May 1st, 2018, BrandMeister will stop importing new 1XXYYYY USA ID’s from DMR-MARC. All existing ID’s will continue functioning, meaning if you were issued an ID in the 1XXYYYY format (example 1118001), your ID will continue to work. Any new USA ID’s issued in this format after May 1st will no longer. If you are issued a DMR identifier after May 1st, 2018 that doesn’t follow the MCC numbering standard (i.e. starting with 1XXYYYY) and want to use the BrandMeister DMR network, please make sure to request a correct ID before this deadline.

We truly realize the monumental impact this decision brings to the various BrandMeister sub-networks as well as all the users of BrandMeister this has the potential to affect. Rest assured, we are not giving up, and will continue to reach out to the DMR-MARC leadership before the May 1st cutoff to try and come to a cooperative solution. We encourage you as well, the users, repeater trustees, network administrators, system operators, etc. to reach out to both DMR-MARC and encourage them to have a productive conversation with the BrandMeister admins. Only through cooperation and collaboration will there be a resolution.

Some statistics about unique IDs using BrandMeister and selfcare accounts

We ran database query over the past 6 months and have seen that more than 54,000 unique DMR IDs have been utilizing the BrandMeister network. That’s more than half the number of IDs assigned by DMR-Marc !

As of today, 16,000 unique users have created a Self-Care BrandMeister account . (per call-sign; some call-signs might have several DMR IDs)

Thank you all for your continuous support for the BrandMeister DMR network!
