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 ? 

We are running out of ID for DMR

Getting a lot of questions around why we are issuing 3100nnn for USA and 3020nnn for Canada instead of the State/Provincial specific ID's. There are a few simple reasons.

  • We are running out of ID's, the old way of assigning ID's by state/prov isn't working
  • Many states/provs have already reach nnnn999, There is no where else for them togo
  • MCC numbering scheme was never designed for states/provs, This was a 'nice to have' made up system
  • Brandmeister as of May 1st has decided to no longer route 1nnn MCC ID's

Fortunately the only real solution was to go to the base sequence of the country and start assigning the ID's sequentially. We have started with CAN and USA, but all countries will shortly follow, This solution has been implemented in the EU regions for some time. This is still only a short term solution, we will still eventually run out of ID's as there is finite list that will function with our system.

DIgital Amateur Radio FCS network explained

I'm new to all of this, and after searching, I'm having difficulty understanding the FCS network and how it al works.

I've been on the x reflector website, but it doesn't seem very intuitive or have much of a description, that I found, anyway.

Are there any resources that explain the system better? YouTube videos? Even basic info like, are the reflectors tied into local repeaters. Like IRLP or Echolink? Or are they just "chat rooms" for digital modes?

The Explosion of Digital and why it is growing

This subject of digital as in DMR is an Exploding system compared to anything in HAM Radio, bar none, and has been for many years as a dynamic mode that is often changing.   A mode that is challenging the HAM radio community's user base as it evolves. This compared to the stagnant water of any "anything" or mode in HAM Radio.

A network from it's inception that offered a single manufacture and commercial (public service) grade devices is now offering numerous manufactures, important to note that no other HAM Radio mode offers as many devices to select from in purchasing. The on "fire" prices are beneficial to the consumer as value for money, as found in the many affordable devices that are offered in Digital Mobile Radio. The cost of DMR device almost comparing and rival inferior FM analog transceivers.

Benefits include:  device firmware exploits from Travis to Ty all to the benefit of the end user or ham radio operator.  With dismal advances in any other aspect of the radio hobby this is welcome change and may stimulate old bones in other areas of the hobby.

To the surprise and joy of many in the DMR community the introduction of Hotspots and its popularity continue to evolve and explode the digital user base, with the ability to shift users moving to self empowered devices and also have the option to use the many repeaters as backup if available for communication tools.

Now, to the joy and relief of most digital users we have the flexibility of moving off a repeater that most often is or could be abusive by an inept individuals with a CB mentality.

DMR MARC network to be taken offline permanently in Germany

I regret the fact, that the DMR MARC network in Germany will be taken offline permanently on July 31st, 2017 according to the official website (german):

The German DMR MARC team will cease operation of the DMR-DL server as of July 31,  We would like to thank all the sysops and users of the network for the long-term trust.
Das deutsche DMR MARC Team wird zum 31. Juli 2017 den Betrieb des DMR-DL Servers einstellen.   Wir danken allen Sysops und Nutzern des Netzes für das langjährige Vertrauen.

At this point time, we don't know about the availability of a permanent or temporary solution during the net (Saturdays 1600–1730 UTC DST / 1700–1830 UTC) for the access to WW 1 on DMR-MARC via crosslinks from other networks.

The Amateur Radio Digital Wars

The Amateur Radio Digital Wars

Top 3 Ham digitals ::
- ICOM - DStar
- Yaesu - Fusion aka C4FM
- DMR (digital mobile radio aka Mototrbo) - many companies producing transceivers - DMR :fragments: BrandMeister, DMRplus, Mototrbo/MARC
** Excluded :  NXDN, pDmr, P25, ect.


Interconnection :  when talking about all of the digitals, none communicate with each other.  A basic understanding is none of the different digitals talk together.

Frequency :  All digitals use Amateur Radio frequencies same as Analog FM - VHF or UHF frequency band, in handheld/portable or mobile or base configuration

Cost saving :  only one of the three digital has many many companies producing Transceiver. The other two * only have (1) one producer of transceivers.  The cost of a DMR transceiver abt. $100 or a fifth to the other two digitals of about $500 per transceiver

Most popular :  the first to market digital was DStar and since is the largest in the market, however with  DMR manufacturers offering a large selection of affordable transceiver.   DMR has grown in the market of multiples of 10x year over year.   The third digital is Yaesu and has very slow growth.

Summary : they are all interesting , however DMR is the clear winner.

DMR-MARC and DMR Plus partnership (DMR Plus North America)

DMR Plus is the original network that developed tools to interconnect Hytera and Motorola repeaters. It has been popular in Europe for years but now, with the cooperation of DMR-MARC, it has finally arrived in North America and the South Pacific. The DMR Plus architecture is similar to D-Star. Users have talkgroups to converse, to disconnect, and to monitor channel status. Users choose from a large pool of reflectors and move back to the converse talkgroup for all QSOs.

The DMR-MARC and DMR Plus partnership is ideal. The DMR-MARC network is robust and reliable. The DMR Plus network is more aligned with experimentation and interoperability of technologies. Think of DMR Plus as the best possible implementation of the former DMR-MARC Sandbox.
