    A Message From Tim Barrett

    2014 was a great year for DMR here in California.  

    At about this time last year, there was just four c-Bridges in our State, less than 20 repeaters on the network and fewer than 200 IDs had been issued to California DMR users.   While those numbers seem small today you could sense there was change in the wind; the CSI radio had just hit the streets and with that the DMR floodgates were thrown open.    

    We’ve seen tremendous growth, currently there are 56 repeaters connected to the California network (with many other major systems in the works) and more than 650 IDs have been issued.  While we’ve been plugging away in Northern California since 2010 a big reason for this past year’s growth has been the work that’s being done by so many others throughout the State.  

    We’ve been fortunate to witness and get to know many of them.  CenCal DMR has worked to cover much of the Central Valley.   In less than 6 months the folks on the SoCal c-Bridge, led by the PAPA System’s organization, have gotten much of Southern California covered.  Closer to home, Baycom has worked their magic, enhancing coverage on the Peninsula, from San Francisco down to Santa Cruz.   

    DMR coverage is fantastic.  According to our coverage prediction software, just shy of 80% of this state’s population can hit a DMR repeater from their home.  Not bad knowing it all began less than 5 years ago!  Better still, is how well the systems all work together.   Without all of the hard work and folks just agreeing to work with one another we could easily have Islands of coverage rather than a single statewide network.

    Which leads to the question, what will we see in 2015?

    I want to share with you that NorCal DMR, PAPA Systems, CenCal DMR and Baycom have agreed to formalize our relationships and together have founded CAL DMR.  CAL DMR is an initiative not an organization, under which we continue to pledge our commitment to work with one another and invite others to join with us.

    Just as we’ve done this past year, CAL DMR members will work on a variety of projects with the ultimate goal of maintaining a robust DMR network made up of individual systems that work seamlessly together.  Specifically:

    • Enable roaming wherever and whenever possible
    • Agree to technical standards yet find ways to support and promote experimentation
    • Identify and align timeslotting on a core set of talkgroups.  
    • Provide support for everyone interested in this mode

    As part of this commitment,
    NorCalDMR.org will take on a new banner.  Effective immediately CALDMR.org will become a central repository for the initiative’s information.  Our hope is that the new site adequately represents the good works of everyone that is part of our community.

    I want to thank everyone for making 2014 a great year in DMR, I have no doubt that through CAL DMR there will be many more.

    73,

    Tim


    About NorCal DMR
    NorCal DMR was established in 2010 with the intent of bringing the latest digital technologies to the Northern California amateur radio community. While still committed to this goal, the organization has expanded its mission. Today the organization works throughout the Golden State to assist others wishing to bring DMR technologies to their communities.

    Just four years after its inception the NorCal DMR Network has grown to more than fifty linked repeaters, located as far south as San Diego, California and as far north as Chico, California. A DMR user can now get almost uninterrupted coverage throughout California's Central Valley, the Northern California coastal regions, the San Francisco Bay Area and much of Southern California. Its repeaters carry 16 standard Talk Groups to connect its users with fellow enthusiasts around the globe.

    The NorCal DMR Network is open to all interested licensed amateur operators wanting to experience the clarity, flexibility and reliability of a digital network.

    To help familiarize users to the new mode the organization has developed the
    NorCal DMR Guide for Best Practices, and makes the Amateur Radio Guide to DMR available here on its website.
