DMR - Digital Mobile Radio

Presented by

Bob Molczan, KA7VPR


Digital Mobile Radio (DMR) has been available for use by Radio Amateurs for several years, although out of reach for many due to the high cost of equipment only available from the commercial radio market.  Within the last 3 years an influx of affordable DMR radios for the Amateur market has made DMR available to everyone at costs remarkably less that current market analog/digital equipment from leading HAM radio manufacturers.

DMR is a very efficient Digital Voice mode with High Quality Audio and Superior RF Signal propagation characteristics.  DMR repeaters are linked world wide, and the availability of two DMR networks, Motorola and Brandmeister offer options to both the Experimenter and the Casual operator.  DMR Repeater and Hot Spot building is available and adds to the fun and effectiveness of DMR.

However, DMR has been given a "Bad Reputation" as being "Hard or Impossible" to program when it comes to developing a profile or "Code Plug" for one's radio.  For this reason many have either given up on or shied away from DMR to seek ease of operation from other digital voice modes.  This misconception of DMR's "lack of user friendliness" makes it difficult for Multi-Mode repeater groups like OVARC to justify keeping the DMR mode active on our area repeaters.

My presentation will attempt to dispel all of the misconceptions about programming DMR radios, and provide a clear explanation of how to write a "Code Plug". Details pertaining to DMR terminology and different "Customer Programming Software" (CPS) will be provided, along with samples of code plugs and much more.

I personally have been using DMR for over 5 years now, and own both commercial and amateur DMR radio gear from companies like Motorola, Vertex, CSI, and Anytone.  Although I do not claim to be an expert on DMR, I believe that I can remove many of the obstacles that keep you from making DMR your "Go To" mode for Digital Voice communications.  Please join me at the next OVARC General Session club meeting in October.
