A DMR Presentation

My name is Andre from Canada, I was tasked to offer my subjective comments about digital and the relation Digital Mobile Radio (DMR) aka MotoTrbo as it compares. An overview of DMR and how it’s being adopted by hams all over the world, including a live demonstration of world wide communications using DMR.

The presentation discussed the popularity of digital and the choices to select from ; ICOM-DStar, DMR(many), Yaesu Fusion C4FM, Kenwood/Icom NXDN NexEdge, APCO P25 to name but a few. Digital are not compatible with other digitals. Different digital company do not connects/talks together.

The lasting comments to the subject we had as a group.
The decision we may have to make when considering v/uhf digital is the availability of repeater(s) for that digital.http://dmr-marc.net/repeaters.html

Digital Mobile Radio (DMR) aka MotoTrbo and many (20+) handheld or mobile models.
  • DMR-MARC - Digital Mobile Radio-Motorola Amateur Radio Club is a network with only Motorola repeaters linked
  • Brandmeister - started as European network now a growing network of multi model repeaters (Motorola, Hytera, etc) and hotspots
  • DMR+ has almost no following in the US. The primary users of that network now are almost all in Europe.

Some of the notable recent DMR models coming as of March 2017 are the following : Connect System CS580(Frequency scan), Tytera MD2017 duel-band Handheld DMR, Tytera mobile MD9600, DV4home/DV4Mobile (all modes into one radio DStar/Fusion/DMR)

The growth for that digital or adoption rate, possibly considering why the increase by many consumers around the globe that may have adopted.

To filter down in the subject of DMR and the system configuration file known as a codeplug. Considering when making a buying decisions a popular radio model as to have many friends or users to share that codeplug, why important so you may not have to spend many hours creating a new configuration file that might be freely and publicly shared. Each transceiver stores 1000 list ie.telephone-book know as a Contact-List with DMR user call signs that need to be updated often as new DMR users register.

The DMR official page that shows the map of repeaters, the website to request a new User identification for DMR as a 7 digit number known as CCS7. http://dmr-marc.net
