The Global DMR Contacts is just that, a database of every DMR ID and the information of the person that applied for it.
The Global DMR Contacts is just that, a database of every DMR ID and the information of the person that applied for it.
In 2010 all the big DMR companies got together and decided to standardize/share their contacts as you would have someone on Brandmeister complaining that someone on DMR+ hijacked their DMR ID.
You can run your radio without the global contacts but it is really nice to have a radio that can hold them all so when you are talking to someone you can see their callsign, name, location right there on your screen. (if your radio has a screen.)
