+ | ===== What is a DMR ID? ===== | ||
+ | This is a unique identifier assigned to you and your callsign. It is programmed into your radio and transmitted to the network whenever the radio transmits. This ID identifies you on the network. | ||
+ | |||
+ | The DMR ID can be obtained from [[https:// | ||
===== What is a Color Code? ===== | ===== What is a Color Code? ===== | ||
+ | A color code for a DMR repeater is akin to a PL tone for an analog repeater. There 15 color codes (0-15). A radio must be programmed with the correct color code to access the repeater. | ||
+ | This is also useful for telecommunication regulators who have to allocate the same frequency to two DMR licensees in the same region. The regulator simply has to specify a color code in the license conditions - much like PL/DPL was used in analogue as a guard tone. | ||
+ | |||
+ | There is a limitation of course, if two geographically adjacent radio systems use the same frequencies, | ||

===== What is a C-Bridge? ===== | ===== What is a C-Bridge? ===== | ||
- | + | The C-Bridge is the secret to IPSC (Internet Protocol Site Connect) which involves the linking of multiple repeaters to a single network, or to multiple networks. The C-Bridge is also the source of audio feeds of the various audio streams that make DMR what it is. The C-Bridge in essence is part database manager, part master control hub and part gateway. It is responsible for the assignment of what talk groups are available to a particular network; as well as the repeaters attached to that network. | |
- | ===== What is a Code Pluf? ===== | + | ===== What is a Code Plug? ===== |
+ | DMR Radios are configured using “Code Plugs”, which define the repeaters, talk groups, and other settings used by the radio to communicate. Every manufacturer uses their own format, which may or may not be compatible with similar models. Though this model of programming allows a large amount of customization for a given radio, it is also very time intensive – and unlike analog and some digital modes, you must program a DMR radio with a code plug before it will work. | ||
===== Who is DMR-MARC? ===== | ===== Who is DMR-MARC? ===== | ||
+ | MARC stands for Motorola Amateur Radio Club Worldwide Network. It is one of the original DMR network coordinators and is still to this day extremely popular and reliable. | ||
===== Who is BrandMeister ===== | ===== Who is BrandMeister ===== | ||
+ | The Brandmeister Network was born from several worldwide hams and software engineers who joined together to create a digital repeater network consisting of master servers and peer repeaters all over the world. | ||
