+ | ===== 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. | ||
===== What is a Talkgroup? ===== | ===== What is a Talkgroup? ===== | ||
+ | DMR repeaters and networks incorporate a system of “talk groups.” These are simply an ID code transmitted by the radio, that is accepted by the repeater, and retransmitted to other DMR radios on the same channel, and potentially across the Internet to other linked systems. This ID code is a simple number like “310.” In the DMR world, 310 has been given the moniker of “Tac-310.” Any radio that is set to receive Tac-310 on that repeater’s frequency channel will open the speaker and allow the transmission to pass to the end user. Any other radio not monitoring Tac-310 will remain silent. These talk groups are programmed into radios like channels. A repeater could support multiple talk groups and the end-user radio would have to have each of these talk groups programmed into separate memory channels in order to utilize them. Memory slot one could be Tac-310, memory two could be Tac-311, and memory three could be Tac-312, for example. The repeater’s frequency and access codes could all be the same with the only difference being the talk group code. It is important to know which time slot the talk group is on, as that must match. Repeaterbook tracks the talk groups available to a repeater. | ||
===== What is a C-Bridge? ===== | ===== What is a C-Bridge? ===== | ||
+ | There are technically two different uses for a c-bridge. The first one is at the local level to cluster, or connect, upto 15 repeaters into a hub. Repeaterbook simply refers to these as IPSC networks. | ||
- | ===== What is a Code Pluf? ===== | + | The second use to connect clusters of repeaters to additional clusters of repeaters. Repeaterbook tracks this bridge assignment, when known. The cBridge is also the source of audio feeds of the various audio streams that make DMR what it is. The cBridge 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 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. | ||

Repeater owners can also request an admin to update the Repeaterbook list of talkgroup info.
