- | ==== DMR on RepeaterBook | + | ===== What is a DMR ID? ===== |
- | Repeaterbook.com understands that DMR is a digital format that operates at a bandwidth of 12.5 kHz. DMR can control access | + | This is a unique identifier assigned |
- | DMR incorporates talk groups and the available talk groups are tracked by Repeaterbook.com. They can belong to large networks, which is also tracked by Repeaterbook.com. | + | The DMR ID can be obtained from [[https:// |
- | ===== Allow Admins to Add/Edit Talkgroups | + | ===== What is a Color Code? ===== |
- | Admins will not be allowed | + | 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. |
- | Some repeaters have a tremendous number of talkgroups. Need to build on and expand and collapse function when a repeater has more than 10 talkgroups. | ||
- | The app needs talkgroups | + | ===== 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 | ||
+ | ===== 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. | ||
+ | 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? ===== | ||
+ | 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 ===== | ||
+ | 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. | ||
+ | |||
+ | |||
+ | |||
+ | |||
+ | |||
+ | ===== DMR APIs on RepeaterBook ===== | ||
+ | Repeaterbook.com utilizes two APIs to supplement repeater data. | ||
+ | |||
+ | ==== radioid.net ==== | ||
+ | In order to use DMR through Internet Protocol Site Connect (IPSC) servers, each DMR appliance (radio, repeater, hot spot, etc.) needs to have a DMR ID. For the amateur radio service, these can be obtained through [[https:// | ||
+ | - Repeaterbook queries the repeater call sign and frequency to obtain the DMR ID. | ||
+ | - Repeaterbook queries the DMR ID to obtain the color code and IPSC information. | ||
+ | |||
+ | Radioid.net rules require a registrant to use their own call sign and not the repeaters call sign. In some circumstances, | ||
+ | |||
+ | The API is queried by Repeaterbook whenever a repeater is edited or moderated at the admin level. It is also automatically queried when a new DMR repeater is added to the database. The listed color code, DMR ID, and ISPC Network is gathered and recorded to the repeater' | ||
+ | |||
+ | If there is incorrect data on Repeaterbook which would include the DMR ID or color code, this data can be changed and overridden by a Repeaterbook admin. However, the IPSC is queried directly from radioed.net and written directly to the database. Repeaterbook would encourage repeater managers to update the data on Radioid.net so that Repeaterbook can obtain the correct information. | ||
+ | |||
+ | ==== BrandMeister.info ==== | ||
+ | BrandMeister also hosts the [[https:// | ||
+ | |||
+ | Repeater managers can change the display of the static talkgroups by updating their settings on Brandmeister.network. Repeater owners can also request an admin to update the Repeaterbook list of talkgroup info. Repeater managers may also request to be made a [[custodian|Repeater Record Custodian]] and manage talkgroups on their own (self service). | ||
