- | When editing | + | First of all, you need to understand what a talk group is and why DMR repeaters use them. Talk groups are not just used on DMR repeaters, but also exist on P-25 and other repeater |
- | From this window, you have two options. One is to Add a Network | + | Since DMR repeaters are typically linked to centralized computer hubs, called c-bridges, using talk groups allows repeaters without a user actually monitoring a talk group to remain quiet. An exception is if a repeater has programmed that talk group to be full-time or only activated by PTT. |
+ | |||
+ | So, another caveat to the talk groups is the full-time vs. PTT monitoring. Repeaters have the option of monitoring and repeating all traffic for a talk group all the time. Usually, owners will program a talk group to only be monitored when a user requests it. This can really cut down on the chatter and is a common setting for very large area talk groups, like the Worldwide talk group. For a user to use that channel, they bring up that talk group on their radio and key the radio. This will send a message to the repeater to begin actively monitoring that talk group. This is the same in concept to dialing up an AllStar room, IRLP node, EchoLink node, etc. The repeaters are also set up with a hold off timer which is how long the repeater will listed to that talk group without hearing a local key up. Repeaterbook does not track hold off timers. | ||

+ | The final caveat to a talk group is the time slot the talk group is on. DMR repeaters can actually handle two conversations at once, one on time slot one and one on time slot two. This concept would seem impossible for users of analog repeaters because doubling would occur. However, DMR repeaters can " | ||
