DMR usage

There are two basic types of DMR calls: private and group.

Important

Talkgroups and reflectors are network features, they are completely handled by the network and not the M1KE, and their behavior may be different on each server / network.

Talkgroups

DMR networks usually have static or dynamic linking available for a talkgroup. Statically linked TGs remain linked all the time, dynamically linked TGs stay linked for you only for a limited amount of time after the last call (usually 15 minutes on BrandMeister, depending on the currently used server’s configuration).

Having a talkgroup linked either dynamically or statically means that stations which have the same linked talkgroup will receive all (usually group) calls sent to that talkgroup.

Example: if you have TG969 linked either dynamically or statically, then the server will forward group calls (coming from other stations) going to DMR ID 969 to your M1KE and you will hear them.

Dynamic talkgroups

Note

The following information is only valid for the BrandMeister Network. Other networks may behave differently.

Linking

You can link a TG dynamically by simply starting a (group) call to the talkgroup ID. The network will automatically link your M1KE to the called TG ID.

Note

You can use also the Quick Call feature on the web interface or on the device display to link talkgroups.

If the Auto group call setting is enabled at the Quick Call settings, the device will automatically start a quick call to TG4000 before quick calling the desired ID. This ensures that all previously dynamically linked talkgroups are unlinked by the server first.

Unlinking

To unlink all dynamically linked talkgroups, call TG4000 (start a short group call to DMR ID 4000).

Note

Calling TG4000 will also unlink linked reflectors, not just all dynamic talkgroups.

Auto static talkgroups

There’s BrandMeister Network feature called auto static talkgroups: the first talkgroup ID you call after calling TG4000 will be linked auto static which means it won’t be unlinked after a timeout. You can unlink this auto static TG by calling TG4000.

Static talkgroups

Static talkgroups on the BrandMeister Network

Statically linked TGs can be configured on the BrandMeister Network’s dashboard after logging in, or by using the M1KE’s BrandMeister Manager.

Static talkgroups on DMRplus/IPSC/other networks

You can define what TGs to link statically at the DMRplus options section at the bottom of the Homebrew/MMDVM® connector, or use the server’s/network’s dashboard (if available).

Reflectors

Reflector IDs are between DMR ID 4000 and 5000. To link a reflector, start a short private call to the reflector ID. To unlink the reflector, start a short private call to DMR ID 4000.

Only 1 reflector can be linked at a time. To talk on the linked reflector, send your calls to DMR ID 9 with a group call (TG9). You’ll receive all calls from the reflector also to TG9.

Important

Reflectors have been turned off on the BrandMeister Network since 2020. Most servers already have them disabled. Use talkgroups instead.

Recommendations

BrandMeister Network

Avoid statically linking talkgroups and only use one auto static talkgroup at a time.

DMRplus/IPSC/other networks

Define what TGs to link statically at the DMRplus options section at the bottom of the Homebrew/MMDVM® connector.

Changing modules on XLX servers

To unlink the currently linked module, call DMR ID 4000. To connect to module A, call DMR ID 4001, for module B call DMR ID 4002 and so on.
