BrandMeister DMR operating: practical examples

Posted in DMR

The BrandMeister network offers many possibilities for operating in DMR (Digital Mobile Radio). Operating in DMR is easy:

  • select your repeater and operating timeslot,
  • select your talkgroup,
  • press PTT and talk.

Before talking, there is no need to check the network status or to link the repeater to reflectors or modules with complicated key presses.

Here are some practical examples for Luxembourg (as of 2018/01/01):

LOCAL CALL on a repeater: TG 9

If you wish to operate locally on a certain repeater you can reach, use the talkgroup 9 (TG 9) on timeslot 1 (TS 1). Your signal is only repeated on the selected repeater on timeslot 1 (TS 1) and operators monitoring the repeater should hear you.

Example:

The example shows a ham working on the repeater LX0DMR. He uses the talkgroup 9 (TG 9) on timeslot 1 (TS1) because he wants to operate locally on a repeater and hams are normally monitoring timeslot 1 (TS 1) of repeaters.

LX CALL on a repeater: TG 270

If you wish to operate nationally via all the DMR repeaters in LX connected to the BrandMeister-network, make your call on any repeater connected to the network. Use timeslot 1 (TS 1) and the talkgroup 270 (TG 270). Your signal is repeated via all the DMR repeaters in LX and operators monitoring any repeater in LX should hear you.

Example:

The example shows a ham working on the repeater LX0DMR. He uses the talkgroup 270 (TG 270) on timeslot 1 (TS1) because that talkgroup is static on timeslot 1 (TS 1) of any DMR repeater in LX.

His signal is repeated

  • via all DMR repeaters in LX on timeslot 1 (TS 1): LX0DMR, LX0DMX, LX0DRR, LX0NSR, LX0RU,
  • via hotspots monitoring the talkgroup 270 (TG 270),
  • via foreign repeaters where the talkgroup 270 (TG 270) was activated dynamically.

If the ham had worked by error on timeslot 2 (TS 2) of LX0DMR, his signal would nevertheless have been repeated

  • via all DMR repeaters in LX on timeslot 1 (TS 1): LX0DMR (both timeslots busy), LX0DMX, LX0DRR, LX0NSR, LX0RU,
  • via hotspots monitoring the talkgroup 270 (TG 270),
  • via foreign repeaters where the talkgroup 270 (TG 270) was activated dynamically.

CALL FROM ABROAD to LX: TG 270

If you wish to make contact to LX, make your call on any repeater connected to the BrandMeister-network. Use timeslot 2 (TS 2, check the recommendations abroad) and the talkgroup 270 (TG 270). Your signal is repeated via all the DMR repeaters in LX and operators monitoring any repeater in LX should hear you.

Example:

The example shows a ham in Belgium near Oostende working on the repeater ON0OST. He uses the talkgroup 270 (TG 270) on timeslot 2 (TS 2) because that talkgroup is not static on repeaters in Belgium so it can be linked dynamically which should be done preferentially on timeslot 2 (TS 2). The dynamically linked talkgroup remains active for 15 minutes after the last PTT press of the ham on ON0OST using the talkgroup 270 (TG 270).

His signal is repeated

  • via the local repeater on timeslot 2 (TS 2), in this case ON0OST,
  • via all DMR repeaters in LX on timeslot 1 (TS 1): LX0DMR, LX0DMX, LX0DRR, LX0NSR, LX0RU,
  • via hotspots monitoring the talkgroup 270 (TG 270),
  • via foreign repeaters where the talkgroup 270 (TG 270) was activated dynamically.

If the ham had worked by error on timeslot 1 (TS 1) of ON0OST, his signal would nevertheless have been transmitted to the talkgroup 270 (TG 270).

LX LARU CALL on a repeater: TG 2707

The LARU is the only operator of DMR-mono-mode repeaters in LX. The advantage of these repeaters is, that they are not mixed or multi mode and DMR is the only mode available permanently so that other modes cannot take over the repeater and disrupt your attempt to communicate.

If you wish to transmit via the repeaters operated by the LARU, make your call on any LARU repeater Using timeslot 1 (TS 1) and the talkgroup 2707 (TG 2707). Your signal is repeated via all the LARU DMR repeaters in LX and operators monitoring any of these repeaters in LX should hear you.

Example:

The example shows a ham near Ettelbrück working on the repeater LX0NSR. He uses the talkgroup 2707 (TG 2707) on timeslot 1 (TS 1) because that talkgroup is static on LARU repeaters.

His signal is repeated

  • via all LARU DMR repeaters in LX on timeslot 1 (TS 1): LX0DMR, LX0DMX, LX0NSR
  • via hotspots monitoring the talkgroup 2707 (TG 2707),
  • via foreign repeaters where the talkgroup 2707 (TG 2707) was activated dynamically.

If the ham had worked by error on timeslot 2 (TS 2) of LX0NSR, his signal would nevertheless have been repeated

  • via all LARU DMR repeaters in LX on timeslot 1 (TS 1): LX0DMR, LX0DMX, LX0NSR (both timeslots busy),
  • via hotspots monitoring the talkgroup 2707 (TG 2707),
  • via foreign repeaters where the talkgroup 2707 (TG 2707) was activated dynamically.

CALL to Saarland / Rheinland-Pfalz on a repeater: TG 2625

If you wish to contact foreign repeaters via an LX repeater, make your call on any repeater using timeslot 2 (TS 2) and the corresponding foreign talkgroup. Your signal is repeated via your local repeater and all the foreign repeaters where the used talkgroup is active. Operators monitoring any of these repeaters should hear you.

Example:

The example shows a ham near Luxembourg-City working on the repeater LX0DMR. He uses the talkgroup 2625 (TG 2625) on timeslot 2 (TS 2) because that talkgroup is not static on repeaters in Luxembourg so it can be linked dynamically which should be done preferentially on timeslot 2 (TS 2). The dynamically linked talkgroup remains active for 15 minutes after the  last PTT press of the ham on LX0DMR using the talkgroup 2625 (TG 2625).

His signal is repeated

  • via the local repeater on timeslot 2 (TS 2), in this case LX0DMR,
  • via german repeaters in Saarland and Rheinland-Pfalz, where the talkgroup 2625 (TG 2625) is static.
  • via hotspots monitoring the talkgroup 2625 (TG 2625),
  • via any repeater where the talkgroup 2625 (TG 2625) was activated dynamically.

If the ham had worked by error on timeslot 1 (TS 1) of LX0DMR, his signal would nevertheless have been transmitted to the talkgroup 2625 (TG 2625).

 

 


BrandMeister settings for LX

Posted in DMR

The DVC working group recommends the following settings for operating in the BrandMeister network  in Luxembourg:

Selfcare:

You should create a BrandMeister network account, for adjusting personal settings. Adjust the following settings in Selfcare:

  • APRS SSID 5
  • Select an icon.
  • Select your radio brand (transcoding of messages).
  • Put your first name in the APRS text field.

Talkgroups:

The following static talkgroups are present on LARU repeaters (these talkgroups are present permanently):

Timeslot 1 (TS1) Timeslot 2 (TS2)
TG 270 Luxemburg TG 9 local
TG 2707 LX LARU  
TG 9 local reflectors

Depending on the location of the repeater, additional static talkgroups are present on timeslot 1 (TS1):

Timeslot 1 (TS1) Repeater
TG 2701 LX South LX0DMX
TG 2702 LX North LX0NSR
TG 2703 LX Center LX0DMR

Dynamic talkgroups can be activated on both timeslots in the BrandMeister network. This makes it possible to activate all existing talkgroups temporarily on a certain timeslot (e.g TG 262, Germany). Existing talkgroups can be looked up here. Aktivated talkgrups will be automatically unlinked after 15 miutes of inactivity.

The LARU recommends:

  • Timeslot 1 (TS 1) for national QSO's (TG 270, TG270x and TG 9)
  • Timeslot 2 (TS 2) for international (dynamic talkgroups) and national QSO's (TG 9).

Dynamic talkgroups

  • should be activated preferentially on timeslot 2 (TS 2).
  • If a timeslot is busy, the other one can be used.

Reflectors

Reflectors exist on timeslot 2 (TS 2). These are present for backwards compatibility with other networks. A permanent reflector should not be linked on timeslot 2 (TS 2)

These recommendations allow a parallel operation of national and international calls on the repeater. Please send questions to the DVC working group: This email address is being protected from spambots. You need JavaScript enabled to view it.
