*Naming and allocating of this range of Talk Groups will be done via all Server Owners

Countries – MCC Talk Groups

3 digit up to 5 digits for Main Named Talk Groups. This gives you up to 100 Talk Groups.
example UK 235, 2350 to 23599.  ( * You still have 6 and 7 Dig Talk Groups )

6 Dig ID Talk Groups is normally used by Repeaters
*  7 Dig ID Talk Groups is normally used by End Users, Groups, Clubs etc

Every country has a block of 100 TGs they can use. (MCC to MCC99).
This is to form structure by naming some for users to follow.
Or for bridges.

All Repeaters have 1 TG. Their 6 dig ID (*Not Named)
They could be used for a bridge also and be named if required.

All Users have 1 TG. Their 7 dig ID (*Not Named)
They could be used for a bridge also and be named if required.

Bridges and Naming TGs should be done via the country server owners and when more than one Server in a country by all servers working together.

talk group Naming and allocation

This is done by the Servers in each country.
If more than one server is in your country, you work together.
In the UK we have some rules for ones to follow.

Naming TGs should be kept to a min at all times.
*If you do name a 6 or 7 dig TG for a club or bridge, and it is no longer in use. It is down to you to de-name it.
Also make sure they own that 6 or 7 Dig ID they wish to name.

If you want a 6 or 7 Dig Talk Group named. Speak to @NormanFreeDMR.

WorldWide Talk Groups

This is a list of all Named Talk Groups in use.
Users can also use non named Talk Groups via OPB.
Naming TGs should be kept to a min at all times.

Local talk groups

You can make them local this way.
As only local to your server, they do not get named on the World Wide Talk Group list.

Getting your Talk Groups Listed

Admins can do this now via the online section, or via @NormanFreeDMR.
Users need to speak to Admins for their country.
