TYT Dmr Software is HERE  


As this is a global network, users need to realise the impact of each talk group on users around the globe as well as nationally and within a region. Time slot 1 is the most busiest with other countries also having other talk groups on this slot so opening a lot of repeaters prevents other network users globally from using the time slot. Ideally the choice of talk group should be as to open the least repeaters possible. As much as some say, activity breeds activity or that the talk group is quiet, note that users may be using another talk group on the same slot that you do not have access to. Its not to limit people from using the facilities on the network but more of having consideration for our fellow amateurs using the network.


Also its worth bearing in mind that not all users have display radios or maybe scanning the talkgroups, so its a good idea to mention which TG youre on as part of your call-in or handover transmission.

TG1, TG2 & TG13

TG1 opens all repeaters globally, TG2 opens all repeaters in Europe and TG13 opens all repeaters in English speaking countries several hundred repeaters can be affected by one of these talk groups. Thus these talk groups are calling channels meant to establish a contact and qsos should be kept limited to a few minutes. Try to prevent UK only qsos on these talk groups by moving to UK Wide user activated talk groups TG80 & TG81 or a more local talk group depending on where the users are located. Other user activated talk groups (TG113, TG119, TG123 & TG129) can also be used to reduce the number of repeaters being opened.


This has a similar impact as TG1, TG2 & TG13 it opens all repeaters within the UK. It prevents other UK users from utilising any other slot 1 talk group. Where possible, users should use the user activated talk groups TG80 & TG81 which are UK only or TG113, TG119, TG123 & TG129 which are World Wide


The new regional layout is the same idea as the original TG8 with the exception that a repeater can have secondary regions added (which would be UA) and that the SE has split into an East & West region. One still needs to look at the number of repeaters being used. Regions vary from 2 repeaters to around 10 repeaters. Its a great facility when mobile travelling around different areas. However many also use it as a general talk group. Many DMR users prefer to use their local repeater in a similar fashion as an analogue repeater with little interest in wide area qsos so using TG8xx prevents them from having a local qso. Other options are the user activated talk groups (TG80, TG81, TG113, TG119, TG123 & TG129) or a special talk group (Special TG8xx) if available on the required repeaters
