Talk Groups can be viewed like a telephone exchange, directing your “call” to different areas. There are over 100 talk group available around the world – most are based on time slot 1. Some are based on geographical location or language thus not all talk groups are available in every country.
If you refer to the “Best Practice” guide under the Talk Groups menu, there is a drive to reduce resource usage thus choice of talk group is vital. This is also important due to the number of talk groups on slot 1 thus several “wide area” talk group should be considered as calling channels. This is both to reduce the number of repeaters “locked out” by your QSO but also to prevent stopping other users from utilising slot 1.
Note that on a single repeater, each time slot can only Tx / Rx one talk group at a time.
TG9 on both slot (primary and secondary) are the same as using an analogue repeater
These are specific to a countries regions. In the UK we have several regions based on a similar scheme to the ETCC regions. The North is split into North West and North East. The SE England / London Region also being split into Metro East & West. These allow for the use of the roaming function whilst travelling around your area.
These are requested by a group of Keepers to link their repeaters for many reasons. In Weston Super Mare, a special link connects their UHF and VHF repeater allowing local users on both bands to have a natter. Only linked repeaters have their talk group as active so users from other areas can not link in.
User Activated TG’s
These you can’t hear unless you activate them by pressing the PTT. These only affect repeaters that have them activated thus are a good alternative to the wide area talk groups. Currently there are 2 World Wide (TG119 & TG129), 2 English WW (TG113 & TG123) and 5 UK Wide (TG80, TG81, TG82, TG83 & TG84) UA talk groups. Please review the UA TG guide under the Talk Group menu for more information.
Wide Area TG’s
These include the world wide (TG1, TG2 & TG13) and national talk groups (TG235) which link us with fellow amateurs around the country or around the world. These are considered as calling channels and should be used for brief qso’s in order to establish a contact then qsy to one of the User Activated Talk Groups
