Talk Groups on Time Slot 1[edit]

Talk Groups on Time Slot 2[edit]

User-activated (Tactical) Uruguay Talk Groups on Time Slot 2[edit]

User-activated talk groups, also known as "tactical", "dynamic" or "on demand" talk groups, are activated by pressing PTT once. The talk group will stay active (on the repeater it has been activated) for 10 minutes after the last activation. In Uruguay users "meet" on national or regional talk groups (e.g., TG 748,TS1) and will then agree to switch to one of the user-activated talk groups (TGs 74830, 74840, 74850, 74860). Since user-activated talk groups are used on time slot 2, this operating procedure frees up resources on time slot 1 for other users.

Talkgroup Timeslot Description
