Talk Groups on Time Slot 1


  • 748 - Uruguay national (permanent on most repeaters)



  • 907-JOTA/JOTI (call channel)


  • 9071-JOTA/JOTI (QSO channel)


  • The activation of the JOTA channels is upon request to the repeater's Sysop


  • All BrandMeister talk groups can be activated on any repeater in Uruguay. International talk groups, national and regional talk groups of countries other than Uruguay should be used on time slot 1. Talk group 748 is permanently active on most CX repeaters. It is meant as a calling channel, for establishing the initial contact and facilitate QSY to a regional or user activated talk group (CXUAs). Please remember that QSOs on TG 748 block time slot 1 on almost all CX repeaters.


Talk Groups on Time Slot 2



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


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.

13 9 (12V in) X On GM300 and similar radios, pin 13 connects to J8-5 which supplies +12V switched power from the radio on/off switch.This connection can deliver 500 mA current, fused by the 2A internal radio fuse. Do not forget: jumper 551 on A, jumper 601 on B. (bottom side of radio). This 601 jumper activates/deactivates the audio low pass filter.
