INTRODUCTION
When an LTR trunked radio user wants to communicate with another radio, the user’s radio sends a “channel/talkgroup request” to the home repeater. The system then sends back a “channel/talkgroup grant” to the user’s radio. The channel/talkgroup grant message contains the number of a “go to” repeater to tell the radio which repeater to use. This “go to” repeater can be the same as the radio’s home repeater or another repeater in the system.
The radio uses the “go to” repeater for transmission. Once the transmission has ended, this repeater is available for other users.
