DMR transceiver

(only shown if
Advanced mode is enabled) shows the number of packets waiting
in the dejitter queue.
About the dejitter queue
All packets received from the network will go to this queue to eliminate
network jitter .
If the dejitter queue length is too short , the graph's line can touch zero during
a call and the audio can stop for a moment as the modem runs out of frames
to transmit.
If the queue's length is too long , the delay can be uncomfortably high.
You can use this graph to set a proper dejitter queue length. There should be at
least a few packets in the dejitter queue when receiving a call from the
network. You can set the dejitter queue length on the
Network page (the
setting only shows up if
Advanced mode is enabled). As a
general rule , if you
have a good network connection to the selected connector's server, set dejitter
queue length to 500ms, and if you have a 3G/4G internet connection or voice
stutters a lot, try setting the length to at least 1000ms.
