Input the IP address of the multicast group. Radios will only communicate to
radios within the same group. There are three different modes to select which dictate how a
radio behaves within a group:
•
Active:
Radio may send and receive PTT audio on this group.
•
Inactive:
Group is disabled, no PTT audio will be sent or received.
•
Monitor:
Radio may listen to PTT audio from other users on this group, but may
not talk.

Beep PTT Override
–
When the PTT button is pressed while another user is speaking,
a warning beep will be played. This setting controls the volume of the Beep as a percent (%) of
the speaker volume above. Pressing the PTT button three times (and holding on the third) within
1s will allow a user to override the channel and speak.
PTT HQ Link Notifications
–
When the PTT button is pressed twice within 1s, an audio notification
will read out the SNR level to the user-specified HQ node. If the level transitions option is enabled,
the notification will be played automatically when the SNR crosses the specified thresholds. The
SNR thresholds can be set by first choosing the number of levels desired, and then moving the
sliders accordingly.
