Using the GM Function
What is the GM Function?
The GM (group monitor) function monitors the set frequency to find if there are any stations operating with the GM function within communication range.
The FT-991 can then display the position, distance and other information for each group member call sign on the screen.
Besides identifying GM stations that are within the sphere of communications, the GM function is also a convenient method to instantly note the relative positions of all the members in the group.
A maximum of 5 groups can be created in the GM function of the transceiver.
A maximum of 24 stations (excluding this station) can be registered as Members in each group.
Note:
To utilize the GM function, all group members must operate on the same frequency.
