Yaesu FT-991 Operating Manual page 115

The GM (group monitor) function automatically inquires to find if there are any stations with the GM function in opera-
tion on the same frequency within communication range.
The FT-991 can then display the position and distance and other information for each group member call sign on the
screen.
Besides letting you know who is within your sphere of communications, the GM function is also a convenient method
to instantly note the relative positions of all the members in the group.
b
There are two ways to use the GM function:
(1) Display all stations operating the GM function that are within communications range (maximum of 24 stations can
be displayed)
(2) Register the ID of partners into a memory group and then display only the Group Member partners
An explanation of the two methods of starting the GM operation is given on the following pages.
Refer to the separate Operating Manual GM Edition for additional details on using the GM Functions (download the
manual from our YAESU website).
