What is the GM Function?
The GM (group monitor) function automatically checks the current operating frequency
to find if other stations are operating in the DN mode with the GM function, and are
within communication range.
The GM function is a convenient method of exchanging messages, pictures and
notifications with members that are within the sphere of communications. The position
information reported from the other stations can also be used for location and navigation
purposes.
