Using the GM function

What is the GM function?

The GM (group monitor) function automatically listens for stations which are operating the GM function on the same frequency and
are within communication range. FTM-400DR series and FT1DR support this function.
When radio stations that you communicate with frequently are grouped and saved in the memory, the GM function is convenient
for sending and receiving messages and pictures, and for displaying a notification when group members enter into the sphere of
communication. The position information of the other stations can also be used for location and navigation purposes.
The GM function can also be used with the WIRES-X node for C4FM digital operation. When the node is a member of the group,
the node operating status can be checked from the mobile or fixed station. This allows you to know whether or not WIRES-X is
available.
When nodes operating in the GM mode are connected to each other using WIRES-X, communications with group members
becomes possible regardless of the communication range.

Before operating in the GM mode

● Using a C4FM digital transceiver as the node
To operate a node in the GM mode, a C4FM digital transceiver compatible with the HRI-200 mode is required.
As of June 2014, transceivers which can be used as a node operating in the GM mode are YAESU C4FM digital transceivers FTM-
400DR and FTM-400DE. Connect one of them to HRI-200 (See page 12).
● Using only 1 transceiver as the node
The preset search channel cannot be used during GM operation. Connect the transceiver only to the RADIO 1 jack of HRI-200.
● Opening a room for GM operation
To communicate with a wide range of group members, prepare a designated room for WIRES-X GM operation.
The room for GM operation must be opened by a node that will be a member of the room, and register the mobile, fixed and node
stations as its members.
