About the Digital Group ID (DG-ID) feature
Digital Group ID (DG-ID) function allows using the two-digit ID numbers to communicate
only with specific group members. The desired DG-ID number from 00 to 99 is set in
advance by all the group members. This ID number may be set separately for transmit
and receive, when the same ID number is set for both transmit and receive, only group
members with the same ID number will be heard. This feature may be used to limit com-
munication only to group members that have the same DG-ID number. The GM function
may also be utilized to automatically monitor whether or not group member stations with
the same DG-ID number are operating within communication range.
The DG-ID number 00 detects signals with all ID numbers. Normally setting the ID
number to “00” for both transmit and receive will permit reception of the signals from all
other stations using the digital C4FM mode, regardless of the transmit DG-ID number
settings of the other stations.
Also note that when the receive DG-ID number of the transceiver is set to a DG-ID
number other than “00”, received signals that do not have the same DG-ID number may
not be heard.
2. When accessing a C4FM digital repeater controlled by a DG-ID number, set the
transmit DG-ID number of the FTM-300DR/DE to that of the repeater input. Even in that
case, if the receive DG-ID number of the FTM-300DR/DE is set to “00”, all the downlink
signals from the repeater may be received.
Communicating with the DG-ID feature
•
Digital C4FM mode transceivers compatible with the DG-ID function are required in order to
utilize this function.
•
If the firmware is not compatible with the DG-ID function, update to the latest firmware to use
the DG-ID function. The latest firmware is available on the YAESU website.
