■ About D-STAR system
In the D-STAR system, repeater linking via a 10 GHz band
backbone and internet network (gateway connection) capa-
bilities are available. This system allows you to much wider
coverage range during Digital voice mode operation.

Station C
For current existing repeater operation, stations that are com-
municating must be in the same repeater's operating area.
However, in the D-STAR system as in the illustration at left,
the repeaters can be linked via the system repeaters (with a
10 GHz signal). Thus stations A and B can communicate even
though they are in different repeater operating areas.
Also, the D-STAR system repeaters are connectable through
the internet network— gateway connection capability.
Repeater B
For example, when station B uses the gateway connection
440 MHz signal
station B can communicate with the station C!
By using the gateway connection, long distance communica-
tion like DX operation may be possible with 144 MHz/440MHz
digital voice!
Station B
In the D-STAR system, independent repeater's operating
area is called as Area and a group that linking repeaters via a
10 GHz backbone is called as Zone.

DIGITAL MODE OPERATION
NOTE: The digital repeater for IC-V82/U82 (144 MHz/440
MHz of amateur radio bands operation) is not available at
present of October 2004. It will be designed in the future.
