DV MODE OPERATION (Optional UT-123 is required)
■ 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 provides you with much
wider coverage range during digital voice mode operation.
•D-STAR system outline
For current repeater operation, stations that are communicat-
ing must both 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— gateway connection capability.
For example, when station B uses the gateway connection
station B can communicate with the station C!
By using the gateway connection, long distance DX commu-
nication may be possible with 144 or 440 MHz digital voice!
In the D-STAR system, an independent repeater’s operating
area is called an Area and a group that of linked repeaters via
a 10 GHz backbone is called a Zone.
