REPEATER OPERATION— VOICE

I 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 D
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.
For example, when station B uses the gateway connection
station B can communicate with the station C!
By using the gateway connection, long distance communica-
tion like DX operation may be possible with 1.2 GHz digital
voice!
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.
About time-out timer function
The ID-1 has a time-out timer function for digital repeater
operation. The timer limits a continuous transmission for ap-
prox. 10 min. Warning beeps will sound before 30 sec. (ap-
prox.) and just before the timer functioning.
