16 D-STAR

D-STAR INTRODUCTION
• In the original D-STAR (Digital Smart Technologies for
Amateur Radio) plan, JARL envisioned a system of
repeaters grouped together into Zones.
• The D-STAR repeater enables you to call a D-STAR
station in another area through the internet.
• The transceiver can be operated in the digital voice mode,
including low-speed data operation, for both transmit and
receive.
Note:
◆ Before starting D-STAR, the following steps are needed.
STEP 1: Enter your Callsign in the transceiver.
STEP 2: Register your Callsign to a gateway repeater. Refer to
the User Guide in detail.
