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 HAM sta-
tion on another repeater through the internet.
• The transceiver can be operated in the digital voice
mode, including low-speed data operation, for both
transmit and receive.
About the DR (D-STAR Repeater) mode
The DR (D-STAR Repeater) mode is one mode you can
use for D-STAR repeater operation. In this mode, you
can select a preprogrammed repeater or frequency in
"FROM" (the access repeater or simplex), and UR call
sign in "TO" (destination), as shown to the right.
NOTE: If the repeater, set to "FROM" (Access Re-
peater) has no Gateway call sign, you cannot make
a gateway call.
