D-STAR INTRODUCTION
7-3
With the DR function, the transceiver has three ways to
communicate, as shown below.
• Local area call : To call through your local area (ac-
cess) repeater.
• Gateway call : To call through your local area (ac-
cess) repeater, repeater gateway and
the internet to your destination re-
peater or individual station’s last used
repeater, using call sign routing.
• Simplex call : To call another station not using a re-
peater.
NOTE:
• Using the Repeater List is required to use the DR function. (pp. 9-24 to 9-34)
• Before operating in the duplex mode, be sure to check whether the repeater is busy, or not. If the repeater is busy,
wait until it is clear, or ask for a “break” using a method acceptable to your local procedures.
• The transceiver has a Time-Out Timer function for DV operation. The timer limits a continuous transmission. Warn-
ing beeps will sound approximately 30 seconds before time-out and then again immediately before time-out.
