About the DR function

You can easily use D-STAR repeaters with
the D-STAR Repeater (DR) function. With this
function, you can select the preset repeater or
frequency in "FROM" (access repeater), and a
target call sign in "TO" (destination) on the DR
screen, as shown right.
NOTE: If the repeater set in "FROM" (Access
Repeater) has no Gateway, you cannot make a
Gateway call.

Ways to Communicate with the DR function

With the DR function, the transceiver has 3 ways
to communicate.
Local Area call: To call through your local area
(access) repeater.
LYou can use an FM repeater.
Gateway call: To call through your local area
(access) repeater, repeater
gateway, and the Internet to your
destination repeater or individual
station's last used repeater,
using Call Sign Routing.
Simplex call: To call another station not using
a repeater.
NOTE:
• Using the repeater list is required to use the DR
function. (p. 13-15)
• 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 the Time-Out Timer function
for the DV Repeater operation. The timer limits
a continuous transmission. Warning beeps will
sound approximately 30 seconds before time-out
and then again immediately before the time-out.
To begin Digital mode communication using other than the DR function
To begin Digital mode communication using other
than the DR function, you can use the VFO mode,
Memory mode, or Call Channel mode. This manual
description focuses on the DR function operation,
which can be easily set up. If you want to use
other than the DR function, see the procedures
as described to the right, or select a repeater in a
Memory channel.
To display the DR screen, hold down
1 second.
