D-PRS
D-STAR Packet Reporting System (D-PRS) is a mode
that simultaneously sends position data received from
the internal GPS receiver, using the slow speed data
packet space, along with voice audio in the DV mode�
In the Analog mode, you can transmit or receive only
voice audio or data at one time� However, a D-PRS
capable radio can transmit or receive message data
or GPS position data simultaneously when voice is
being transmitted or received� An I-GATE is required
to send position data to the APRS server�
