Transmitting D-PRS data

When D-PRS is selected as the GPS TX mode,
you can transmit D-PRS data.
When operating in the D-PRS mode, the
following codes are transmitted to the PC.
D-PRS code is based on APRS
(APRS ® : Automatic Packet Reporting System)

DD-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 at the same time voice is being transmitted
or received. An I-GATE is required to send
position data to the APRS server.
