Digital Voice w/ Fwd Error Correcting – 3600 bps
Low Speed Digital Data – 1200 baud
Channel Spacing ~ 10 kHz
DD Radios (ID-1)

Germany, France, Italy, Austria & Switzerland
added this past spring
414 repeater systems internationally
2869 users registered on gateways
193 gateways on the “US Root” trust server
Over 800 users using gateways each day!
Remote Zone CQ Call
Generation 2 Gateway
Software



Gateways can now have a dynamic IP address.
The gateway synchronization process is much better.
Multicast routing enables gateway admins to pre-define a list of
up to 10 gateways that a specific "URCALL" (e.g. /COMMUTE)
will route to.




Users wishing to use the multicast group may program it into their radio. When they
transmit to "/COMMUTE" for example, their voice data is routed to all of the repeaters
configured by the gateway admin.
The ability to disable a broken/malicious gateway system.
Users register themselves now and administrators approve the
registration.
Users can specify up to 10 "terminals" or their call with singlecharacter modifiers.
Digital Voice (DV) Dongle


The DV Dongle
 Connects to your PC or Apple Mac via a USB port
 Provides encoding and decoding of compressed audio
using the DVSI AMBE2000 full duplex vocoder DSP chip.
The DVTool application available for Microsoft Windows
XP/Vista, Mac OS X Leopard, or many flavors of Linux
DV Dongle Functions
Provides AMBE 2020 interface to a computer
through USB port.

Provides a ‘RF-less’ D-Star radio




Replaces RF function with internet connection
The dongle can monitor gateway traffic
The dongle can transmit over the gateway
Many more uses

D-PRS interface






D-PRS applications allow D-STAR GPS activity to map to
standard APRS clients
D-PRS converts Icom GPS information generated by Icom DSTAR radios in GPS mode into TNC2 fomatted APRS strings.
D-PRS resides on the gateway computer
D-PRS Interface is a Windows GUI application that lets you run a
mapping program locally and watch what is happening on your
local frequency.
