DV Dongle

The DV Dongle connects to your PC or Apple Mac via a USB port and provides encoding and decoding of compressed audio using the DVSI AMBE2000 full duplex vocoder DSP chip. AMBE technology is used in all D-Star radios to provide efficient voice transmissions. It is also used in some HF digital protocols by vendors like AOR. The DVTool application used with the DV Dongle may be installed and run on Microsoft Windows XP/Vista, Mac OS X Leopard, or many flavors of Linux.

What is it?
When a DV Dongle is connected to a PC or Mac and used with DVTool software, an amateur radio operator can connect to the international D-Star gateway network and receive/transmit just like a D-Star radio user.

How does it work?
Each D-Star radio includes an AMBE2020 voice compression chip provided by Digital Voice Systems, Inc (DVSI).  The DV Dongle includes an AMBE chip and logic to connect it to a USB port on a PC or Mac.  This allows the computer to ďspeakĒ the same voice protocol as D-Star.  The DVTool software connects to participating gateways and encodes/decodes the voice using the DV Dongle.

What kind of computer is needed (what ports)?
A minimum suggested configuration includes a PC or Mac with 2.0GHz processor with 512MB of RAM and a USB 2.0 full speed port.
