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
