![]() ![]() The DVAP has no AMBE chip like the DV Dongle. The DVAP connects to via a USB port and provides a low power two-metre simple repeater (or access point) for use with a D-STAR enabled transceiver only. Links: DVAP or DV Access Point (red bo) The DVAP is a small plastic (red) bo with a SMA stubby antenna, containing a very low power (10 mw) MHz transceiver (frequency agile) that allows a user via an Internet connected Microsoft Windows XP/Vista/Win7, Mac OS X Leopard, or many flavours of Linu based PC/Laptop/Netbooks to access the D-STAR Network. Receive only audio doesn't require any registration so non-amateurs can also take part in D-STAR as well. D-STAR Registration (see later in this article) is required if users want to 'transmit' audio. Although laptop user's can use built-in microphone/speakers, eperience has proved that a headset with a boom microphone produces the best results. Users additionally also need a good quality microphone and speakers to produce good audio. (Users need to install USB drivers prior to installing the DVTools application much like installing USB drivers for a printer for eample). ![]() The DVTool may be installed and run on Microsoft Windows XP/Vista/Win7, Mac OS X Leopard, or many flavours of Linu. (It is also used in some HF digital protocols by vendors like AOR.) Once the DV Dongle is installed and connected to a PC it requires the DVTool application to access the D-STAR repeaters and reflectors. ![]() AMBE technology is used in all D-STAR transceivers to provide efficient voice transmissions. The DV Dongle connects to via a USB port and provides encoding and decoding of compressed audio using the DVSI (Digital Voice Systems, Inc) AMBE2000 full duple vocoder DSP chip. No D-STAR transceiver is required therefore this is the lowest cost entry point to D-STAR. 1 Hardware/Software for use with D-STAR Hardware DV Dongle (blue bo) The DV Dongle is a small plastic (blue) bo containing electronic components that allow a user via an Internet connected Windows, Apple Mac or Linu based PC/Laptop/Netbooks to access the D-STAR Network (repeaters and reflectors). ![]()
