DVMEGA DVSTICK-30

Take part in the D-Star or DMR network with a radio, only with a USB vocoder! {

All digital modalities on Radio Ham require a vocal codec (coding / decoder, or Vocoder (vocal codec)). The purpose of a codec is the transformation of the voice into a flow of digital data and vice versa, from digital information to analogous item. During this transformation a lot happens within the codec of a simple analog / digital conversion. The goal is to reduce the speed of data as much as possible, since this will require a lower bandwidth in the limited radio spectrum. This is achieved by reducing and compressing the voice in various ways, on the analog and digital side. These procedures are quite elaborate and difficult to develop and therefore protected by patents. The developer then pours his ideas into the hardware chip and sells it to radio producers and other devices. {

Since the digital radioamatory systems borrow the technology from the commercial systems, the definitions of the codecs have also been adopted. Although free source codecs are available (free as in the free speech), these free codecs are not compatible with commercial systems because they use other procedures. So we have to live on the radio with these existing commercial codecs. Each digital radio for D-Star, DMR, P25, C4FM, NXDN, etc. Contains a codec chip of this type, you buy it with the radio. Now, if you want to participate with a current radio, you still need a codec chip to transform digital data. This is exactly what DVmega DV-30 does. {

dvmega dvstick-30 contains a codec produced by the DVSI manufacturer, the AMBE-3000 ©. This is a codec chip to the state of the art, which supports various coding systems. The result is that you can use the DVSTICK-30 with suitable software with different systems such as DMR or D-Star, in the furious perhaps with other systems such as software developments. 
A software suitable for use with dvstick-30 is blue dv of pa7lim. This software is available for many platforms such as Windows, MacOS and Linux and with suitable hardware (OTG compatible) also on Android and iOS. You need a cap or microphones and speakers for your computer,Or use the integrated microphone / speaker of your notebook. The PTT coding is performed via a software button. Another software is Openv from DL5Di, but this requires more work how to fill in the software alone.

The advantage of such a "less radio" application on Stereo radio is the possibility of staying in contact with friends at home when traveling without a radio, or there are no suitable digital repeaters nearby. The requirements for internal data speed are - thanks to the capable chip codec - remove low, usually an ISDN line with 64 Kbps is absolutely enough.
