DVMEGA GMSK modem for Arduino
The card DVMEGA-GMSK is a modem for GMSK modulation, which is used as a screen to select Arduino hardware. To build a complete Node adapter requires a different computer (a Raspberry Pi will do) and radio (9k6).

DVMEGA-GMSK Modem Principioingrandimento DVMEGA GMSK Modem working principle
CMX589 DVMEGA card modem chip GMSK uses and is used as a shield for Arduino Mega 2560, Arduino Arduino Mega 128 or ONE. The Arduino controls the modem with the help of software freely available. GMSK signals received are decoded from the modem and is then transferred via USB to a computer. Transmit-wise the digital data are sent from the computer to the Arduino and the modem, which then produces a signal GMSK used to modulate the radio connected. The radio link is via a standard data connector 6pin MiniDIN.

A computer program is available for Windows PC and Pi raspberyr. Using Yahoo groups, the author offers various programs like ircDDBGateway and G4KLX PCrepeaterController. With these programs and above the hardware mentioned a local hotspot for digital modulation can be built. The advantage is that, due to the use of a programmable software modem on the Arduino, the function can be adopted for future developments. For example, it would be possible to extend the modem function not only for D-Star Icoms mode, but also for Yaesus ' Fusion System ' C4FM modulation or other digital systems (es DMR).

Please take into consideration local regulations relating to the construction and use of such radio systems. The combined products do not have the CE mark and should only be used by licensed radio amateurs.
