Steve - The DVMega AMBE3000 initially came out as a 'shield' that would sit on an Arduino, with an additional audio board so you could plug in a mic / speaker and hold a QSO over a D-Star(?) network via a PC without any local RF.
The next evolution was the 'carrier board' which removed the requirement for the Arduino , and meant you could plug it directly into a PC and use the PC sound card rather than the additional audio board + Arduino.
Peter - does it look like the carrier board is doing anything other than converting USB to serial? If not, then hopefully Analog_Bridge can interface with it directly. If there is an additional microcontroller it might be best going straight into the AMBE3000
with a serial adapter
Cheers all for taking an interest in this, much appreciated.
