This USB-stick facillitates the use of a PC to communicate on Dstar,DMR and C4FM! Just install BlueDV (latest update supports C4FM as well now), and use the PC-microphone and PC-speakers to communicate to reflectors/talkgroups. Ideal solution to use on a laptop whilst traveling. 

Technical datasheet here

How to setup: check AMBE in BlueDV(setup screen), select comport just below that, and set the baudrate to 460800. That will make sure BlueDV will recognise the device. Check the extra image above to see the settings!
