[First message, I introduce myself in this §] I used to be a virtual ATC in the IVAO world but I had to stop because of personal reasons. Now I can do virtual ATC again but I do not want to go back into IVAO community, which I found sometimes uncompromising to beginners. Plus I am a FOSS lover and I have discovered FlightGear recently so I would like to join this community as an LFLL regular ATC. I need help to setup OpenRadar, then I'll be able to learn once more phraseology

I followed this guide: https://wiki.flightgear.org/OpenRadarGuide and now I am stuck with FGCom. The notification sounds (new planes and METAR updates) work. When I restart FGCom with the "Restart" button on the right of the COMs, the channels become red. My settings are:
FGComMode = Auto: Use the internal fgcom
FgCom Server = fgcom.flightgear.org
FgComPorts = 16661
It seems in Windows that no mic is used (the icon is not displayed) even when using the PTT button (with FGFS the mic icon is displayed). I did not manage to test OpenRadar FGCom RX because I am not sure that FGFS FGCom TX works (actually I tested and could not hear what I transmitted from FGFS to OR but not sure on which side the problem is. Both FGFS and OR were on the same frequency.
Running OpenRadar 2015-03-16 on Windows 10
Any help appreciated
