Since I have not had that much luck with Viacomm, I set out to make a profile that would allow me to perform most of the radio functions in DCS. This is my first attempt at a profile for the radio dialogues for the Flaming Cliffs modules. I've tested it with the F15 and A10A. It seems to work okay.
Minor notes: You'll have to set a PTT switch in the profile and the same switch in DCS for the activations to work properly. I have not yet managed to JTAC working correctly for the A10A, so those commands have been left out for now.
