What didn't work specifically? Thats good. that means the MIc works, XSB is setup correctly for push-to-talk, and that it will transmit actual voice (rather than static). This is the crux of the problem. What do you *think* you need to do? What are you expecting to happen? How do you think it should all work? (Im interested in your response, because I think that everything is actually working, it's just that your expectation as to what should happen may need some education here). - CK. Hints: Did you tune your COM1 radio? Do you see a list of Active Controllers on your Screen/Who's Online Window? Can you voice-hear other air traffic in the area where there is an active controller? Have you EVER gotten voice to work in VATSIM, or is this your very first attempt to use Voice?
