While in game go to preferences from the clipboard then "voice". Make sure wave-in is not enabled. Enable the beeps for range and channel. Then while in game tune the radio voice channel to your own game id to test it. If it were me I'd tune to "Irwink". Then hit the "T" key to transmit on channel and you should hear a beep and then talk. You should hear yourself. To find out if you're transmitting on range channel hit F12 when others are nearby and ask for a radio check. I'm no expert but hope it helps.
