Badger,
we don't need TS here - if your mic is setup in windows (can record), it'll work in Aces High. There is a section in the getting started help file on the Forum on using the radio - I found it helpful to tune the V (last box on right in radio buffer) to my handle (Optiker) and pressing T to make sure my mic was working correctly. Using this method, you will hear your own voice ( short delay) and can tell if others can hear you as well. If you cannot hear yourself, go back to windows control panel and in the calibrate audio section - see if you need to enable boost - I did - . Once you have everything working properly, folks within icon range can be heard and spoken to by pressing F12. You and your squadmates can tune to channels 101-199 (all same in V box) and can talk to each other by pressing (and holding) the T key.
Hope this helps.
Regards,
Optiker
