I've just come to notice that I'm using my text channels less and less lately because vox is simply so much better. I don't think I've EVER used all four text channels, but it would be nice to have another tunable vox channel. Can I trade a text channel for a vox channel? This is how I'd use an extra vox channel:
F12 - Area channel
T - Squadron level/command channel
Y - Flight level/wingman/gunner channel
Thanks
