There is the option of setting the VOX volume to 0, so you can not hear it
Ok, you loose squad VOX also, but then again squad can use text buffer.
As people get mad getting check6 calls, I have stoped to give em. That frees a button on the stick also
You can record your own check6 sound. That way you could record silence or eg. your kid saying "look out" or sumting sweet

I agree that its your own responsibility to check your 6.
Some times I do wonder not getting one, when I see a red plane chased by 15 green planes, sneaking on my 6.
Meny times people dont even want to give the check6 call, as you are lineing up their kill.
I have also seen when high ranked players "drag" a con from their 6 close to me, hoping that the con leaves them alone and jump me. A dirty trick, but just goes to show, that you really have to check your 6.
So check your own 6, that gives you a better SA and makes you a better player
