Why don't you just set your radio 5 to yourself?
I check my mic for game use by typing ".radio 5 kermit". I press the T key and I can talk to myself.

I will hear exactly what others hear.
Please don't type exactly what I wrote in the quotes. I don't want to hear you noobs squeaken in my ears.
Type dot, then radio, then the radio number, then your game name
example: .radio 5 Kev367th
