Testing voice channel

[Leisure]

I tried voice channel a bunch of times with someone on the purple channel but I think they were busy in a battle. I was wondering how to hear myself in order to tell if I can be heard by others. Just want to be sure my mic is working in game, thanks.
I can hear others playing in game.

Go online, tune the radio to yourself by entering your name in the last channel box. The use 't' to transmit and speak.

I will try that.

Thanks
