How open radio?

[Vespa]

Sorry for the silly question...but I cannot find the Keys to open the radio chat to request ground power. Usually (A-10C) I use LAlt & Tn+

These have no effects in F-86 Cold start scenario (this is what I'm trying to play)

Thanks for help

You can find this out in game. Look at the Communications list in the controls.

 

It's / for the menu on the ground.

ralt+/ for the menu when off the ground.
