Anthony, don't worry, you don't have or need a mode S transponder, or for
that matter a transponder of any kind. These devices are used by people who
actually fly airplanes, and are used in actual airplanes. They are not a
factor for gamers, like yourself. So, don't worry.

If you need to hear any other voices in the dark, you can always communicate
with your imaginary controllers and fellow game players via the net.

Everything will be alright, don't worry. The demons will go away soon.
