You might have to sign on the site to see this but they won't bother you there(emails and such), so it's worth it. Great site if you like missions. Instructions on how to make very realistic sounding radio call's. http://www.flightsimulatorxmissions.com/modules.php?name=Forums&file=viewtopic&t...
Sounds confusing at first especially is your not familiar with messing around with audio but it really is pretty easy.

I'll be looking for your mission.
