I heard FS2002 has the autotune feature as standard so you can concentrate on your flying without having to tune your radio frequencies for contacting ATC towers, but how do you switch it to manual settings? I know it's more difficult, but more realism if you can perform it properly! I want to learn how to tune com radio frequencies whenever I need to contact ATC. I'm not sure how good I can fly during tuning radios & hope I won't struggle, but I'll give it a try anyway. I would also want the same for FS2004. Wink
