Just to add a little realism I want to change ATC frequencies and Transponder myself rather than have FS do it for me automatically. How can I disable the automatic setting of frequencies?Chris

this question doesn't belong in this forum,but I'll give you a suggestion though: you can always manually tune in a frequency or a sqauwk code:don't push "1" in the ATC menu to autotune,but just dial in the frequency into COM1 and then you can select the options
