Being old, lazy and a creature of habit, I find it convenient to have the same channel freqs assigned to the same entities in every mission, i.e. AWACS is always Com2 Ch 2 125 Mhz, flight is always Com1 CH 1 230 mhz, Departure tower is Com 2 CH 1 freq varies, etc. To facilitate this I have a standard .lua doc of channel listings for each map that I paste into my missions files using WinRAR. Pretty easy and saves time. Example attached.
