I have been looking into buying Radar Contact for FS9. It looks like a fantastic program however I have put a lot of time and effort into my current ATC package as far as using editvoicepack. I have created hundreds of callsigns and airport names and "tweaked" it just how i like. But Radar Contact obviously is a more realistic ATC program. So my questions for you is if I go with RC will all my editvoicepack work be flushed? My main concern is the callsigns, is there an entirely new voice program that would require me to remake all of these callsigns?
