I have a new radar box. I assumed that, when receiving a message, the software first checks your database and then, if it doesn't find the aircraft, it goes online and finds the info. If I receive a Hex code and aircraft but part of the information for that aircraft is incomplete ( eg. operator or aircraft type), and I fill in the missing info using database explorer, I had assumed that, now my database is correct, the next time the aircraft appears I will get the whole information displayed. However, I find that the next day frequently the data for that aircraft still shows incomplete and my data base (in data base explorer) has reverted to iits incomplete form. Am I doing anything wrong?
