My CFI, bless his heart, taught me to set the first digit LAST when changing the transponder, precisely for this reason.redbeardmark said:1200, 7500, 7600, 7700. It is simply outrageous that the FAA would expect us to remember ALL FOUR squawk codes.Since I can't remember them, they are on the home-made checklist in the airplane(along with tower lights... red light, green light... oh, it's so confusing).
