Well I can't answer that question with 100% certainty but I do know the
Fullerton Airport was founded in the late 20's, and an educated guess
would be that KFI wasn't around at that time.


I think it's just the opposite. Commercial radio broadcasting began in the
early '20s and many of the oldest stations were assigned three-letter
identifiers and still use them. If Fullerton goes back to just the late
twenties it's entirely possible that the radio station was there first.
