Abstract : An experimental evaluation has been made of an RCA AVQ-65 airtraffic control transponder modified, in Mode D, so as to reply if and only if interrogated with its own preset reply code. Successful operation of the modified transponder was verified, and some key circuit limitations were explored and improved upon. (Author)
