It is not really designed to ID a particular make and model of a radio, although it could if enough data were available for comparison. It is more similiar to ballistics matching than fingerprinting, in that there are a lot of variables that can change slightly. As to the question, this almost seems like there is something "different" between a part 90 radio and a part 95 radio. Since the certification specs are the same, there is really nothing that a person can look at (over the air) to say whether a radio is a part 90 or a part 95 designated radio. A part 90 radio will meet all part 95 specs, assuming power is kept below 50 watts. The only difference is that "95" is entered on the application for certification.
