I do hope you won't object to much but I take exception to your title and hope you will change it.
Tesla didn't ever use Radio he used Wireless , In 1890 without amplifying valves,transistors,diodes or chips in fact all he had was wood and Brass he built a four channel proportionally controlled Boat .
