Colton Ragdale KE0CRD has successfully passed the US amateur radio exam at the age of 5
Colton got 93% of the questions in the Technician exam correct. The USA Technician exam is broadly equivalent to the UK Foundation although it doesn't have any practical assessments. A Tech licence permits the holder to run 200 watts output on four HF bands and 1,500 watts on the VHF, UHF and Microwave bands. Techs can operate Maritime Mobile, build their own equipment and run repeaters.
Colton's parents Debra K0KAI and Zeke K0XK are both radio hams and it was seeing his parents using radios and talking to one another that made him want to become involved. So he took the FCC test and passed.
