Extended Learning
Congratulations!
You’ve earned the Radio merit badge — one of the oldest badges in Scouting, and one that connects you to a tradition stretching back to Marconi’s first spark. You now understand more about the invisible world of radio waves than most adults ever will. You can read a spectrum chart, explain how your phone finds your location, identify propagation modes, and discuss the difference between AM and FM with real understanding.
But here’s the thing about radio: the badge is just the beginning. The spectrum is vast, the technology is constantly evolving, and the community of radio enthusiasts is one of the most welcoming in any hobby.

Get Your Ham License
If you haven’t already, earning your Technician amateur radio license is the most impactful next step. The exam is 35 multiple-choice questions, study materials are free online (hamstudy.org, arrl.org), and many clubs offer free testing through the Laurel VEC. With a license, you can get on the air and start making real contacts.
Explore Software-Defined Radio
For about $25, an RTL-SDR USB dongle and free software (SDR#, CubicSDR, or GQRX) turn your laptop into a radio receiver covering 24 MHz to 1.7 GHz. You can listen to aircraft communications, weather satellites, amateur radio, and more — all from your desk.
Build Something
Radio is a builder’s hobby. Start with simple projects:
- A tape-measure Yagi antenna (covered in Req 8d3)
- A crystal radio — a receiver that requires no batteries, powered entirely by the incoming radio wave
- A QRP (low-power) transmitter kit — transmit with 5 watts or less and see how far your signal reaches
Attend Field Day
ARRL Field Day (held the fourth weekend of June every year) is the largest amateur radio event in the country. Clubs set up temporary stations in parks and fields, operate for 24 hours, and welcome visitors. It’s the perfect way to experience ham radio firsthand with no commitment.
Try This Next
- Join your local amateur radio club. Find one at arrl.org/find-a-club.
- Activate a park for POTA. Parks on the Air (parksontheair.com) lets you operate a portable station from any national or state park.
- Listen to the International Space Station. The ISS has an amateur radio station (call sign NA1SS) and sometimes makes scheduled contacts with schools and Scout groups.
- Try a contest. The ARRL Rookie Roundup is designed specifically for new operators — low pressure, lots of friendly contacts.
- Volunteer with ARES. Your local Amateur Radio Emergency Service team provides backup communications for disasters and public events. Training is free and the experience is invaluable.
