What can you do with a licence?
Far more than "talk on a radio". Here is what people actually spend their time on.
Talk locally, every day
Handheld radios plus "repeaters" - shared receivers and transmitters on hilltops and towers - give you reliable coverage across a city or a county. Most clubs run a scheduled on-air get-together each week that anyone can join.
Reach the other side of the world
On the shortwave bands your signal bounces off the ionosphere and comes back down hundreds or thousands of miles away. Working a station in New Zealand from your garden, on a hundred watts and a wire, never stops being satisfying.
Work satellites - and sometimes the Space Station
There are amateur radio satellites in orbit right now that you can use with a handheld radio and a small antenna. Astronauts on the International Space Station also carry amateur gear and make contacts, including scheduled calls with schools.
Send data, not just voice
Digital modes turn your radio into a data link. Some, like FT8, decode signals far too weak to hear. Others send text, files, email, or slow-scan television pictures. All of it over the air, with no infrastructure in between.
Help when it counts
Trained amateur operators support emergency management, hospitals, shelters and search-and-rescue teams when normal communications are overwhelmed or destroyed. Volunteers also handle communications for marathons, parades and bike races - good practice and genuinely useful.
Build things
You may design, build and operate your own transmitters, receivers and antennas. People build radios from kits, put stations on solar power, launch high-altitude balloons, and bounce signals off the moon.
Compete and collect
Contests, awards for contacting all 50 states or 100 countries, activating parks and summits with a portable station, foxhunting for hidden transmitters - if you like a target to chase, there are plenty.
Where to go deeper
Our wiki covers each of these in detail - bands and privileges, equipment, antennas, propagation, digital modes, satellites and emergency communications. It is community-edited, so licensed operators can add what they know.
