What is Amateur (Ham) Radio?
Amateur radio, commonly known as ham radio, is a licensed radio communication service used for non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. Unlike commercial radio services, ham radio operators are permitted to build and modify their own equipment, experiment with radio technology, and communicate across town or around the world.
With over 100 years of history, amateur radio has evolved from simple spark-gap transmitters to sophisticated digital modes and satellite communications. Today, there are more than 750,000 licensed amateur radio operators in the United States alone, forming one of the largest and most technically skilled radio communities in the world.
Why People Get Into Ham Radio
- Emergency Communication: When cell towers fail during disasters, ham radio keeps working. Hurricane responders, search and rescue teams, and emergency management agencies rely on amateur operators.
- Technical Experimentation: Build antennas, design circuits, explore digital modes like FT8, and push the boundaries of radio technology.
- Community Connection: Join a worldwide network of operators. Participate in clubs, contests, and special events.
- Outdoor Activities: Parks on the Air (POTA) and Summits on the Air (SOTA) combine ham radio with hiking and outdoor adventure.
- Space Communication: Talk to astronauts on the International Space Station or bounce signals off amateur satellites.
What Can You Do With a Ham License?
A ham radio license opens up a world of possibilities that no other radio service can match:
- Talk locally via repeaters (within 50+ mile radius)
- Make worldwide contacts via HF bands
- Bounce signals off the moon (Earth-Moon-Earth communication)
- Work amateur satellites orbiting Earth
- Participate in contests and chase awards
- Provide emergency communication through ARES and RACES
- Experiment with antenna building and electronics
