Getting Started
Welcome to the world of amateur radio! This chapter will take you from zero to your first contact on the air, covering everything you need to know to begin your journey as a HAM.
What is Amateur Radio?
Amateur radio (also known as HAM radio) is a long-established radio communication hobby and service. Millions of licensed operators around the world -- commonly calling themselves HAMs -- use radio waves for communication, experimentation, and technical exploration. Unlike commercial broadcasting or professional communications, amateur radio is a non-profit activity pursued for personal interest, technical research, and public service.
The Origin of "HAM"
There are several stories about where the name "HAM" comes from:
- Early callsign theory: In the early 1900s, Albert Hyman, Bob Almy, and Poogie Murray at Harvard University set up an amateur station using the callsign H-A-M (from their last names). Their station became well-known during a congressional hearing about frequency interference with a commercial station.
- Informal nickname: Professional telegraph operators used to call clumsy amateurs "ham-fisted." Over time, the term shifted from an insult to a badge of pride among amateur radio enthusiasts.
Regardless of its origins, HAM is now the universally recognized identity for amateur radio operators worldwide.
Why Get Into Amateur Radio?
Amateur radio offers a remarkably diverse range of attractions:
Technical Exploration
Amateur radio spans electronics, electromagnetic wave propagation, antenna design, digital signal processing, and more. You can build your own transceivers, design and erect antennas, and explore how radio waves travel across different frequency bands. It is an outstanding platform for turning theoretical knowledge into hands-on practice.
Global Communication
Using high-frequency (HF) radio, you can talk directly with HAMs around the world -- no internet or satellite relay needed. When propagation conditions are favorable, just a few watts of power can bridge an ocean and connect you with a station on another continent. This experience is unlike anything other communication technologies can offer.
Emergency Communications
During earthquakes, hurricanes, floods, and other natural disasters, when telephone networks and the internet go down, amateur radio is often the last line of communication still standing. Emergency management agencies in many countries incorporate amateur radio into their disaster response plans.
Community and Social Life
Amateur radio has a vibrant global community. You can chat with local HAMs through repeaters, participate in contests and on-air events, and meet like-minded friends at hamfests and club meetings.
Satellite and Space Communication
Amateur radio has its own satellites (OSCAR series), and you can even make contact with astronauts aboard the International Space Station (ISS) through its onboard amateur radio equipment.
What Can You Do With Amateur Radio?
Here are some of the most common activities and applications:
| Activity | Description |
|---|---|
| Voice contacts | Communicate using FM, SSB, and other voice modes |
| Morse code (CW) | The oldest mode of radio communication, still popular today |
| Digital modes | FT8, RTTY, PSK31, and other computer-assisted communication |
| Satellite communication | Use amateur satellites for long-distance contacts |
| Moonbounce (EME) | Bounce signals off the Moon's surface to make contacts |
| APRS | Automatic Packet Reporting System for position tracking and messaging |
| Emergency communication | Provide critical comms support during disasters |
| Contests | Compete to make as many contacts as possible in a set time |
| SOTA / POTA | Summits on the Air / Parks on the Air -- portable operating from peaks and parks |
| Homebrew equipment | Build your own transceivers, antennas, and accessories |
| Fox hunting | Use directional antennas to locate hidden transmitters |
