Frequently Asked Questions

What is a ham radio?

Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. People use ham radio to talk across town, around the world, or even into space, all without the Internet or cell phones. It's fun, social, educational, and can be a lifeline during times of need.

Who is the Typical Ham?

Amateur Radio operators come from all walks of life -- doctors, students, kids, politicians, truck drivers, movie stars, missionaries and even your average neighbor next door. They are of all ages, sexes, income levels and nationalities. Whether through Morse Code on an old brass telegraph key, voice communication on a hand-held radio or computerized messages transmitted via satellite, all hams use radio to reach out to the world.

What does CW stand for in ham radio?

FM offers high quality audio signals, while SSB is better at long distance communication when bandwidth is restricted. Radiotelegraphy using Morse code, also known as "CW" from "continuous wave", is the wireless extension of land line (wired) telegraphy developed by Samuel Morse and dates to the earliest days of radio.

What do you mean by ham radio?

Hertz-Armstrong-Marconi. It is sometimes claimed that HAM came from the first letter from the last names of three radio pioneers: Heinrich Rudolf Hertz, Edwin Armstrong, and Guglielmo Marconi.

What's the Appeal of Ham Radio?

You can communicate from the top of a mountain, your home or behind the wheel of your car, all without relying on the Internet or a cell phone network You can take radio wherever you go! In times of disaster, when regular communications channels fail, hams can swing into action assisting emergency communications efforts and working with public service agencies. For instance, the Amateur Radio Service kept New York City agencies in touch with each other after their command center was destroyed during the 9/11 tragedy. Ham radio also came to the rescue during Hurricane Katrina, where all other communications failed, and the devastating flooding in Colorado in 2013.

You can communicate with other hams using your voice and a microphone, interface a radio with your computer or tablet to send data, text or images, or Morse code, which remains incredibly popular. You can even talk to astronauts aboard the International Space Station, talk to other hams through one of several satellites in space, or bounce signals off the moon and back to Earth!

Some hams like to build and experiment with electronics. Computer hobbyists enjoy using Amateur Radio's digital communications opportunities. Others compete in "DX contests," where the object is to see how many hams in distant locations they can contact. Mostly we use ham radio to form friendships over the air or through participation in one of more than 2000 Amateur Radio clubs throughout the country. There are over 600,000 radio amateurs in the United States and over 2,000,000 worldwide.

Why are Amateur Radio Operators also called "Hams"?

The first wireless operators were landline telegraphers who left their offices to go to sea or to man the coastal stations. They brought with them their language and much of the tradition of their older profession. In those early days, every station occupied the whole spectrum with its broad spark signal. Government stations, ships, coastal stations and the increasingly numerous amateur operators all competed for time and signal supremacy in each other's receivers. Many of the amateur stations were very powerful. Two amateurs, working each other across town, could effectively jam all the other operations in the area. Frustrated commercial operators would refer to the ham radio interference by calling them "hams." Amateurs, possibly unfamiliar with the real meaning of the term, picked it up and applied it to themselves. As the years advanced, the original meaning has completely disappeared.
