      Getting Acquainted with Ham Radio

      IN THIS CHAPTER

      Ham radio invokes a wide range of visions. Ham radio operators (or hams) are a varied lot — from go-getter emergency communicators and radiosport competitors to casual chatters to workshop tinkerers. Everyone has a place, and you do too.

      Hams employ all sorts of radios and antennas using a wide variety of signals to communicate with other hams across town and around the world. They use ham radio for personal enjoyment, for keeping in touch with friends and family, for public service, and for experimenting with radios and radio equipment. They communicate by using microphones, computers, cameras, lasers, Morse keys, and even their own satellites.

      Hams meet on the air, online, and in person, in groups devoted to every conceivable purpose. Hams run special flea markets and host conventions large and small. Some hams are as young as 6 years old; others are centenarians. Some have a technical background, but most do not; it’s not necessary to enjoy ham radio. One thing that all these diverse people share, however, is an interest in radio that can express itself in many ways.

      This chapter gives you an overview of the world of ham radio and shows you how to become part of it.

      HAM: NOT JUST FOR SANDWICHES ANYMORE

      Everyone wants to know the meaning of the word ham, but as with many slang words, the origin is murky. Theories abound, ranging from the initials of an early radio club’s operators to the use of a meat tin as a natural sound amplifier. Of the many possibilities, the following theory seems to be the most believable.

“Ham: a poor operator” was used in telegraphy even before radio. The first wireless operators were landline telegraphers who brought with them their language and the traditions of their much older profession. Government stations, ships, coastal stations, and the increasingly numerous amateur operators all competed for signal supremacy in one another’s receivers. Many of the amateur stations were very powerful and could effectively jam all the other operators in the area. When this logjam happened, frustrated commercial operators would send the message “THOSE HAMS ARE JAMMING YOU.” Amateurs, possibly unfamiliar with the real meaning of the term, picked it up and wore it with pride. As the years advanced, the original meaning completely disappeared.

Exploring Ham Radio around the World

      Although the United States has a large population of hams, the amateur population in Europe is growing by leaps and bounds, and Japan has an even larger amateur population. With more than 3 million hams worldwide, very few countries are without an amateur (see the nearby sidebar “Where the hams are”). Ham radio is alive and well around the world. Listen to the ham radio frequency bands on a busy weekend and you’ll see what I mean!

      Hams are required to have licenses, no matter where they operate. (I cover all things licensing in Part 2 of this book.) The international agency that manages radio activity is the International Telecommunication Union (ITU; www.itu.int/en). Each member country is required to have its own government agency in charge of licensing inside its borders. In the United States, hams are part of the Amateur Radio Service (www.fcc.gov/wireless/bureau-divisions/mobility-division/amateur-radio-service), which is regulated and licensed by the Federal Communications Commission (FCC). Outside the United States, amateur radio is governed by similar rules and regulations.

      WHERE THE HAMS ARE

      The International Amateur Radio Union (IARU; www.iaru.org) counts about 160 countries with a national radio society. Counting all the hams in all those countries is difficult, because in some countries, amateur stations and operators have separate licenses. The United States alone had more than 760,000 hams as of 2020 — the most ever. You may not be surprised to hear that China has the fastest-growing amateur population; Thailand and India aren’t far behind.

Because radio signals know no boundaries, hams have always been in touch across political borders. Even during the Cold War, U.S. and Soviet hams made regular contact, fostering long personal friendships and international goodwill. Although the Internet makes global communications easy, chatting over the airwaves with someone in another country or participating in a planet-wide competition is exciting and creates a unique personal connection.

Tuning into Ham Radio

      Your interest in ham radio may be technical, you may want to use ham radio for public service or personal communications, or you may just want to join the fun. These are all perfectly valid reasons for getting a ham radio license.
