"Amateur Radio is a lot of fun, but the serious side can't be stressed enough," says John Bigley, President of the Nellis RAC, "We play a vital communications role during emergencies, and events such as Field Day ensure that we're ready to handle any type of disaster."
Field Day, which began in 1933, is designed to test operators' abilities to quickly set up and operate stations in the field under emergency conditions, such as a telephone or power outage. During the weekend, radio operators try to contact as many other Field Day stations as possible, simulating the fast on-air skills needed to assist local officials and served agencies during an emergency. Approximately 35,000 Amateur Radio operators across the country participated in last year's event.
Ham radio operators typically help with communication during natural emergencies such as this springs devastating tornadoes in the Midwest or the current wildfires in Arizona. However it was Amateur Radio�s impact on the events of 9-11 which has brought it to the forefront of homeland defense. It�s quite common for a community to have all of it�s communications and broadcasting equipment located at one site. When the World Trade Centers fell, so did the antennas for all of their emergency services, broadcast stations, and cell phones. Ham radio operators quickly moved in and established needed communications.
There currently are 2,755 licensed Amateur Radio operators in Clark County. Local Hams are involved with dozens of agencies such as Las Vegas and Clark County Emergency Management, the Civil Air Patrol, the Red Cross, Salvation Army, CERT, and the National Weather Service. A federal grant awarded for emergency communications training in 2002 emphasizes support for ham radio's role in homeland defense.
The Las Vegas group will set up its Field Day operations at Sunset Park and will be operating from noon Saturday June 28th until noon Sunday June 29th. "We hope that the public will come out and see firsthand what this event--and Amateur Radio--is all about," says Bigley.
Backgrounder:What is Amateur Radio?
A retired military officer in North Carolina makes friends over the radio with a ham in Lithuania. An Ohio teenager uses her computer to upload a chess move to an orbiting space satellite, where it's retrieved by a fellow chess enthusiast in Japan. An aircraft engineer in Florida participating in a "DX contest" swaps call signs with hams in 100 countries during a single weekend. In California, volunteers save lives as part of their involvement in an emergency communications net. And at the scene of a traffic accident on a Chicago freeway, a ham calls for help by using a pocket-sized hand-held radio.
This unique mix of fun, public service and convenience is the distinguishing characteristic of Amateur Radio. Although hams get involved in the hobby for many reasons, they all have in common a basic knowledge of radio technology, regulations and operating principles, demonstrated by passing an examination for a license to operate on radio frequencies known as the "Amateur Bands." These are reserved by the Federal Communications Commission (FCC) for use by hams at intervals from just above the AM broadcast band all the way up into extremely high microwave frequencies.
Who's the Typical Ham?
Amateur Radio operators come from all walks of life -- movie stars, missionaries, doctors, students, politicians, truck drivers and just plain folks. They are all ages, sexes, income levels and nationalities. But whether they prefer Morse code on an old brass telegraph key through a low-power transmitter, voice communication on a hand-held radio or computer messages transmitted through satellites, they all have an interest in what's happening in the world, and they use radio to reach out.
What's the Appeal of Ham Radio?
Some hams are attracted by the ability to communicate across the country, around the globe, even with astronauts on space missions. Others build and experiment with electronics.
Computer hobbyists find packet radio to be a low-cost way to expand their ability to communicate. Those with a competitive streak enjoy "DX contests," where the object is to see how many hams in distant locations they can contact. Some like the convenience of a technology that gives them portable communication. Others use it to open the door to new friendships over the air or through participation in one of more than 2000 Amateur Radio clubs throughout the country.
A Noble History:
Nobody knows when Amateur Radio operators were first called "Hams," but we do know that Amateur Radio is as old as the history of radio itself. Not long after Guglielmo Marconi, an Italian experimenter, transmitted the Morse code letter "s" from Poldhu, on the southwest tip of England, to St. John's, Newfoundland, in 1901, amateur experimenters throughout the world were trying out the capabilities of the first "spark gap" transmitters. In 1912, Congress passed the first laws regulating radio transmissions in the U.S. By 1914, amateur experimenters were communicating nation-wide, and setting up a system to relay messages from coast to coast (whence the name "American Radio Relay League"!). In 1927, the precursor agency to the FCC was created by Congress and specific frequencies were assigned for various uses, including ham bands.
Why a License?
Although the main purpose of Amateur Radio is fun, it is called the "Amateur Radio Service" because it also has a serious face. The FCC created this "Service" to fill the need for a pool of experts who could provide backup emergency communications. In addition, the FCC acknowledged the ability of the hobby to advance the communication and technical skills of radio, and to enhance international goodwill. This philosophy has paid off. Countless lives have been saved where skilled hobbyists act as emergency communicators to render aid, whether it's during an earthquake in Italy or a hurricane in the U.S.
Why Do They Call Themselves "Hams?"
"Ham: a poor operator. A 'plug.'"
That's the definition of the word given in G. M. Dodge's "The Telegraph Instructor" even before radio. The definition has never changed in wire telegraphy. 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 same wavelength-or, more accurately perhaps, 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 in true "Yankee Doodle" fashion and wore it with pride. As the years advanced, the original meaning has completely disappeared.
What Are the Amateur Radio Bands?
Look at the dial on an old AM radio and you'll see frequencies marked from 535 to 1605 kilohertz. Imagine that band extended out many thousands of kilohertz, and you'll have some idea of how much additional radio spectrum is available for amateur, government and commercial radio bands. It is here you'll find aircraft, ship, fire and police communication, as well as the so-called "shortwave" stations, which are worldwide commercial and government broadcast stations from the U.S. and overseas. Amateurs are allocated nine basic "bands" (i.e. groups of frequencies) in the High Frequency (HF) range between 1800 and 29,700 kilohertz, and another seven bands in the Very High Frequency (VHF) bands and Ultra High Frequency (UHF) ranges, as well as Super High Frequency (SHF) bands. Even though many Amateur Radio conversations may be heard around the world, given the right frequency and propagation conditions, Amateur Radio is basically two-way communication.
Where Do I Get More Information?
The three best ways to learn about Amateur Radio are to listen to hams on the "Amateur Bands," read about Amateur Radio in the numerous books and magazines devoted to the subject and, best of all, talk to hams face-to-face. Hams take pride in their ability to "Elmer" (teach) newcomers the ropes to get them started in the hobby. There is probably an Amateur Radio club near you that will welcome your interest.
