|Ham Radio, more technically known as Amateur Radio, is an FCC licenced
radio service available to the citizens of the United States and its possessions.
Although Amateur Radio seems to be a small part of radio
as we know it today, it was very
instrumental in the development of early radio.
Amateur Radio operators all over the world, licensed by their home country, enjoy the very same hobby. Even the late Senator Berry Goldwater and the late Jimmie Stewart held Amateur Radio licenses. Well knowns Patty Loveless, Ronnie Milsap and Walter Cronkite also hold Amateur Radio licenses.
Amateur Radio is a popular hobby in which an individual operates his or her own radio station. Amateur radio is often called ham radio, and the operators are frequently referred to as hams. Hams can send radio messages by voice or by International Morse Code to other radio amateurs throughout the world. About a million people participate in amateur radio. Boys and girls younger than 7 years old have operated their own amateur radio stations.
Amateur radio differs from a type of radio operation called citizens band, or CB, radio. Citizens band carries fewer channels than amateur radio and is more limited in the power and range of its signal.
Many hams enjoy talking with other radio amateurs in faraway places. When contacting hams in other countries, they have little difficulty with language barriers. Many hams around the world speak English. When communicating by means of International Morse Code, amateurs may use an internationally accepted set of three-letter signals. These signals are called Q signals because they all begin with the letter Q. For example, the signal QTH? means "What is your location?" Q signals enable amateur-radio operators without a common language to understand each other.
Some radio amateurs have developed special equipment for sending television pictures over radio waves. Other radio amateurs send messages all over the world by bouncing their signals off the moon. Hams even use their sets to transmit information from one computer to another.
One technically challenging activity involves building and using an amateur radio communications satellite. Many nations have allowed amateur radio communications satellites to "hitchhike" into orbit as part of the launch of other satellites. Most of these communications satellites have been called Oscars. The word Oscar comes from Orbiting Satellite Carrying Amateur Radio. Many schools tune in Oscars to provide students with firsthand experience in space science.
In the United States, the Federal Communications Commission (FCC) issues amateur radio licenses. As of April 15, 2000 there are three classes of licenses: (1) technician, (2) general, and (3) extra class. Starting with the technician level, each license gives greater privileges and requires greater knowledge and abilities.
Many local ham radio clubs offer courses that prepare amateurs to take the technician license test. One of Colorado Springs' oldest and largest clubs is the Pikes Peak Radio Amateur Radio Association (PPRAA).
The technician license requires only a written examination, but restricts the frequencies available to the technician. All amateur licenses, are good for 10 years and may be renewed.
The general license requires greater technical knowledge and familiarity with FCC rules. The general license requires the ability to copy code at a rate of five words a minute. It provides the amateur with a wide variety of privileges, including the increased use of voice and code transmission.
The extra class licenses provides the entire range of frequency privileges and requires the highest level of detailed knowledge. The code speed requirement is 5 words a minute for the extra class license.
Amateurs pioneered the development of radio in many other important ways. In 1919, a ham named Frank Conrad used his station in Wilkinsburg, Pennsylvania, to transmit recorded music for the entertainment of people in the area, who listened on small crystal sets. This use of an amateur station helped lead to commercial radio broadcasting. In the late 1930's, a United States radio amateur named Grote Reber built the first radio telescope with a dish antenna and received radio noise from outer space. In 1961, the first amateur radio satellite, Oscar 1, was launched. This was also the first nongovernmental, noncommercial satellite. The first direct satellite communication between the Soviet Union and the United States took place via the Oscar 4 amateur radio satellite in 1965.
