What is HAM Radio
Have you ever wondered why we radio amateurs are
called Hams? Well it goes something like this--the word ham was applied in 1908
and was the call letters of one of the first amateur wireless stations operated
by some members of the Harvard Radio Club (sic). They were Albert Hyman, Bob
Almy and Peggie Murray. At first they called their station Hyman-Almy-Murray.
Tapping out such a long name in code soon called for a revision, and they
changed it to Hy-A1-Mu, using the first two letters of each name. Early in 1909
some confusion resulted between signals from HYALMU and a Mexican ship named
Myalmo, so they decided to use only the first letter of each name and identified
their station as HAM. In the early pioneer and unregulated days of radio,
amateur operators picked their own frequencies and call letters. Then, as now,
some amateurs had better signals than some commercial stations. The resulting
interference finally came to the attention of Congressional Committees in
Washington and they gave much thought to proposed legislation designed to
critically limit amateur activity. In 1911, Albert Hyman chose the controversial
Wireless Regulations Bill as the topic of his thesis at Harvard. His instructor
insisted that a copy be sent to Senator David Walsh, a member of the committee
hearing the Bill. The Senator was so impressed that he sent for Mr. Hyman to
appear before the Committee. Hyman was put on the stand and described how the
little amateur station, HAM, was built, and he almost cried when he told the
crowded committee room that if the bill went through, they would have to close
up the station because they could not afford the license fees and other
requirements which were set up in the Bill. The debate started and the little
station, HAM, became a symbol of all the little amateur stations in the country
that were crying out to be saved from the menace and greed of the big commercial
stations who didn't want them around. Finally the Bill got to the floor of
Congress and every speaker talked about the poor little station, HAM. That's how
it all got started. You can find the whole story in the Congressional Record.
Nationwide publicity identified the station HAM with amateurs. From that time to
this, and probably to the end of time, in radio, Every amateur is a
ham.
"What is Amateur Radio?”
It's the most fun you can have with a radio. It's
a way to talk to people around the world, or even orbiting the world; to send
e-mail without any sort of internet connection, and to keep in touch with
friends while you're driving around town. But it's also a very important
communications system -- when cell phones don't work, regular phones don't work,
the internet doesn't work, ham radio works. When other systems are down or
overloaded, ham radio still gets the message through. Ham radio is a “hobby” –
that’s the fun part that gets most people interested and keeps them on the air.
But it's also a “service” -a vital service that has saved lives again and again
when regular communication systems failed.
"What is ham radio? It's the world's greatest
hobby that can save lives. It's a hobby that instantly turns into a life saving
service whenever there's a disaster or large-scale emergency. On September 11th,
it was ham radio that kept New York City agencies in touch with each other after
their command center was destroyed. When hurricanes like Katrina, Rita and Wilma
or tornadoes or floods knock out other communications, ham radio provides vital
life-and-death capabilities. But 99% of the time, hams do what they do because
it's just plain fun.
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 enjoy experimenting in wireless
digital communications. Those with a competitive streak enjoy "DX contests,"
where the object is to see how many stations 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 / A Bright Future:
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.
Amateur Radio today has come a long way from these
beginnings. Hams have their own satellites, chat with space stations, bounce
signals off the moon and are at the cutting edge of many technologies.
Computers, digital systems, slow scan television, cross-band repeaters and
concepts undreamed of just a few years ago are common in the ham community.
While skills in Morse code are no longer required by the FCC to get a license,
many hams still enjoy and use this older mode. But while the Morse code key may
be on the desk, it is probably next to a modern, transistorized system capable
of operating under the most extreme emergency conditions.
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. That's the AM commercial radio
band. 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 ten 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. Some of
these ten bands are very small and some are rather large. 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.
