It's
a hobby:
In its day to day existence, amateur radio is a hobby. How in depth a hobby
depends on each operator's personal interests. For some, being able to talk
to people around the world is their only goal. For others, they want to build
the radios and antennas from scratch--some times for fun; some times in an effort
to make a better device.
The hobby of amateur
radio crosses into other areas. One science area developed by amateur radio
operators is Radio
Astronomy. The wireless computing we see today has its roots in the packet
radio amateur radio operators developed in the mid-1960's.
Hobbyist areas
of use and experimentation amateur radio covers include:
- Point-to-point

universities.
Licensing
currently has 3 levels:
- Technician -
A 35 question test must be passed. No Morse Code ability required at this
level.
- General - a
35 question test must be passed. Ability to understand 5 words per minute
of Morse Code is required.
- Extra - a 50
question test must be passed. No Morse code needed since ability already
shown to pass the General level
ARRL
The American Radio Relay League is a national membership association for amateur
radio operators. It was founded in May 1914 and today has a membership around
163,000. The ARRL promotes interest in amateur radio communications and experimentation,
represents US radio amateurs in legislative matters, and maintains fraternalism
and high standard of conduct among amateur radio operators. The ARRL publishes
a monthly journal QST, as well as newsletters and many publications
covering all aspects of amateur radio.
With the areas
of interest Amateur Radio covers, people from many different walks of life
become licensed. Majors at MTSU that would have a direct or indirect interest
in amateur radio:
- Recording
- Radio/TV
- Computer Science/Engineering
- Education
- Electrical Engineering
- Physics/Astronomy
- Aviation/Aerospace
- Math
- Mechanical Engineering
It's more than just a hobby:
In the United States, Amateur Radio is regulated by the Federal Communications
Commission. The FCC via the
Code of Federal Regulations Title 47, Chapter I, part 97 defines the radio
frequencies, the maximum amount of power useable, the types of activity allowed
and expected, and the methods for becoming licensed. When necessary
United States Code Title 47, Chapter 5 is the primary source for addressing
violations of Part 97.
The U.S. Congress
on two occasions has shown support for the Amateur Radio Service and the public
services the operators provide -- Public Law 100-594
and 103-408.
Part of these Public Laws is the suggestion that all levels of government
support and encourage Amateur Radio operation.
A common call
put out to amateur radio operators is to serve as a means of communications
during emergencies, natural disasters, and man-made disasters. Part
97.1(a) actually makes Emergency Communications the primary function of
the Amateur Radio Service with the hobby aspect secondary. This responsibility
of service is attributed to why maintaining a Amateur Radio License in the
United States has no fee or tax to the licensee. Only recently with the advent
of operators being able to request vanity call signs that a yearly fee has
been enacted. This small fee is only for operators who request a vanity call
sign.
There are over
600,000 licensed
amateur radio operators in the United States and many sign up with ARES/RACES
to supply time and equipment and be trained for when the activation call goes
out. Many more that come out of the woodwork when disaster strikes.
On June
21, 2003, the American
Radio Relay League (ARRL) began its official affiliation with the Citizen
Corps and the Department of Homeland Security. Citizen Corps Liaison to the
White House Liz DiGregorio called amateur radio operators the "first of the
first responders" at the formal Statement of Affiliation signing. This
affiliation is one
of many the ARRL has. Other organizations the ARRL has offical affiliations
with include the American Red Cross, National Weather Service, National Communications
System, and the Salvation Army.
Many agencies
which have an active part of disaster operations and recovery have amateur
radio operators embedded in their operations or have part of their disaster
plan covering how to incorporate amateur radio operators if normal communications
channels fail or become overloaded.
ARES/RACES:
ARES (Amateur Radio Emergency
Service) is an ARRLsponsored
organization. Public service communication has been a traditional responsibility
of the Amateur Radio Service since 1913. The ARRL
provides a manual of standards and procedures -- Public
Service Communications Manual. When there isn't an emergency, besides yearly
practice drills and monthly training sessions, ARES groups will often serve
as communications support for events like parades, walkathons, and bicycle rides.
RACES
(Radio Amateur Civil Emergency Service) was founded 1952 as an update to the
FCC regulation
of the Amateur Radio Service. It's purpose was to provide volunteers to serve
in government agencies as the means of communications during times of extraordinary
need. FEMA (Federal Emergency
Management Agency) provides planning guidance and technical assistance for
establishing a RACES organization at the state and local government level.
Part of this assistance is given in a standard operating procedure manual
-- Guidance
for Radio Amateur Civil Emergency Service.
The ARRL encourages
volunteers to be members of both organizations.
Events
many remember and ARES/RACES was utilized:
MARS:
MARS (Military Affiliate Radio System) is a Department
of Defense sponsored program. The program consists of licensed amateur radio
operators who are interested in military communications on a local, national,
and international basis as an adjunct to normal communications. The Army,
Air Force,
and Navy-Marines-Coast Guard
each have their own MARS network, but the mission of each is the same. MARS
history began in 1925 with the Army. In 1948, MARS became a join effort
between the Army and Air Force. In 1962, the Navy-Marine Corps MARS program
was launched to make MARS a joint service mission.
The mission:
- To provide Department
of Defense sponsored emergency communications on a local, national, and
international basis as an adjunct to normal communications.
- To provide auxiliary
communications for military, civil, and/or disaster officials during periods
of emergency.
- To assist in
effecting normal communications under emergency conditions.
SKYWARN:
SKYWARN was started in the 70's. While it is not necessary to be a licensed
amateur radio operator to participate, the majority of SKYWARN spotters are
amateur radio operators. Spotters serve as the eyes and ears of the National
Weather Service via SKYWARN.
While Doppler radar will give the hint of a tornado, it is often a SKYWARN spotter
which verifies its existence. Through spotter ground truth data, warnings or
alerts are often given or verified. The anonymous reports of hail, rain amounts,
and wind speeds the NWS provides to mass media weather forecasters are often
provided by amateur radio operators which either live in the area for which
they are reporting or when SKYWARN is activated, driving around giving regular
reports.
Why do we need amateur radio during a disaster,
we have cell phones?
A common question from non-'amateur radio operators' is "why do we need amateur
radio operators during a disaster these days, we have cellular phones?" Flexibility
would be the easiest answer because depending on the disaster electricity, land
based phone lines, and cellular phones could be disabled or crippled for days
to weeks.
Cellular phones
work by having an autonomous tower with antennas which services an area. The
size of the area depends on how many people the cellular phone company expects
to be servicing in a given area and the terrain of the service area. When
the cell tower no longer has electricity to power it, the antenna takes enough
damage, or the tower falls that "cell" then has no services provided within
it. Also, depending on the cellular tower, it will connect to the home office
via microwave antenna or land line. If the method the cell tower uses to connect
to the world is disabled, so is the cell tower.
Cell towers are
vulnerable to the same elements which will disable land based phone lines.
- Wind
- Winds over
120MPH will cause common cell towers to fall
- Power Failure
- If the electricity
to the cell tower fails, the tower fails
- In some
areas, a precentage of cell towers have backup generators
- Generator
fuel tanks are only large enough to have fuel for a couple days of use
- Lightning
- Can melt a
cell tower to the ground
- Even a near
miss of the cell tower can cause disruption in services via the localized
EMP caused by lightning
- Flood
- Water in the
tower electrical system will disable it
- Violent flood
waters can topple the cell tower
- Wildfire
- The heat of
a wildfire can disable the electronics of a cell tower
- The heat of
a wildfire can weaken the tower structure so it falls
- Terrorism
- As we saw
on 9/11/01, some times the building with the cell tower on it falls
- Cellular communication
is a potential target
While there is
no doubt cellular phones play a part in emergency communications, they do
not replace the flexibility of amateur radio equipment to be able to facilitate
communications under extreme conditions. From being able to use just a length
of wire as an antenna to being able to put out the signal power equivalent
to a small FM rock radio station, amateur radio operators can carry out point
to point communications when every other common form of radio or land base
communication have been disabled. This includes being able to have the point
to point locations on opposite sides of the globe.
