WHAT HAMS DO?

Whether you would like to chat with your friends on the way to work or
school, check into a net to discuss topics of a mutual interest, or volunteer
for emergency services, amateur radio is first and foremost about
communication. With hams that means two way communication by radio. Radios can
be hand-held transceivers similar to a walkie talkie, a mobile unit for use in
a car or other vehicle, or a base station with an outdoor antenna used for
local or distance communication. Regardless of the type of equipment radio
amateurs have a wide range of activities they can pursue. Some of these are:
- Talking with friends
within the local community using a hand-held transceiver (HT) on VHF (2
meters) or UHF (70 cm.). You can extend your HT range up to 50 miles or
more by transmitting through a local repeater.
- DXing. DX means
distance communication and with the right equipment worldwide
communication on the HF bands (10 through 160 meters) is a regular
possibility.
- Assisting with emergency
and disaster communication. Organizations in the amateur community
such as the Amateur Radio Emergency Service (ARES) and the National
Traffic System (NTS) prepare amateurs with the training needed to assist
in emergency situations.
- Technical experimenting.
Hams come from all walks of life ranging from technicians to engineers,
teachers to scientists, and students to retirees. For many of them
the attraction to the hobby is to build their own equipment whether it is
just a simple antenna, something as complex as a transmitter, or an
interface between their radio and a computer.
- Contesting. Contesting
is often called the "sport" of ham radio. Almost every weekend
there is some form of amateur radio contest. Hams get on the air and
compete to see who can make the most contacts in a limited period of time.
- Talk to an astronaut. Yes, it
is really possible. Space stations do have ham radio equipment and
licensed ham astronauts take the time to make contacts with amateurs on
earth. Hams also have satellites where you can bounce a signal to
communicate with other hams on earth.
- Use digital communication.
Connect a computer to your radio and install some software and you can be
communicating digitally over the air. Some of these digital modes can be
more effective in marginal transmission conditions and some even sport
error free transmission.
- Internet
communication. Using some of the latest technologies hams can supplement a
modest station with Internet connections.
