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. See the section Amateur Radio Bands for a more complete description of the band plans.
• 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. Using features such as URL or IRLP on a local repeater a ham in Toronto can talk to one in Vancouver or even Australia using a simple hand-held transceiver.
  
  

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. This is one radio "band." There are other bands of radio spectrum for amateur, government, military and commercial radio uses. If you could hear the many different bands, you would 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 26 bands (i.e., specific groups of frequencies) spaced from 1.8 Megahertz, which is just above the broadcast radio frequencies, all the way up to 275 Gigahertz! Depending on which band we use, we can talk across town, around the world, or out to satellites in space. Hams can even bounce signals off the moon!

So what are the bands that most Radio Amateurs use? The table below shows bands that are relatively common and how and when they are in use. Again your license will determine which bands and what portions you are eligible to use.

	Band (meter)	MHz	Use*
HF	160	1.8 - 2.0	night
	80	3.5 - 4.0	night and local day
	40	7.0 - 7.3	night and local day
	30	10.1 - 10.15	CW and digital
	20	14.0 - 14.350	world wide day and night
	17	18.068 - 18.168	world wide day and night
	15	21.0 - 21.450	primarily a daytime band
	12	24.890 - 24.990	primarily a daytime band
	10	28.0 - 29.70	daytime during sunspot highs
VHF	6	50 - 54	local to world-wide
	2	144 - 148	local and medium distance
UHF	70 cm	430 - 440	local

Why Do You Need 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 during emergencies. 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.
