The 2-Meter Amateur band frequencies are reserved for the exclusive use of those licensed in the United States by the Federal Communications Commission (FCC) as Amateur Radio Operators or "Ham Radio Operators". Ham radio operators use the 2-meter band for general conversations as well as for emergency communications. Ham radio operators are often the first called upon to assist in major disasters with communications between the public and emergency services such a law enforcement, fire and emergency medical services. The American Red Cross has recognized that the 2-Meter Amateur band is a very effective way of providing communications during times of emergency and Ham radio operators provide 90% of the coordination efforts during a major emergency. During an emergency a 2-Meter band receiver could save your life or that of a loved one.

How does the 2-Meter Amateur Radio Band work?

In most communities, the local Ham radio operators own and maintain repeaters on the 2-meter band, which assists their communications by increasing the distance that they can communicate with each other while still maintaining the quality of an FM transmission. These repeater stations are located in high locations such as mountaintops or tall buildings in the big cities and consist of a powerful transmitter and a high-gain antenna allowing Ham operators to extend their coverage areas, often as much as 200 miles or more. These stations often have alternative forms of power such as generators, solar power and batteries, which keep them in operation when the commercial power supply has been discontinued due to weather or other disasters. Individual ham operators have also found alternative power sources for their equipment so that they can operate even when there is no commercial power available.

Ham radio operators are very inventive in their approach to communications and can often find a way to communicate when normal communications such as cell phones have been interrupted. As an example, Ham radio operators have been able to make phone calls using the 2-meter band for many years before the invention of the cellular telephone.

What is the 2-Meter Amateur Radio band anyway?

According to Wikipedia, "The 2 meter amateur radio band is a portion of the VHF (very high frequency) Spectrum, comprising of frequencies stretching from 144.000 MHz to 148.000 MHz." These communications are generally FM or frequency modulated transmissions although some operators do operate using SSB (single sideband) or CW (Morse code). These modes of operation allow for longer distance communications without the use of repeater stations.
