First amateur microwave allocation

In California, volunteers save lives as part of their involvement in an emergency communications network. And at the scene of a traffic accident on a Chicago freeway, a ham calls for help by using a pocket-sized hand-held radio. This unique mix of fun, public service, and convenience is the distinguishing characteristic of amateur radio. Some hams are attracted to the idea of communicating across the country, around the globe, and even with astronauts on space missions.

During this annual two-weekend contest, microwave enthusiasts take their radios outside to make contacts with one another, frequently from the tops of mountains due to the line-of-sight nature of microwaves. These contacts are usually voice single-sideband suppressed carrier or CW Morse Code. Points are awarded for a combination of distance between contacts and number of unique call signs collected. Most activity occurs in the 10 GHz band, but extra points are awarded for any higher bands used including lightwave communications! This enables the first-timer to get on the air and experience microwave radio first hand. There are a number of clubs around the world whose members are more than willing to help out newcomers to the hobby.

Amateur radio frequency allocation is done by national telecommunication authorities.

Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license.
