More Facts

Field Day is an annual amateur radio exercise, widely sponsored by IARU regions and member organizations, encouraging emergency communications preparedness among amateur radio operators. In the United States, it is typically the largest single emergency preparedness exercise in the country, with over 30,000 operators participating each year. Field Day is always the fourth full weekend of June, beginning at 1800 UTC Saturday and running through 2059 UTC Sunday.

Since the first ARRL Field Day in 1933, radio amateurs throughout North America have practiced the rapid deployment of radio communications equipment in environments ranging from operations under tents in remote areas to operations inside Emergency Operations Centers (EOCs). Operations using emergency and alternative power sources are highly encouraged, since electricity and other public infrastructures are often among the first to fail during a natural disaster or severe weather.

To determine the effectiveness of the exercise and of each participant's operations, there is an integrated contesting component, and many clubs also engage in concurrent leisure activities (camping out, cookouts, etc.). Operations typically last a continuous twenty-four hours, requiring scheduled relief operators to keep stations on the air. Additional contest points are awarded for experimenting with unusual modes, making contacts via satellite, and involving youth in the activity

Emergency Preparedness
Field Day stresses emergency preparedness. Frequently, entire radio clubs get involved and assemble a portable radio station in a field or park. Some might use quickly deployable portable antennas while other might erect more elaborate radio masts and towers supporting several antennas. Generators or solar power provide electricity to amateur radio transceivers, which may be located in tents, cars, recreational vehicles, or other portable shelters.

Contest Activity and Rules
The contest aspect of a Field Day operating event is to contact as many stations as possible in the given time period (twenty-four hours, during a weekend, if setup commences before the contest starts, or 27 hours if setup commences at contest start time) using the portable station. Each station will exchange information with other participating stations. For the North American Field Day, the exchange consists of the station call sign, the name of the ARRL-recognized section from which the station is operating, and a class designator which indicates the number of transmitters concurrently used at the station and information about the type of electrical power source being used.

The contest portion of Field Day has two purposes. The primary purpose is to demonstrate the group's ability to plan operations that can be effective for an entire twenty-four-hour period, including operator endurance and adequate numbers of operators for a shift operation. The secondary portion is to demonstrate the technical proficiency of the station that has been hastily constructed for the purpose; in theory a better station will be capable of emergency operations in more dire conditions. Such a station will also be capable of making more contacts during the contest portion of Field Day.

The rules governing this activity are published by the sponsor of the particular Field Day exercise.

Promotion of Amateur Radio
Field Day is frequently used to attract significant publicity for amateur radio, and some clubs simultaneously demonstrate technologies including single sideband voice, Morse code, digital modes (such as RTTY, PSK31, and Winlink, among others), and communication via amateur radio satellite.
