Field day

Related Wiki pages: Contesting

North America

Field Day is de-facto one of the premier amateur radio contests in North America. It is held on the fourth full weekend in June, and lasts approximately 24 hours.

The event is promoted by ARRL as an emergency-readiness exercise and as a way to promote amateur radio to newcomers in the US and Canada. Nominally a Field Day is not a contest, but an exercise: an event in which participants are encouraged to employ portable, temporary or alternate-power facilities in order to promote the skills useful to rapid deployment of emergency communications in response to a disaster.

There are a number of different categories in which Field Day contestants can compete. These include A (groups of three or more operators, usually clubs), B (one or two people), C (mobile stations, usually attached to vehicles), D (home stations running on regular wall outlet power), E (home stations running on emergency power, such as batteries, wind, or solar), and F (Emergency Operations Centres).

Australian Field Days

A number of Australian clubs run local field days. In addition to these, the following national field days are run in Australia:

John Moyle Field Day

This event is run every year, in the third weekend of March, in memory of John Moyle who was the editor of Wireless Weekly (Radio, Television and Hobbies) from 1947 to 1965. The Wireless Institute of Australia decided to honour his work in radio with the annual field day that carries his name.

The contest is primarily for portable and field operators, however home operators can take part, using a modified scoring system, and is open to VK, ZL and P2 operators.

Contest rules and scoring system can be found here.

VHF - UHF Field days

The aim of these field days is to encourage activity on VHF and microwave bands in portable stations. Home stations are encouraged to participate in a separate category.

There are no mode restrictions, but all contacts must be in simplex, with no repeater use permitted. In general, FM and SSB have proven to be the most popular modes used during these field days.

Scoring is based on grid squares "captured" during the contest.

Further information about these field days can be found here.

Winter field day

The Society for the Preservation of Amateur Radio promotes a Winter Field Day, which normally falls in late January (well within the coldest portion of North America's winters). While this event is smaller and less well-known than the main ARRL field day in June, it is conducted annually as an exercise "to encourage emergency operating preparedness in the winter" by operating for twenty-four hours (starting noon EST/GMT-5) on all bands (except WARC) and all modes.

Stations are categorised by number of operators (1, 2, Multi) and site type (Indoor, Outdoor, Home). An indoor site is defined as a location (such as a community centre) which normally does not house an operational fixed radio amateur station; station set up may begin no earlier than 8:00 AM EST (1300 UTC) on the day of the contest. A 'home' site is an existing fixed station. An outdoor site includes RV's, mobile stations, campgrounds or other locations without permanent walls and structures.

Exchange is callsign, true RS/T (not all 599), category and local outside temperature (with F or C). For example 1 person from a campground where the temperature is 28 F might send "KX5XYZ 449 1O 28F" or "KX5XYZ 449 1O -2C".^[1]
