Contest History
The contest is run each year in memory of the late John Moyle who was a long term editor of the Wireless Weekly, (later Radio & Hobbies - later Radio Television & Hobbies) from 1947 until his untimely death in 1960.
He served in the RAAF with distinction and was responsible for a number of innovative solutions to keeping radio and radar equipment working under difficult wartime and working conditions.
The WIA decided that a suitable long term memorial to John Moyle would be a Field Day with a focus on portable or field operation. The contest has been conducted annually ever since.
The rules of the contest have gradually changed over time and are still revised regularly.
The contest is still for portable or field operators, though Home stations can of course take part using a different scoring system.
Though Multiple Operators and club stations are actively encouraged to take part in the contest they are not competing against the single operator stations and in effect there are two separate contests run at the same time. Hence single operator stations take part in their own contest against other single operators.
Starting in 2026 the contest log checking process has moved to vklogchecker dot com. With the move the contest committee needed to revise and update the rules to be suitable for electronic log checking.
Upcoming Contest Date & Time
The next Field Day will be held over the weekend of the 21st-22nd March 2026 and will run from UTC 0100 on the Saturday to 0059 on the Sunday. (24 hours)
