MICROWAVE CHALLENGE – JANUARY 2011
The Summer Field Day for 2011 will include a “Microwave Challenge”, with special certificates to be awarded to the participants on microwave bands.
Contest Introduction
The VHF-UHF Field Days provide VHF-UHF operators with the opportunity to "head for the hills" and see how far they can work.
The Field Days have separate sections for single and multiple operator stations. The duration of the Field Day is 24 hours, but there are also 8 hour sections for operators who may not be able to camp overnight. Most club stations prefer to operate for the full 24 hours.
The Field Days also generate plenty of activity from home stations, so there is also a separate Home Station section.
The scoring is based on grid locator squares. Each new square worked gives quite a boost to the score, and this encourages the entrants to operate from locations in grid squares that normally don't have a great amount of amateur activity.
There are no mode restrictions, except that all contacts must be simplex - contacts through repeaters or satellites are not allowed. There is plenty of FM activity, but one feature of the Field Days is a high level of SSB activity.
It is possible to do very well with only modest antennas if you pick a good hilltop. Another option, if your station is easily transportable, is to operate from more than one grid square during the contest period.
Aim Of The Contest
The overriding aim is to get away for the weekend and have fun! But next after that, the aims are:
 to encourage more activity on VHF and microwave bands;
to encourage people to work greater distances than usual by operating portable, and
to provide opportunities for people to activate or work into new grid squares.

Contest History
The first VHF-UHF Field Day was run as a trial in January 1989. It was quite well received so it has continued since then. In 1998, there was a trial Spring Field Day which also proved a success. Support for the Field Days has continued to increase, and a third event - the Winter VHF-UHF Field Day - was introduced in 2008.
Upcoming Contest Date & Time
Spring VHF-UHF Field Day - November 20/21

Contest Rules
The rules are available for download at the bottom of this page.
Contest Scoring
Field Day scoring is simple - one point per contact. But entrants also score 10 points for each different locator square worked, and each locator square they have operated from, on each band. There are also band multipliers to encourage activity on the higher UHF and microwave bands.
Full details of the scoring system, and a sample scoring sheet, are available in the "Files for Download" section.
Further Information on Maidenhead Locators
Each four-digit Maidenhead locator identifies an area which covers 1 degree of latitude and two degrees of longitude. Detailed explanation of the Maidenhead locator system can be found in the Download section below. Also available is a computer program that can convert latitude and longitude into grid locators, and vice versa.
An easy way to find your latitude and longitude from a Google map is to click this Link to the iTouch Map web site.
Submitting Your Log
Logs should be accompanied by a cover sheet including a scoring table as described in the rules. A sample scoring sheet is available for download at the bottom of this page. Logs can be submitted either on paper or as email attachments.
Paper logs can be mailed to the Manager, VHF-UHF Field Day, 3 Vernal Avenue, Mitcham, Vic 3132. Electronic logs can be e-mailed to vhf-contests@wia.org.au. Acceptable log formats include: ASCII text, RTF, DOC, DOCX, XLS, MDB, PDF, or any Open Document format.
