Rules, ARRL Field Day

Contests · General Rules · Field Day Contest Forms

1. Eligibility: Field Day is opened competitively to all amateurs in the ARRL/RAC Field Organization (plus Yukon and Northwest Territories). Foreign stations may be contacted for credit, but are not eligible to compete.

2. Object: To work as many stations as possible on any or all amateur bands (excluding the 30, 17, and 12-Meter bands) and, in doing so, to learn to operate in abnormal situations under less-than-optimum conditions. A premium is placed on skills and equipment developed to meet the challenge of emergency preparedness and to acquaint the public with the capabilities of Amateur Radio.

3. Date and Field Day Period: Always held on the fourth full weekend of June. Begins 1800 UTC Saturday, ends 2100 UTC Sunday (June 26-27, 1999).

4. Entry Categories: Field Day entries are classified according to the maximum number of simultaneous transmitted signals, followed by the designation of the nature of the individual or group participation. Below 30 MHz, once a transmitter is used for a contact on a band, it must remain on that band for at least 15 minutes. During this 15-minute period, the transmitter is considered to be transmitting a signal, whether it is or not, for the purpose of determining transmitter class. Switching devices are prohibited.

5. Exchange: Stations in any ARRL/RAC Section will exchange their Field Day operating class and ARRL/RAC Section. For example, if your club group was planning to operate in the three-transmitter, Class A category from Missouri, you would send "3 A Missouri." Foreign stations send RS(T) and QTH.

6. Miscellaneous Rules:

7. Scoring: Scores are based on the total number of valid contact points times the multiplier corresponding to the highest power used at any time during the Field Day period, plus bonus points.

8. Reporting: Entries must be postmarked by July 27, 1999. No late entries can be accepted. A complete entry consists of an official ARRL summary sheet (or reasonable facsimile) and a list of stations worked on each band/mode during Field Day, plus bonus proof. The list of stations worked on each band or mode may take the form of official ARRL dupe sheets (Adobe Acrobat file, 83,828 bytes) or an alphanumeric listing of call signs worked per band and mode. This list may be computer-generated. Incomplete or illegible entries will be classified as checklogs. A copy of Field Day logs should be kept by your Field Day group, but should not be sent in unless specifically requested later by ARRL.

9. Other: See general rules for All ARRL Contests.
