Q: Several of our club members are going to operate independently and wish to attribute their scores to the aggregate club score. What call sign should they use?
A: Participants should use their own call signs. Except for Class C (mobile) entries, all transmitters, receivers, and antennas must be located within a 1,000-foot-diameter circle may operate using a single call sign. This prohibits the use of a single call sign from more than one location. Under the 2020 waiver, those operating from home, including backyard operations, must use their own station call signs. Multiple home stations operating with a club call sign or modified club call sign, such as W1AW-1, W1AW-2, W1AW-3, etc, are not allowed.
Q: How does my club submit an aggregate club score? Does the club need to add up each participating member’s scores and submit a club entry with the aggregate score under the club call sign?
A: Each participant will submit his or her own independent entry under his or her call sign. ARRL will calculate the aggregate score based upon the club name entered on the official Field Day entry form via the web applet (preferred method) or on the paper Field Day entry form. In order for results to be tabulated correctly, all club participants must enter the club’s official name exactly the same, avoiding abbreviations or acronyms. This is important!
Q: Our group is still planning to operate at the usual Field Day site, but some members do not feel comfortable gathering in a large group this year. Can we still submit an entry using the club call sign, as well as have members operating from home using their own call signs?
A: Yes. If your club is still hosting a group Field Day effort, it will submit an entry as usual, using the club call sign. Club members operating at home will submit separate entries with their own call signs and will enter the club name on the entry form for club aggregate scoring.
Q: Can a club member operate from home using the club call sign?
A: Yes, but the call sign may only be used in one location. The member must receive permission from the trustee of the club call sign.
Q: Our club normally enters Field Day in Class A. If we operate from our home stations, in which class should individual members enter in order to be included in the aggregate club score?
A: Each member will operate independently and will submit the entry using whatever class that applies to their operation. Typically, home stations running on commercial ac power are Class D, while home stations running on battery, solar, generator, or the like (i.e., not from ac mains) are Class E. When the results are published, each club member will be listed in the results under the class in which they operated. For 2020 only, aggregate club scores will be listed by the club name in a separate listing.
Q: Our club will have 10 members operating from home as Class D stations. Should they worry about working the same station on the same band and mode (duplicates)?
A: Because members are operating as separate entries using their own call signs, the contacts are not considered duplicates.
Q: Does the club need to be an ARRL-affiliated club to participate in Field Day?
A: No. All clubs and groups are welcome to participate in ARRL Field Day.
Q: How will bonus points be calculated for the aggregate club scores? Can individual club members still earn bonus points?
A: All individual scores, including bonus points, will be added together to determine the aggregate club score. Refer to the complete rules to determine eligibility for bonus points. — Thanks to Paul Bourque, N1SFE, ARRL Contest Program Manager
