Additional Information

  • Off Time Requirements

    Single Operator stations may operate up to 24 hours out of the 30-hour contest period. Multioperator stations may operate the entire 30 hours.  See "Special RTTY Roundup Rules" in the complete rules document.

    Following the first QSO, up to 6 hours of off-time may be taken in one or two breaks before the final QSO is logged.  Each off-time must be at least 30 minutes long.  Breaks shorter than 30 minutes or following the first two off-times are ignored. After 24 hours of operating time has been reached, Single Operator stations may continue to make and log QSOs but they will not count towards the final score. 

    The intent of the "two break" rule is to add another element of strategy to the contest. By limiting off-time to no more than two blocks, you can't take a bunch of short breaks. You have to decide based on local propagation, need for sleep, etc.  Only 24 hours of the 30 hours count towards your score. 
    Between the time you make your first QSO and the time you make your last QSO, you may take at most two off-times which must consist of at least 30 QSO-free minutes or they will not be counted as off-time. The time before your first QSO and the time after your last QSO don't count as these two off-times. 
    These examples satisfy the rules:
    - start at 1800 Sat and operate 24 hours straight
    - start an hour late at 1900, take 2 two-hour breaks, end at 2300 one hour early
    - start at 1800, operate 12 hours, sleep 5.5 hours, finish at 2330 one half-hour early
    If you take several 30-minute off-times, even if they total 6 hours or more, only the first two will be counted toward the 6 hours of required off-time.
    The log checking process will only check your QSOs and calculate your score over the first 24 hours of operating. You are encouraged to continue operating if you like - there won't be any penalty for doing so and those QSOs will count for the other operators. Don't delete any QSOs after the 24-hour limit so the other stations get credit for your contact.
