B. Single Operator Overlay Categories: Any Single Operator entrant who meets the requirements may ALSO enter one of the categories shown below by adding the appropriate CATEGORY-OVERLAY line in the Cabrillo log file header. Overlay category entries will be listed separately in the results, scored as All Bands, and grouped by High Power and Low Power (includes QRP).
3. Classic Operator (CLASSIC): The entrant will use only one radio and may operate up to 24 of the 36 hours – off times are a minimum of 60 minutes during which no QSO is logged. If the log shows more than 24 hours of operation, only the first 24 hours will be counted for the overlay score. Use of QSO alerting assistance of any kind is prohibited (see rule IX.B) for the duration of contest. Receiving while transmitting is also prohibited.
