About
Contest Objective: To work as many amateur stations as possible via the earth-moon-earth path on any authorized amateur frequency above 50 MHz.
NEW: Rule changes for 2024:
Effective in the 2024 event, the contest exchange will now be a station's four-digit Maidenhead grid square locator. The grid square now also serves as the score multiplier, replacing US states, Canadian provinces, and DXCC entities as the multiplier. Analog stations may optionally send a signal report in any mutually understood format if station size or propagation prohibit grid squares from being exchanged. See the "Cabrillo Log Examples" section for examples of logging contacts.

In order for proper scoring of the multipliers in the event, it is important that your log include the four digit grid square from which the QSO was made from. A station's 4-Digit-Grid-Square must be reported as part of the submitted Cabrillo log on each QSO line regardless of what type of exchange was received by the other station. Portable stations who paper log, should indicate which QSOs were made from which grid square. See the following QSO lines as examples below.
