Eligibility: All licensed amateur radio operators are encouraged to participate. Radio operators in the United States and Canada will use the designated location identifiers set up by the ARRL and RAC field organizations. Operators in Mexico will use MX as their location identifier, and all other operators outside of North America will use DX as the location identifier. All participants are encouraged to submit a log of stations worked.

Objective: To set up an amateur radio field station and successfully make multiple contacts. Successful participants are those who can set up their equipment and correctly log the designated exchange during the operational period explained below.

The 24-hour operational period starts at 1900 UTC on Saturday, the 28th and ends at 18:59 UTC on Sunday, the 29th. Stations may begin setting up no earlier than 19:00 UTC on Friday before. However cumulative set-up time shall not exceed 12 hours.
