One of the largest HF contests of the year, the CQ World Wide WPX Contest – SSB, runs from 0000 UTC Saturday, March 29 through 2359 UTC Sunday, March 30. Participants may operate on the 1.8, 3.5, 7, 14, 21, and 28 MHz bands. The exchange is your signal report and a sequential contact serial number starting with the numeral 1. Single Operator stations may operate 36 of the 48 hours, and off times must be a minimum of 60 minutes, during which no QSO is logged. Multioperator stations may operate for the entire 48-hour contest period. For full rules and scoring details, see www.cqwpx.com.
