#CQ WW DX
CQ WW DX is one of the largest worldwide HF contests, held every year in an SSB weekend in October and a CW weekend in November. Stations exchange a signal report and a CQ zone, and countries and zones count as multipliers on each band. The contest has its own rules on categories, operating time, off time and log submission, which are published by the organizers and can change. Articles under this tag explain how to prepare, how to operate and how to check and send your log. Always confirm the details in the current official rules before you plan your entry.
