#Contest Period

A contest has a fixed start and a fixed end in UTC, and QSOs outside this period are not valid for the contest. A wrong computer clock or a late QSO at the last minute can put a contact outside the period without the operator noticing. The articles under this tag explain how to prevent such errors and how to check the first and last QSOs of your log. Read the current rules of each contest for the exact times. A few minutes of attention can protect the valid QSOs.
