The annual ARRL SSB November Sweepstakes will occur on Saturday and Sunday, November 16-17. The Sweepstakes offers an opportunity to achieve WAS in 24 hours or to earn a Clean Sweep mug. It is perhaps the most popular HF radio contest in the United States. The required exchange is rather long, including a consecutive serial number, a precedence (transmitter power, etc), your call sign, and your check (year of first licensing). The contest begins at 4pm local time, and entries must be submitted effectively by December 2.
