Accurately Copying Callsigns Can Make a Difference in Contest Outcomes

At the end of the 2019 CQWW SSB contest, K3LR and W3LPL, the two most prolific U.S. stations in the Multi-Operator / Multi-Transmitter category, were nearly tied.

Check your email archives to see if the contest organizer sent you a log check report (LCR), or visit the contest sponsor’s website and request a copy of your LCR. In addition to the percentage of calls that you busted or were assigned NIL, you
