#Contest Logging
Contest logging covers everything between the first QSO and the file you send to the organizers. It includes setting up the logger, entering the right station details, keeping accurate times and exchanges, and exporting a clean Cabrillo file. Small mistakes at the logging stage tend to repeat in every line of the log, so they are worth preventing early. Articles under this tag explain good habits, common pitfalls and the checks to make before you submit. They are written for operators of all experience levels who use programs such as N1MM Logger+, DXLog and Win-Test.
