#Cabrillo
Cabrillo is the standard text format for submitting contest logs. A file has a header with fields such as CALLSIGN and CATEGORY, one QSO line for each contact, and an end marker. Most contest sponsors accept it, and every major logging program can export it. Mistakes in the header or in the QSO lines can lead to a log being rejected or placed in the wrong category. Articles under this tag explain the fields, show how to export the file from common loggers and describe what to check before you upload it.
