Cabrillo refers to a universal log submission format for electronic logs that is widely used by all major contests.

There are two versions of the Cabrillo log file format. The WW Digi DX Contest accepts both Cabrillo v2 and v3 format files. One of the major changes from v2 to v3 was in the way categories are specified. We strongly request that you submit logs using the Cabrillo v3 format if possible.
