Cabrillo Log Format
Cabrillo refers to a universal log submission format created by Trey Garlough, N5KO. This is the preferred format for all electronic logs.
There are two versions of the Cabrillo log file format. The North American SSB Sprint Contest accepts both Cabrillo v2 and v3 format files. We strongly request that you submit logs using the Cabrillo v3 format if possible; v2 is deprecated and support will be dropped in the future.
