Out of curiosity, I tested importing Cabrillo and experienced most often issues during load. Complete SDC crashes, or dates that were not the original date, or data not properly inserted in the fields (when using different contest profiles). Cabrillo requirements seem to depend on the specific contest and with DXLog as profile I was not able to get anything loaded from sample cabrillo files.
For DXLog I was extracting parts of my log in DXKeeper with mode CW and selected in DXKeeper one the format for CQ WW CW.
With Cabrillo logs from old contests it worked often loading into this specific SDC Contest format, but as mentioned in the best case with some date issues in the log in SDC.
It would then also be nice to be able to recalculate the contest to get some of the calculated fields populated. Nice to have would be to get an ADIF import with recalculation feature.
