Cleaned Logs for ARRL DX CW and SSB Contests, 2018

Cleaned versions of the logs for the ARRL DX CW and SSB contests are now available for 2018.

Links to the cleaned logs may be followed here.

The cleaned logs are the result of processing the QSO: lines from the entrants' submitted Cabrillo files (as [gratuitously] modified by the ARRL) to ensure that all fields contain valid values and all the data match the column-specific standard format for this contest.

Any line containing illegal data in a field has simply been removed. Also, only the QSO: lines are retained, so that each line in the file can be processed easily. All QTH multipliers are rendered as two letters, and the power is rendered as four digits, regardless of how the submitted log recorded these two fields; this should simplify processing the logs by scripts or programs, as should the use of fixed-length records in these cleaned files.
