About QSO Merge Bench.
QSO Merge Bench compares two ASCII ADI logs in your browser. It finds contacts worth reviewing and gives you control over each merge.
Review, then export
Matching callsign, band, mode, submode and time window identify candidates, not confirmed duplicates. Review every conflicting field before merging, or keep both contacts. Undecided candidates retain both records. Source files are never rewritten.
The exported ADI is a new copy. Its companion manifest records source mappings, merge decisions and discarded conflict values. Read the preservation policy and supported ADIF subset before importing a valuable log.
Evidence and limits
The parser follows a bounded subset of the cited ADIF specification. Synthetic fixtures test structural parsing, matching and export conservation. That does not establish compatibility with every logger or validate award eligibility. Review the new file in your own logging software and keep your originals.
