Cabrillo to ADIF — a contest log into your logbook or LoTW
Convert a Cabrillo contest log (.log, .cbr) to ADIF: every QSO with date, time, band, frequency, mode, reports and exchange, ready for LoTW, eQSL, QRZ, Club Log or your logging program. In your browser, nothing uploaded.
About this conversion
A Cabrillo file is what you send to the contest organiser — but LoTW, QRZ, Club Log and everyday loggers want ADIF. Drop the .log here and every QSO line becomes a QSO in ADIF: the date and time, the call, the band and the frequency in MHz, the mode, the RST both ways, the rest of the exchange in STX_STRING and SRX_STRING (and in STX and SRX when it is a serial number), your callsign as STATION_CALLSIGN and the contest as CONTEST_ID. X-QSO lines, which the organiser is told to ignore, are left out.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
The same log, other ways
The log stays open after it is read, so the format is picked at the end: the same file can leave here as ADX (.adx), Excel (.xlsx), CSV, JSON, POTA (.adi) or SOTA CSV (V2). Before that you can filter it by band, mode, year, country or QSL status and save only those QSOs.
Questions
- What happens to DG (digital) QSOs?
- Cabrillo says only that a QSO was digital, not which mode. Those QSOs get no MODE in ADIF and the page tells you how many there are — set the mode (FT8, PSK31…) in your logger before uploading to LoTW, which will not take a QSO without one.
- Is “5NN” kept?
- In ADIF reports are digits, so 5NN is written as 599 — the way LoTW and every logger expect it.
- Which files does it read?
- Cabrillo files from contest loggers and from the organisers’ web forms, whatever the file is called (.log, .cbr, .txt) — it is the START-OF-LOG line that counts. Odd lines are handled: a sent exchange longer than the received one, a transmitter number at the end, a band like “40M” instead of a frequency.
