Plain-language answer: ADIF is a standard format used to exchange amateur-radio contact records between logging programs and online services.
Why it matters
It preserves structured fields such as callsign, date, time, band, frequency, and mode, but programs may support different ADIF versions or optional fields.
Use it well
Export a small test file, inspect key fields, import it into the destination, and retain the original log and backup.
The common mistake
Assuming every custom field or submode survives every import unchanged.
Authority and safety boundary
Current regulations, electrical codes, equipment manuals, program authorization, and the served organization’s procedures control. This article is practical orientation, not permission to transmit, alter protective wiring, or self-deploy.
