Ham Field Log is built for portable amateur radio operators who need a field-ready QSO log when signal is weak or unavailable, then a quick ADIF closeout check before leaving the activation site. Start one session per POTA, SOTA, or field-day activation, keep the activation reference visible while you log, check callsigns, duplicates, RST reports, operator callsign, and reference before export, then hand off a clean ADIF file when the trip is done. Best for: - POTA activators - SOTA operators - field day and portable outings - offline backup logging on iPhone What it does: - log QSOs without signal, login, or later notebook re-entry - keep each activation in its own session with visible POTA/SOTA reference context - save contacts quickly with band and mode presets - check duplicate callsigns before export - confirm operator callsign, activation reference, contact callsigns, and RST reports before leaving the site - review the session with a clear ADIF closeout status - export a clean ADIF file for desktop logbook import after the activation - keep your log stored locally on your iPhone
