## What is Ham Field Log?

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
