Ham Field Log

Check callsigns, duplicates, RST, and activation reference before leaving the site, then export clean ADIF offline.

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
