Dupe is not a suggestion
Band/mode/call identity at type speed. The network pileup does not get a second QSO.
ARRL Field Day
Field Day logging that does not collapse at 1800Z.
Log73 is built for the weekend the whole service shows up. Class, section, DUPE, rate, multi-station sync, and a Cabrillo that the robot accepts.
Class and section on the line
Exchange fields that operators can shout, not a spreadsheet column hidden behind a menu.
Bonus-aware ops
Satellite, natural power, and public-info notes live next to the log, not on a paper checklist in the kitchen tent.
From FD back to POTA
Monday morning you are an activator again. Same OS, same muscle memory.
Questions
Does Log73 export Cabrillo for Field Day?
Yes. Cabrillo and ADIF from the device, including after an offline weekend.
Can multiple stations share a dupe sheet?
On-site sync when a LAN or hotspot exists; otherwise merge from snapshots without destroying either log.
