Park references, not paperwork
K- and VE- references, park names, and activation status live on the log line. Ten in-park QSOs is a number you can see, not a guess.
Parks on the Air
The POTA logger built for real activations.
Log73 is the offline-first tactical log for Parks on the Air activators and hunters. Capture QSOs at the picnic table, on a trail, or in the rain — then sync when you get signal.
Activator and hunter modes
Switch roles without switching apps. Hunters get spots and park hunts; activators get rate, DUPE, and a clean run screen.
GPS that survives the woods
Lock grid and park geofence from the phone GNSS even when cellular is gone. The log still writes.
Hunters hear you. You keep them.
Instant DUPE on band/mode so you never burn a pileup on a station you already have.
Questions
Does Log73 work for POTA without cell service?
Yes. Logging, GPS grid, park reference, and DUPE all run on-device. Sync and spots resume when you have a path.
Can hunters and activators share one log?
One operator, one log, two modes. Role switches are instant; ADIF export tags the activation correctly.
