Tactical logging
Call, RST, grid, DUPE, and UTC at type speed. The log is a weapon, not a form.
03 — Tactical logging
Capture QSOs faster than pen and paper.
Call entry, UTC, RST, and DUPE on one line. The console is built for a pileup, a summit wind, and a glove. If you can type the call, the QSO is already written.

04 — Space weather intelligence
Let data choose the best band.
SFI, K-index, A-index, and the greyline are not a sidebar. They drive which band Log73 puts under your fingers next.

05 — AI decision engine
Know exactly what to work next.
Band openings, park hunts, and the next bird. The engine reads your log, the clock, and the ionosphere — then points.

06 — CAT control
Full radio control in your pocket.
IC-705, KX3, G90, FT-891. Frequency and mode belong to the radio. The log never asks you to retype what the VFO already knows.

07 — Satellite operations
Track the sky in real time.
ISS, AO-91, SO-50. AOS, TCA, LOS, footprint, and a SAT-mode log that LOTW accepts without a second editor.

Built for places without internet.
Local storage is the source of truth. Recovery snapshots survive a dead battery. Sync is a replica you turn on when you get a path.

10 — Platform
Every surface of a field operation. One OS.
AI decision engine
Next band, next park, next bird. Recommendations from live space weather and your log.
GNSS grids
Maidenhead from the phone GNSS. Distance and azimuth on every callsign.
Satellite ops
ISS, AO-91, SO-50. AOS to LOS with Doppler cues and SAT ADIF.
CAT control
IC-705, KX3, G90, FT-891. Frequency and mode belong to the radio and the log together.
FT8 companion
Decoder-speed capture beside WSJT-X. Grids you never retype.
CW-first rate
A log that keeps up with a paddle. Macros, RST, and DUPE without looking down.
POTA native
Park references, hunter/activator roles, and ten-QSO status on the line.
SOTA native
Summit codes, points, and glove-sized targets on the cone.
Cloud when you say
Encrypted sync is a replica. Offline is the source of truth.
ADIF & Cabrillo
LOTW, Club Log, POTA, Field Day. Exports that robots accept the first time.
Field security
On-device encryption, snapshots, and no log hostage to a login page.
Localization
Operators are global. The OS speaks more than one language — and still UTC.
11 — Product
Four skins. One log. Any light.
Dark for the shack. Phosphor for the field. Red for night vision. Vintage when you want the radio to feel like 1958 and log like 2026.
