Log QSOs. Everywhere, later.

grglog is a free, fast web logbook for radio amateurs: keyboard-first manual entry with live locator prefill from GRG Rep, ADIF import/export, and an API your station software can log to in real time. Every QSO then fans out to Club Log, QRZ, eQSL, LoTW and friends on its own.

Create an account Log in Field logger — no account needed

• Fast entry — type a call, get grid + worked-before instantly, Enter logs it.
• ADIF in/out — tolerant import with a dedup preview; clean export by date range.
• Sync everywhere — QRZ Logbook, Club Log, LoTW, eQSL, HamQTH and HRDLOG get new, edited and deleted QSOs automatically, with retries and an honest status per QSO.
• Rig link — plug the radio into the browser (Yaesu, Icom) and frequency, band and mode fill themselves in.
• API — POST /api/v1/qso and GET /api/v1/lookup/{call} with per-app keys.
• Field logger — an installable app that works fully offline for POTA, SOTA and field days: no account, QSOs stay on your device, export ADIF anytime.
• No lock-in — your log is one export away, always.
