The fastest way to log SOTA and POTA contacts from the field. Type a callsign, hit Send, and you're ready for the next station. SOTA Log is built for operators who need speed on the summit, not menus, settings, or setup screens. ONE-FIELD LOGGING Type your entire QSO in a single field. Callsign, RST, frequency, mode, and references are parsed inline as you type. Frequency carries over. Mode derives from band. Everything you'd normally tap through just works. LIVE SPOTS Browse real-time SOTA and POTA spots filtered by program and mode. Tap a spot to prefill your QSO and tune your radio in one step. SOTACAT RADIO SYNC Connect to your Elecraft KX2, KX3, or KH1 for automatic frequency and mode sync, one-tap spot pouncing, and a CW keyer with six programmable macros. SOTAMAT SPOTTING Spot yourself via SMS with no cell data required. SOTA and POTA spots are sent through SOTAmat so chasers can find you even without internet. QRZ & ADIF Look up callsigns and sync your logs to QRZ Logbook. Export ADIF filtered for SOTA or POTA submissions. OFFLINE FIRST All logging works without internet. Reference databases, contact history, and activation progress live on-device. Network features enhance the experience but never gate it.
