kQSO

kQSO is a ham radio logger with a single, smart input line. Type a whole QSO on one line — callsign, band and mode, report, serial, locator, award reference — and kQSO recognizes each part by its shape. A preview under the line shows what will be saved. Logs are plain ADIF files on your device; everything works offline. Log profiles Activation — SOTA, GMA, POTA, WWFF, TOTA lookout towers; your reference is set with the log, the other station's reference is logged for S2S. General — adds the name. VHF contest — serials, 6-character locator, IARU R1 scoring (points per km), score per band, EDI (REG1TEST) export per band. Satellite — one log per pass; the satellite sets uplink / downlink band and frequency. Logging Bands 160 m to 76 GHz, microwaves typed in GHz (24G, 10G …). Callsign suggestions and locator prefill from a bundled database and your own worked stations. Dupe warning (call + band + mode; contest per band; satellite per bird). QSO map of worked locators over the Maidenhead grid, offline. Rain radar on the VHF contest map (optional, off by default). ADIF export, push to your own Wavelog (API v2). Crash-safe: every QSO is written at once, an unfinished one is offered back after a restart. Radios and keyers (beta) Icom IC-705 over Bluetooth: band, mode and exact frequency from the radio, a typed band or F28300 tunes it, CW macros through the radio's keyer, voice memories T1–T4 in SSB / FM, transverters per band.
