Amateur radio software projects — built in the open, deployed on GitHub Pages. No installation, no server, no account. Just a browser and a callsign.
A virtual fox hunt simulator for the WLD amateur radio club. Train direction-finding skills from your browser — no receiver required. Set up virtual transmitters, practice bearing estimation, and sharpen your ARDF technique before heading into the field.
A gamified morse code trainer for children aged 7 to 15, built on the scientifically validated Koch method. 130 levels, 4 play modes, no installation. Characters always play at 20 WPM — the brain learns to hear patterns, not count dots.
An interactive course on decibels and dBm for radio amateurs — developed with the WLD club. Covers the full dB scale from first principles: ratios, power levels, antenna gain, feedline loss, and link budget calculations. All in one clean web app.
A propagation planner built for the shack, not the laboratory. Answers the one question every HF operator actually asks: is it worth switching on the rig right now — and if not, when? Live solar indices, band-by-band outlook, all in one page.
An interactive world map that shows where you can make contact right now, on which band, and with which radio settings — based on your licence class, power, mode, and live space weather data from NOAA and WSPR. Built as a PWA: no installation, no account, works offline.
The Excel sheet on the field day table, replaced by a live scoreboard. N1MM Logger+ broadcasts every logged QSO over UDP, and the tracker fills in a station-by-band matrix in real time. ADIF import as a safety net, manual overrides for paper QSOs, and a public read-only snapshot on GitHub Pages so everyone can follow along. Runs on Windows and Linux, fully offline, plain JSON storage.
Read a log in almost any common format, edit it in a live grid, validate it against a contest or activation profile, and export a clean file with one click. Import ADIF, Cabrillo, EDI/REG1TEST, SOTA-CSV, FLE and generic CSV/TSV/XLSX. Split and merge columns, catch dupes, fill in DXCC and CQ/ITU zones from the callsign, and export to ADIF, Cabrillo, EDI, SOTA-CSV, JSON and more. Eighteen built-in profiles for POTA, WWFF, SOTA and the big contests. Everything runs in the browser, offline, with no backend and no telemetry. Your files never leave the device.
