Simple radio amateur logger
This is a single-file, offline-first app (hamradio_logger.html) — everything is kept in your browser, scoped to wherever you open the file from. Nothing is sent to a server.

Use Export ADIF any time to get a portable .adi copy of your log — this is the recommended way to back up or move your QSOs, since the browser storage above is local to one browser/profile and can be cleared by the browser.
