A browser-based Morse code trainer for practicing real amateur radio callsigns. The app sends randomly generated callsigns at your chosen speed; you copy what you hear and type it in. The app tracks your accuracy and rate over a timed session. Adjust speed (WPM), Farnsworth spacing, pitch and noise to suit your level; press the ` (backtick) key or ? key to hear a callsign again. A built-in detailed Help button in the title bar explains every feature.
Pick a region (US, Americas, Europe, Asia-Pacific, or CW Ops, real callsigns heard on the air) and see each call's speed and country in the Live Log.
