How It Works

dit•DAHs™ is designed for people who want to understand Morse code—not memorize dots and dashes or chase shortcuts. The platform is built around the Koch Method, a structured approach used by experienced operators to develop true character recognition from the start.

Audio-first, not visual crutches

Most tools teach you to decode symbols visually. dit•DAHs trains your ear to recognize sound patterns—the way Morse code is actually used on the air.

Koch Method, done correctly

Characters are introduced at full speed from day one, with spacing adjusted to support recognition. No slow character speeds. No bad habits to unlearn.
