MorseCodes.org

Morse code is a small subject buried under a lot of wrong answers: inverted patterns, invented punctuation, timing that would not survive a real key. This site is the correct, quiet version — one pattern per character, shown exactly, with its source named.

Everything is free, needs no account, and works the same on a phone and a desk. The pages load fast because there is very little to load: system fonts, no scrolling animations, no image payload on the reference pages.
