Koch Lesson 8: Add the Letter L

Why this step

L is four elements: dit-dah-dit-dit. It extends A (.-) with two extra dits. After P, you already know four-element patience; L tests a different tail.

What to hear

If you hear A and then two more dits, it is L, not A. R is only three elements (dit-dah-dit). Stopping early is the usual error.

Drill

Active set: K, M, R, S, U, A, P, T, L. This is the last indexable lesson on MorseCoder. Lessons 9–36 (O, W, I, and the rest of the 36-character order) stay inside the Koch module so we do not publish dozens of near-duplicate pages.

Letter groups you can type in the translator once the ear is warm: LA, AL, SL, LT

Pitfall

Treating L as “the long A.” Name L only after the two trailing dits. Then go back to mixed copy so L does not dominate.
