Five Challenging Letter-Number Combinations 15wpm
Channel: Kurt Zoglmann

Each practice trial is made up of a combination of five letters and numbers that are difficult to distinguish from one another — I S H 5 U V 4 D B 6 W J 1 T E. These differ from each other by the number of dits and dahs and are frequently difficult for beginners. For instance, di-dit (I) versus di-di-dit (S).

There is a slight pause before the answer is spoken, which is just enough time to say the letters/numbers out loud with ICR (Instant Character Recognition). For each combination, try to head-copy it. First, the combination is sent in Morse code. Then it is spoken. And finally, it is sent again in Morse code. If you missed it the first time when it was sent, the second time allows you an opportunity to learn the words. (More speeds below).
