Single Letter-Number Alt 20wpm

This practice set is composed of Letters and Numbers. As a set, letters and numbers are chosen with equal probability. Within each set, characters have the same probability of being selected. For each character, try to head-copy it. First, it is sent in Morse code. Then it is spoken. And finally, it is sent again in More code. If you missed it the first time it was sent, the second time allows you an opportunity to learn the words. 73 de AD0WE!
