Single Letters - Rapid-Fire 20wpm

The time is very short between the Morse code and hearing the answer spoken. This rapid-fire timing is geared to push your ICR (Instant Character Recognition) skills. First, each letter is sent in Morse code. Then it is spoken. And finally, it sent again in Morse code. If you missed something the first time when it was sent, the second time allows you an opportunity to learn it. 73 de AD0WE!
