These are the most common callsigns of North American amateur radio operators participating in SOTA (Summits on the Air) as chasers. For each callsign, try to head-copy it. First, the callsign 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.
