Winter Field Day exchanges were randomly selected so that each exchange had an equal probability of being selected. If you would like a slightly easier challenge, take a look at the Winter Field Day Exchange. It has the exchanges randomly selected so that they are roughly proportional to recent participation, which means that some types of exchanges are much more common than others.

For each exchange, try to head-copy it. First, the phrase is sent in Morse code. Then it is spoken. And finally, it is 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.
