Ever wonder about the Kansas City DX Club Hospitality Suite. That's where they run the CW Challenge. You raise your hand. Wait your turn. When your time comes you are ushered into a private room and the fun begins. Outside the crowd watches the changes in the leaders and scores.



Here's a link to the History and a Sample of the test.

In an actual competition PileUpNetPlayer is the application used by the competitors to log the call signs they copy as a pile-up audio file is played on their machines under the control of the Host. Each entered call is sent to the Host for scoring. Using this Pileup Practice Application the user selects a competition from the past, logs the calls heard either on computer or paper, and at the end of the test session is presented a score and an analysis of the good and bad calls and, where available, is given a comparison of his results to the winning and average scores of the original competition. A history is kept of the results of each test session and can be reviewed as desired by the user.  Most of the competitions included in the practice data are those that have been held over the last 15-20 years at the KCDXC Hospitality Suite at Dayton.
