I've made a QSO visualization for the CQ World Wide SSB 2025
<https://youtu.be/Nuel2_ue2Wg> contest along the same lines as the one I
made for CQP 2025 <https://youtu.be/muPMDw3ZoaU>. It shows the QSO's on a
world map as a function of time and band from start to finish, and the
world map shows the illuminated part of the Earth. The locations of some
stations on the map is approximate. The identification of QSO pairs from
logs is based on a relatively simple cross matching algorithm that I put
together, so the pairings aren't as carefully vetted as the ones I had from
CQP. I still think the video provides a sense of the major trends of the
contest and gives a sense of the scale of the contest.
CQ WW SSB has roughly 5 million QSO lines in logs for a 48 hour operating
window, and CQP has approximately 250 thousand QSO lines in logs for a 30
hour operating window. The QSO density per time is much higher for CQ WW
SSB, so the video is more about the macro features of the contest --
showing the larger scale regional shifts in QSO traffic. I hope to have a
similar video from the CW version of the contest in the next few weeks.
