From time to time, our club will have a formal presentation at our monthly club meeting.  This is where we keep copies of those presentations.

March 14, 2002 - Carl Luetzelschwab, K9LA, gave an insightful presentation on Propagation Predictions and Planning for Contesting and DXing. In the presentation, Carl taught us about the Effective Sunspot Number (SSNe) and how to use it in different propagation programs to most efficiently work a contest or DX.
