Swedish NAC data by SM7LCB

Last updated 19 Mars 2025.

I have done a summary of all Swedish NAC logs and tried to give a view of the activity and also which modes is used especially the trend between analog (CW/SSB/AM/FM) and digital (MGM). Some stations maybe is using MGM-program for CW but it is counted as analog in this summary. Some station also log MGM traffic as SSB so if so I check the connected stations log (if available) and if MGM there it is counted as digital else analog.

There is errors in the data some it shall be taken with some care:
- I may have done some bad analyst/coding (Excel and VBA script).
- Many stations is logging digital (MGM) QSO as SSB so some/many digital QSO is counted as analog in this summary.


This is my work to see activity and how activity change during year, years and contest hours.... maybe not the best presentation.
