HSC Marathon Calculator

This little tool helps you to calculate your score for the annual "Marathon" of the Radio Telegraphy High Speed Club (HSC).

Check out the HSC Website for more information (including current member lists, etc.).

NB:

• QSOs from from other years than the selected year are automatically ignored. Nevertheless, please try to avoid uploading unneccessary data. Most logbook software lets you specify a date range when exporting to ADIF.
• No data is permanently stored on this server. The ADIF file will be deleted as soon as it's processed, the Excel output files are automatically deleted at regular intervals (1h) and are never visible to the public.
