This is not an official submission. This tool only allows you to check your results and prepare the submission through the spreadsheet available on the official CQ Magazine DX Marathon website.
Please note that this application use Country-File informations from AD1C. They may not be accurate for very specific callsigns, particulary for zone 2 and some USA stations. Please check official recommandations from the DX Marathon organizers.
If you want to withdraw a QSO from your log, you can delete it from your ADIF file or just add the ! sign before the callsign in the <CALL> field. This QSO will be then ignored.
Any new submission for the same callsign and year will erase the preceding one.
Please zip files if they are over 10MB in size. Limit for upload is 20MB.
