Winter Field Day ADIF Log Example

Greetings friends! Submitting your log is how you get credit for your Winter Field Day contacts. The good news is we don't require anything special from you. The bad news is not everyone knows the basics about log formats.
 
This post will show you an example of a properly formatted ADIF log file, and where you can go to get more information about this format. First, all this comes from the ADIF specification at: https://adif.org/. You can always refer back to there for authoritative ADIF information.
 
We require seven fields. Five of them are the minimum all ADIF logs require. The other two capture the WFD exchange:
  • CALL 
  • QSO_DATE 
  • TIME_ON 
  • BAND 
  • MODE 
  • CLASS 
  • ARRL_SECT
 
Check out the example below.The field names MUST be correct to ensure correct log processing and QSO credit. For example, if your class data is in a field called FARTS instead of CLASS, our system may read your log as missing all class data and return zero QSOs. Incorrect field names are the most common reason for ADIF log rejection. 
 
That's it. If you ever have trouble with your log, you can always email us at helpdesk@winterfieldday.com
