Field Day: Submitting your Log

From Paul, KM4PT

Congrats!  The twenty-four-hour event has come to an end and you’ve got some contacts to contribute to the group score.  Awesome.

The ARRL wants you to use their web app form to submit your entry at:

When you go there in your browser, you’re going to be asked to fill out a form AND to submit your contacts.  

You can give them your contacts in the form of a Cabrillo formatted log OR a “Dupe Sheet” (which is simply a text file of your contacts categorized by band/mode with the call signs sorted alphabetically).

N3FJP can create Cabrillo files. And, on that same screen where Cabrillo files are created, there is a button labeled “Write Dupe File” that will create a Dupe Sheet for you.

  • Export your log using the Web Applet in a “Dupe Sheet” format

  • Use ARRL web app to submit your entry (and upload your log)


To submit your Field Day entry to the ARRL, do this:

  1. Delete any contacts from your log that you know need to be deleted.  (This could include any early contacts you created while testing.)

  2. In the N3FJP software, click the File menu and choose “Write Cabrillo (Contest Submittal) File…”
  3. In the pop-up form that appears, you can ignore all of those data entry fields!  (You’re going to fill out those fields online on the ARRL website.)
  4. At the bottom of the screen, click the button labeled “Write Dupe File” and you’ll be prompted to save the Dupe Sheet file to your computer.  (This is a text file that you can open with Notepad or any text editor.)
  5. You may also want to click the button labeled “Write / View Summary File” as this file contains a breakdown of the number of contacts per band/mode that you’ll need when filling out the ARRL web form. (You can derive this information from the Dupe Sheet but it’s broken down into a more easily viewable table in the Summary file.)

Okay, you’ve got your Dupe Sheet (or Cabrillo formatting log file) and you may also have your Summary file. It’s time to go to the ARRL Field Day data entry form to submit your entry.

The one important thing to remember when you submit your entry is to enter “WCARES-TN” in the field labeled Club or Group Name.
