  • Electronic Submissions Via Email

    Files in the required Cabrillo format may be e-mailed directly to the contest robot for that contest at the appropriate e-mail address.


    The Subject of the e-mail must contain ONLY the participant's call sign, such as: SUBJECT: W1HQ (Don't use the example, please use your own call sign.)


    Do not include anything other than your call sign in the subject line of your email, such as contest name or category, the file extension of the log file.


    Text-based Cabrillo-formatted log files ending with .log, .txt or.cbr are the only file types accepted.


    Your log file should ONLY contain your call sign and the file type  (examples: W1AW.log, W1AW.txt or W1AW.cbr). Do not add anything else, such as  W1AW 2011 ARRL Sweepstakes Log Entry.log


    A file with anything other than the callsign in the name will cause your entry to be returned.


    Submit your log as a file attachment to your email. If possible, submit your log entry as a plain text email; this will reduce the chances that other attachments you may have to your emails (such as a background graphic, an image, logo or signature file) will not interfere with your submission. The Robot will reject submissions with more than one file attached.


    If the robot finds no problems, it will return a numbered receipt to you. You should keep this receipt as proof of submission.


    If the robot finds an error or problem it will return an email to you citing the problem and suggested corrections. You may re-submit the file to the robot with corrections as needed. Until you have a numbered receipt, you do not have a file in the queue for processing.


    If you find an error in your file after you have received a numbered receipt, simply re-submit the corrected file to the robot. Your previous file will be updated.


    Send files only in the Cabrillo format. We cannot use old style .sum, .dup or other file types. Sending these files will cause the robot to return your entry indicating an error. Word processor files, spread sheet files, zipped files and other files such as the BIN, QDF or PRN files produced by some of the logging programs are not readable by the robot and can not be processed. Logs for all contests except Sweepstakes must be emailed within 30 days of the end of the contest; Sweepstakes logs must be emailed within fifteen (15) days of the end of the contest.

  • Submissions Online

    If your logging program does not output the required Cabrillo format or if you log by hand, you may enter your data via and select the event of interest. You can input your log data which will be converted to a Cabrillo formatted log for you (it will generate a log and return it to you), and then you can in turn submit your Cabrillo log via email or web app.

    These applets allow you to input all of the required information for each contest -- both summary sheet information and individual QSO information. Once the data entry is finished, the applet will then submit the entry and supply you with a confirmation. It will also send an e-mail copy to you for your records. Web applet submissions must be completed no later than the published log deadline of the contest.

  • Confirmation of Logs Received by Contest

    The Logs Received page lists all received electronic submissions by contest. These lists are automatically updated several times during the day. It is not "instantaneous" so it may be several hours before the list is next updated.


    If you submitted your entry electronically and do not find your log listed, first please check to see that you received back a numbered receipt from the ARRL Contest Robot. If you have a numbered receipt and your log does not appear within several hours, please contact with your receipt number and they will look into the matter during regular ARRL business hours.


    Paper logs are not added to this electronic list, but will appear in the final results.

  • Paper Submissions

    While we strongly encourage you to convert paper logs electronically using the web applet, we still accept hand written paper logs. A paper printout of an electronically produced log is not acceptable. A paper submission must use an up-to-date summary sheet.

    Please do not use old forms. Only the most current summary sheet will contain the information about the latest multipliers, categories and other changes. Please either type or write the information legibly.

    Paper logs of 200 QSOs or more must include a dupe sheet -- an alphanumeric list of stations (call signs) worked, separated by band.

    For ARRL Sweepstakes, handwritten logs will be converted to electronic Cabrillo format by a team of data entry volunteers. We are not responsible for errors in your transcribed log due to illegible handwriting or missing information.

    Paper entries may be mailed to:

    ARRL Contest Branch
    225 Main St
    Newington, CT 06111

    They must be postmarked within 30 days after the end of the contest.
