    Code practice text is from the pages of QST magazine, the League's membership journal. The source is given at the beginning of each practice session and alternate speeds within each session. For example, "Text is from July 1992 QST, pages 9 and 81," indicates that the practice session's plain text is from the article on page 9 and its mixed number/letter groups are from page 81.

    Directions to W1AW and ARRL HQ

    QSL Policy

    A number of years ago, it was required that visiting operators make out QSL cards for each and every contact they made while QRV from W1AW.

    While in the long-standing tradition of QSLing this once made perfect sense, over time it became apparent that this process lessened the importance of the QSL card. And, if nothing else, printing and postage costs became much more of an issue.

    Therefore, we ask that amateurs who work us and would like a W1AW QSL card to send us theirs first and to please include a SASE (Self-Addressed-Stamped-Envelope). Foreign stations may either QSL in a like manner (but send along an IRC) or just "via the bureau."

    Getting Bulletins via the Internet

    W1AW bulletins are available via email. ARRL Members can register for the Members Only Web site and select the categories of bulletins they wish to receive.
