The W1AW Frequency Measuring Test (FMT) has taken several different formats over the past few years. This year, the ARRL returns to the “classic” FMT — measuring the frequency of an unmodulated carrier. Accurate frequency measurement is required of all hams for both regulatory compliance — “stay in the band!” — and operating convenience, particularly on the new digital modes. The W1AW FMT will run on November 12, 2009 at 0245 UTC (this is Wednesday evening, November 11, 2009 at 9:45 PM EST). It will replace any W1AW bulletin normally scheduled for that time. It is recommended that participants listen to W1AW’s transmissions prior to the event to get an idea of conditions to see which band (or bands) will be best for measurement purposes. Read more here.
