    Getting it Right

    In the article "'Improving Hurricane Preparedness' is National Hurricane Conference Theme," in the February 22 edition of The ARRL Letter, the time of the Amateur Radio Session is incorrect. The Amateur Radio Session will take place Tuesday, March 27, at 10:30 AM.


    The article "Postponed DXpedition to Disputed Spratlys Reset for March," in the
    February 22 edition of The ARRL Letter overlooked a two-person DXpedition from the Spratlys in 2016. James Brooks, 9V1YC, and Chris Burger, ZS6EZ, operated from Layang Layang Island for 6 days in May, making nearly 11,000 contacts. -- Thanks to Chris Berger, ZS6EZ
