After an incredible Centennial year, the very special W100AW call sign will leave the air on December 31, just as the New Year arrives at 0000 UTC. QSL cards will be available as 2015 progresses.

Also, all ARRL Centennial year W1AW portable operations (now in Pennsylvania and Iowa) will end December 31 at 0000 UTC (the evening of December 30 in continental US time zones). -- Thanks to Dave Patton, NN1N
