We invited Mr.Phatanadit Kulphaichitra to share a basic knowledge of amature radio and his experience during the 2004 Tsunami in Phuket. He was an ex-secretary of Amateur Radio Society of Thailand, http://www.qsl.net/rast. Recent natural disasters around the world such as the 2004 Tsunami in Phuket, the 2005 Hurricane Katrina and the 2011 earthquake in Japan would only made us realize the importance of this die-hard technology when all infrastructure failed.
