In times of crisis and natural disasters, Amateur (HAM) radios are often used as a trusted and proven means of emergency communication.
Recent examples include the September 11, 2001 attacks on the World Trade Center in Manhattan, the 2003 North American blackout, and Hurricane Katrina in September, 2005, where amateur radio was used to coordinate disaster relief activities when other systems failed.
TACDA has been a supporter of Amateur Radio communication, and Amateur Radio Clubs, for decades. Clubs can provide information about licensing in their respective area, local operating practices and technical advice.
In the US, Amateur radio operators are required to pass an examination to demonstrate technical knowledge, operating competence and awareness of legal and regulatory requirements in order to avoid interference with other Amateur radio operators and other radio services.
