Field day is the one day in the year when amateur radio operators get to practice for an emergency in an organized way. Almost out of nowhere, antennas appear and hams all over the country focus on communicating by the many modes of radio technology available to them. These range from Morse code, to relaying messages from satellites flying overhead to hams halfway around the world. But it’s not all work. It is a fun time as well for young and young at heart.
