yep 4b field day is at least nation wide. every hardy, sun toughened ham that wants to and is able sets up on field day. improvised antennas and emergency power systems are the rule! field day is a yearly test of ham radios ability to get thru when nothing else can. 9-11 in new york ham radio was the most reliable communications going. that was in spite of the loss of 2 or 3 repeters on the wtc itself. hurricane katrina, same story. even in this age of cell phones and the internet old fashioned ham radio and the ingenuity of it's practitioners is still a most viable form of communications.73's aa5ez
