This past weekend, amateur (ham) radio operators in the Western Hemisphere participated in an annual emergency exercise called Field Day. In the event of a disaster, regular communications is often disrupted. Not only can cellular equipment be damaged, but the system can be overloaded by increased usage; in some cases, cellular communications can be limited to essential personnel ONLY by FEMA.
Most home telephones (for those who still have them) are not independent circuits, but are part of the house’s internet/cable television system. If power is lost, anyone with a wireless telephone won’t be able to use it.
Handling short range communications via amateur radio is relatively easy. Field Day is to practice as to how long range communications can be ensured without relying on existing systems. Our local club set up seven radio stations at a local park; antennas designed for the various operating frequencies were strung from trees, with the highest being at least 60 feet off the ground. The radios—along with computers, and the all-important coffee maker—were powered by solar cells or generators.
The actual communications portion of Field Day began at 2:00 PM on Saturday and continued around the clock. During that time, over 700 other stations were contacted; most were other stations set up for the drill, but there were amateur operators from around the world that made contact with us as well.
Most of us hope never to have a fire, but we have smoke alarms, fire extinguishers, and fire insurance. The few of us that do have a fire are relieved to have the additional protection. The same holds true for amateur radio’s role in communications. It’s not needed every day, but when it is needed, it can be a life saver.
The best part? Hams often arrive with their own equipment and provide the service at for free. THAT is the reason it’s called the Amateur Radio Service; hams cannot be paid for the services they provide.
