Nets — regularly scheduled on-the-air meetings of hams who have common interests — are among the oldest ham radio activities. The first net was probably formed as soon as two hams went on the air. Sometimes, the nets are strictly for pleasure, to discuss topics such as collecting things, playing radio chess, or pursuing awards. Other nets are more utilitarian, such as those for traffic handling, emergency services, and weather reporting.
