What is Ham Radio?
Ham radio is a hobby and service that involves using the radio frequency spectrum for various purposes, such as communication, experimentation, education, and emergency assistance. Ham radio operators, also known as amateur radio operators or hams, need to obtain a license from their government to operate on certain frequency bands and follow certain rules. Ham radio allows hams to talk to other hams across the world, or even into space, using different modes of transmission, such as voice, text, image, and data. Ham radio is also a way to meet new people, learn new skills, and have fun!
