Amateur radio, also affectionately known as "ham radio", is a hobby of constructing, experimenting and communicating. Once licensed, an amateur can operate two-way radio equipment from home, from vehicles and from anywhere in New Zealand -and in many cases when overseas too. Bands of radio frequencies in the radio frequency spectrum have been set aside for amateur radio use.
Guglielmo Marconi was an Italian inventor and the person who first adapted radio waves into a functioning communication system. After the initial idea of interconnected telegraphic systems, many people began experimenting with possibility of making it wireless. Rumors are that it could have been M.
Historically, literacy—in its many forms—has given the marginalized a way to speak and participate in a system that previously prevented them from doing so. And while the printing press revolutionized the way writing was exchanged and shared with the world, the invention of radio as entertainment, emergency, and communication technology had a similar effect on oral storytelling. From this, ham radio, also known as amateur radio, was born as a subset of commercial radio.
Amateur Radioalso called "ham radio", is a hobby followed by people in most countries of the world, using internationally coordinated, specifically designated, frequency bands. Each country or jurisdiction separately allocates the frequencies and licenses its operators to use specific power levels or modes of communication. They are issued a personal callsign that has letters reflecting their country's international callsign area, a number reflecting the state or region, and letters that particularize the callsign to them.

Amateur radio enthusiasts are, too. In a statement released earlier today, the American Radio Relay League released a statement saying that its members—amateur radio enthusiasts known as ham radio operators—were ready. Amateur radio operators are federally licensed to communicate over the airwaves.
An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service. Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation. As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication.
T wenty six years ago, Keki Darbary and Vilas Rabade, two amateur radio enthusiasts from Pune, were fiddling with their ham radio sets when they accidentally established contact with a Soviet astronaut aboard the orbital space station, MIR. They had a three-minute exchange, and a number of their fellow ham radio enthusiasts were also tuned into this conversation that took place on April 14, In many ways, it was the first social network — anyone with the right equipment could join, get a call sign, and start chatting.
