You can communicate with people in your city, region, country, or even around the world. Some countries even allow amateur radio operators to send and receive messages over the internet.

Amateur radio has a long history, starting in the late 19th century. It has been used for scientific research, engineering, and even in times of emergency. Many amateurs also participate in contests, where they try to contact as many other amateur radio stations as possible in a given period of time. There are also special awards and certifications that amateurs can earn for their achievements.

To get a license, you need to pass an exam that tests your knowledge of electronics, radio equipment, and the regulations of your country. The license gives you certain privileges, like being able to use different frequencies and power levels. There are also different levels of licenses, with higher levels granting more privileges.

Amateur radio is a global hobby, with millions of people around the world participating. It is represented and coordinated by the International Amateur Radio Union (IARU), which has member societies in most countries. These societies work together to promote amateur radio and protect the interests of amateur radio operators.

So, in summary, amateur radio is a hobby where people use radio frequencies to communicate with each other.
