Amateur radio operators, known as "hams," use a variety of frequencies and modes to communicate with each other and with other licensed users around the world.

The hobby is popular among individuals of all ages and backgrounds, from hobbyists to professionals in related fields.

Amateur radio operators often participate in emergency communications, disaster relief efforts, and other community service activities. They also play a role in international communication, particularly in remote or underserved areas where traditional communication infrastructure may be limited.

The hobby requires a certain level of technical knowledge and skill. Operators must obtain a license to operate on specific frequencies and must adhere to strict regulations regarding power levels, antenna use, and other technical parameters. This licensing process ensures that the hobby is conducted in a safe and responsible manner.

In summary, harrastusradioissa is a hobby and service that involves the use of radio communication for non-commercial purposes. It promotes technical skill development, public service, and international communication, and is regulated by national and international organizations. The hobby is enjoyed by individuals of all ages and backgrounds, and requires a certain level of technical knowledge and skill.
