The history of amateur radio is a fascinating journey through the development of radio technology and communities of enthusiasts from around the world. Amateur radio has played a key role in many aspects of life, from science and industry to public services and bringing nations together.

Between 1900 and 1908, Marconi continued his experiments, leading to growing interest in radio among people around the world. The first amateur radio operators began using Morse code to establish communications with spark-gap transmitters, laying the foundation for modern international and amateur radio.
Another important milestone in the history of amateur radio was the International Radiotelegraph Conference held in Washington in 1927–1928. At this conference, amateur radio bands were established and prefixes were introduced before call signs to identify the country with which they were associated. In 1979, during the World Administrative Radio Conference (WARC) in Geneva, radio amateurs were allocated three new frequency bands.

In Poland, amateur radio began to develop in 1924, when the first radio clubs and magazines devoted to radio topics were established. The Polish Amateur Radio Union was founded in February 1930 and played a key role in organizing amateur radio in Poland, especially during the difficult period of World War II.
After the war, in 1947, the efforts of amateur radio operators led to the reactivation of PZK, contributing to the further development of amateur radio in Poland. Today, many amateur radio stations operate in Poland, and the number of radio amateurs continues to grow, demonstrating the popularity of this hobby.
Another important step in the history of amateur radio came in 2003, when the World Radiocommunication Conference decided that knowledge of telegraphy would no longer be required to obtain an amateur radio operator licence. This reflected the changing needs and technologies in the field of radiocommunications.
In summary, amateur radio has played and continues to play an important role in the history of radio technology and in connecting people from different parts of the world. Thanks to the passion and dedication of radio amateurs, this remarkable hobby has survived and continues to develop, adapting to changing conditions and technologies.
