International Amateur Radio Day

International Amateur Radio Day is an international holiday dedicated to radio amateurs. These are specialists of different levels who use radio engineering and electronic devices for non-commercial purposes: conducting experiments, modernizing and improving existing devices, creating new ones, and more. The holiday is celebrated annually on April 18.

History

The creation of International Amateur Radio Day is linked to a significant event for all radio enthusiasts—on April 18, 1925, the International Amateur Radio Union (IARU) was founded in Paris. This non-profit organization arranges amateur radio gatherings and various competitions where the best experts from around the world can present their innovations in the field of radio engineering.

It was radio amateurs who discovered that using short radio waves allowed for greater range, thereby improving the quality of communication. A special amateur sector of radio frequencies was created, which could be used by radio enthusiasts for their own purposes. In summary, the creation of the IARU not only popularized the hobby of radio engineering but also paved the way for new uses of radio waves, enhancing radio communication!

Interesting Facts

• Amateur radio operators in many countries are often called “hams.” This nickname was given to them by professional radio network operators.
• There are European and World Championships in radio sport.
• Many people once thought radio amateurs were a problem because they were allegedly jamming radio signals with their antennas. This is a misconception, as they operate on different frequencies and do not interfere with public radio broadcasting.
