V roku 1925 bola na parížskej Sorbonne založená Medzinárodná rádioamatérska únia (International Amateur Radio Union – IARU). Bolo to 18.apríla, čo je dátum svetového dňa rádioamatérov. In more than eighty years, amateur radio has developed significantly, while there are currently more than three million amateur radio transmitters in the world.
On this occasion, several special stations such as 6H6IARU, 3G87IARU, LZ1WARD, EL2RL, HB9WARD, CR6IARU will be QRV. How will you celebrate world radio amateur day?
