CVA DX Contest, CW

The Green and Yellow DX Contest (in Portuguese CVA DX HF Contest) is one of the Brazilian’s most important
amateur radio events, now in its 65th edition (2024), which reflects its long-standing tradition and proficiency
demonstrated over the years. The CVA DX Contest always takes place on the third full weekend of August for
CW (Morse Code) and the fourth full weekend of August for SSB (Voice).
It’s part of the celebrations of the Brazilian Soldier's Week by a Ministerial Notice on June 16, 1972. The CVA DX
Contest aims to foster friendship among radio amateurs and amateur radio organizations - both civilian and
military - from around the world. It also seeks to engage radio amateurs in the commemorative activities of
Soldier's Week, highlighting events related to August 25th and honoring the image of Duque de Caxias, the
patron of the Brazilian Army.
Known as the Green and Yellow Contest or CVA DX Contest, it holds the title of the most traditional amateur
radio contest in the Brazilian history. Over more than 50 years, it has developed progressively, aligning with the
formats of global contests. The Brazilian Army, through the Brazilian Army School of Communications, promotes
amateur radio practice and recognizes its importance in the country's development. Through over half a century
of contests, it demonstrates Brazil's affection and enthusiasm for the CVA DX Contest. Since opening its doors
to the world in 2011, the CVA DX Contest has rapidly gained international recognition, showing the importance of
the amateur radio in Brazil to the global community
