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
