Our correspondent in Brazil, for RHF Martin Butera PT2ZDX/LU9EFO, had access to PT2CVA, the official broadcaster of the famous Brazilian “Verde Amarelo” contest, organized by the Brazilian army communications school.
Our columnist in South America, Martín Butera, presents us with an interesting tour of this impressive South American contest station. With more than 10 towers and large stacked single band yagis, this is one of the most consistent calls in global and national contests.
Brazilian amateur radio also had its heyday, where several high-level technicians were created and brought communication to isolated corners of a giant country with continental distances such as Brazil. But times have changed, other communication technologies have been developed, giving way to WebSDR, today here we will know one of the most complete in the world and it is located in the interior of the city of São Paulo, Brazil.

Sebastiao has already lost count of how much equipment he has accumulated in his house, which now only serves to store the millions of transmitters that are scattered throughout all rooms of the house.
Collecting is a basic and very old human instinct, typical of organized, careful and somewhat obsessive people. Our interviewee is the opposite. Entering his garage in which he keeps a secret bunker where he hosts his radio collections, is like entering a trip to the origins of the cosmos, a collection of messy planets that at the same time work in perfect balance.
To start telling you the history of this radio, it is first necessary to tell you where this particular streaming station is located. Radio Lapa55, is located in the Selina Lapa Rio hotel, in Rio de Janeiro (Brazil). The Selina is a youth-oriented hotel, combining different styles of accommodation with modern design…
Martin Butera reports on one of the oldest university and free radio stations in Brazil, “Rádio Muda”, which broadcast since the mid-1980s inside the water tower of the State University of Campinas (Unicamp), in the state of São Paulo, Brazil.
Radio Guarujá Paulista began broadcasting in the city, according to the data provided by ANATEL (Agência Nacional de Telecomunicações – Brazil), between the mid and late 1940s. Currently the studios and transmitter plant is located in the area of Pitangueiras, a Santa Rosa neighborhood, duly assigned and domiciled in the street, José Vaz Porto, number 175.
The idea came in the early 2000s but the project was on hold for years because we had licensing issues. Then last year – at the start of the pandemic – we brought the idea back and the station was born as part of a project led by a non-profit, Turma Que Faz, which offers a range of arts and nature-based activities for kids in the area. It felt like the start of a small revolution and we were able to get the whole community involved.
