ABOUT
Licensed amateur radio operator since 1994, I dedicate myself to technical experimentation and long-distance communications. I maintain stations in São Paulo (PY2), Silveiras (PY2), and Itatiaia (PY1), in addition to operating mobile and portable stations.
My main area of interest is DX, especially CW. I also remain active in SSB, contests, and digital modes, exploring both operational efficiency and the technical evolution of these systems.
All computing infrastructure at my stations runs exclusively on GNU/Linux platforms. Specific needs for automation, system integration, monitoring, and data processing are addressed by custom solutions developed in Python and Shell Script, ensuring full control and flexibility over the operating environments.
Over more than three decades in amateur radio, I have participated in numerous expeditions and special activations, including operations on Brazilian oceanic and coastal islands, as well as commemorative events of national significance. These experiences involved logistical planning, field station deployment, and operation under challenging conditions.
Alongside my operational activities, I maintain a small collection of historic Brazilian equipment, preserving important milestones in the evolution of the electronics and telecommunications industries in Brazil.
Professionally, I work in corporate process management in information technology and SAP systems. I have technical training in data processing and electronics, followed by degrees in Law and History, with professional work as a historian and journalist. I also develop projects related to classic computing, software development, open-source culture, and the history of computing and telecommunications.

About this beacon
When I got into amateur radio, my first callsign was PU2WVT (Class C). Later, as I advanced in license class, I became PY2WVT. After some time in the hobby, when I decided to keep a beacon operating continuously, I chose to bring this original callsign back into active use.
The beacon is transmitted using a certified CB VR94 Plus transceiver, which was modified with a small Raspberry Pi Pico interface connected to the standard CW input via a P2 connector.
The firmware running on the Pico was developed in Python 3 and is responsible for generating the CW signal, operating in a continuous loop to provide stable and automated transmission.
The system source code is publicly available in my Codeberg repository, as a way to contribute to the community and encourage low-cost experimental projects.
Reports on the DX cluster are welcome.

QSL INFORMATION
After nearly 30 years as a member in good standing of the local association, I will no longer use the bureau system. All QSL cards received via the bureau through November 2024 were paid for through the PY2 Bureau on November 22, 2024.
I confirm contacts electronically every week on: LOTW
I occasionally upload contacts to the ClubLog and HDRLog databases.
