Detecting the Next Astonishing Radio Signal Using Economical Software-Defined Radio (SDR)
The "Wow@Home" project, inspired by the legendary Arecibo Observatory, aims to bring the excitement of radio astronomy to the masses. This ambitious initiative, spearheaded by Mark Stevens, invites individuals to join in the quest to document the hardware and software necessary to pick up a "Wow! class signal" from their own homes.
The project continues to build on the concept of citizen science, allowing everyday people to contribute to scientific research. The team at Arecibo is working diligently on developing software for the "Wow@Home" project to analyze data received from the radio telescopes at home.
The software development is still ongoing, with the focus on improving the analysis of data coming out of the receiver. The finished product will be in Python and can be deployed on a Raspberry Pi, making it accessible for many. The software will generate a live preview of the data in the style of the original Ohio State SETI project printouts, ensuring a user-friendly experience at home.
The "Wow@Home" project is not the first instance of SDR-based homebrew radio telescopes, as such projects have been covered over the years. However, it stands out for its goal: to identify the source of the "Wow! Signal", a mysterious radio burst detected in 1977 and believed to be the result of a rare astrophysical event, not extraterrestrial life.
The process of building a radio telescope for the "Wow@Home project" is similar to many SDR-based homebrew radio telescopes, involving a dish, RTL-SDR, filters, amplifiers, and pointing it to the sky. The project does not require motorizing the dish, as the rotation of the Earth can be utilised to move the antenna at home.
The "Wow@Home project" is open to contributions from the community, specifically from individuals with experience in RFI shielding, software GUIs, and general software development. By participating in the "Wow@Home project", individuals become radio astronomers, contributing to the ongoing research into the legendary "Wow! Signal" at the University of Puerto Rico at Arecibo.
Join the "Wow@Home" project today and be a part of history in the making! The project is seeking assistance and community involvement to flourish, and with your help, we can unravel the mystery of the "Wow! Signal" together at home.
