Aquila Radio Observatory

A 24/7 live feed from my homebuilt 2.4 m radio telescope at a remote, low-RFI site, listening to the Milky Way at 1420 MHz: the hydrogen line. What you see is real data: the spectrum and waterfall updating live as the sky drifts through the beam.

I'm an amateur using SDR hardware and open-source tools to do genuine 21 cm radio astronomy. Data is published openly on Zenodo and here.

On this channel:

24/7 live hydrogen-line spectrum + waterfall

Real drift-scan data from the Milky Way

How it works: SDR, LNA, feed, calibration, RFI hunting

Coming soon - amateur SETI: Once the H-line pipeline is solid, I'll build a SETI experiment on top of it, narrowband detection, RFI discrimination, and drift-rate analysis. The odds are tiny, but the search is fun. Subscribe to follow the build.

Frequency: 1420.405751 MHz
Location: A remote low-RFI site in India
