My receiving setup
Raspberry Pi 4B + QFH antenna
A Raspberry Pi 4B paired with a homemade QFH antenna, capturing weather satellite images from NOAA and Meteor-M2 as they pass overhead — recorded, decoded and archived without me lifting a finger.

How it works
03 MODULES01Antenna
Homemade QFH antenna
A Quadrifilar Helix — circularly polarized and hand-built for the job. It gives clear, reliable reception of the satellite downlink regardless of pass geometry.
02Compute
Raspberry Pi 4B
The heart of the station, running raspberry-noaa-v2 to receive and decode passes, turning raw signal into finished weather maps.
03Storage
Auto-upload to Supabase
Once processed, every image is pushed automatically to a Supabase storage bucket — securely stored and ready to serve straight to this site.
