Receiving live weather images from NOAA-18/19 satellites using a simple RTL-SDR dongle (v4). System Logic: Constructing a "V-Dipole" antenna tuned specifically to 137.5 MHz. The challenge is not electronics, but geometry: The antenna arms must be exactly 53.4cm long with a 120-degree separation angle to match the satellite's circular polarization signal path. 2026 software update: "SatDump" now automates the Doppler effect correction. System Focus: Signal Processing and Antenna Geometry.
