📡 ELRS Wideband Spectrum Analysis (750–2700 MHz)

Wideband RF spectrum capture and comparison of ExpressLRS (ELRS) activity using HackRF One and Python.

This project captures a full sweep from 750 MHz to 2700 MHz, compares baseline vs active ELRS transmission, and generates visual spectrum plots to highlight RF activity and transmission footprint.
