Using a SDR as a RFI Site Survey Tool

This article explains how software-defined radios (SDRs) are used to detect and visualize radio frequency interference (RFI). In part one, Dave details the process of capturing and analyzing RFI on the 80-meter band over a 24-hour period using tools like S-Meter Lite and Spectrum Lab. The SDR's wideband capabilities help identify and document RFI sources across large frequency ranges, making it a valuable tool for RFI detection and mitigation.
