Has anyone used a HackRF One software defined radio as a spectrum analyzer? If so what SDR software did you use and how did it perform. My application is to do RF audits within homes/offices. Typical RF energy sources are microwave ovens (2.4GHz), wifi routers (2.4GHz/5 GHz), Cell phones, etc. Most spectrum analyzers that go up to 5GHz are somewhat expensive. The HackRF One is an amazing SDR that works up to 6GHz and costs about $300. Here's a link to the developer's site: https://greatscottgadgets.com/hackrf/one/
