Inexpensive Software Defined Radio Spectrum Analyzer < $10.00

Rabbit73,

I purchased three of these (SDR’s) directly from China and find them very useful. All of the spectrum analyzer graphics I post are captured through one of my SDR’s using a free program called RTLSDR Scanner. They only have ~50 dB dynamic range, but are capable of seeing signals down to ~-114 dBm. I wrote about my initial experiences here:
