Okay, I was searching Spectrum Analyzer. Thanks for the SDR link.


Am I right to understand that you by their RTL-SDR R820T2 RTL2832U 1PPM TCXO SMA dongle for $25, then you need to buy SDR software that would have a panadaptor component to use it as a Spectrum Analyzer?


If so what brand PC based SDR software do you recommend and how much does that add to the price of the system so to speak. I already have a Win 7 PC with an i3 processor that should work. Thanks.
